Our journalists will try to respond by joining the threads when they can to create a true meeting of independent Premium. Kepler-452 is a G-type main-sequence star located about 1,402 light-years away from Earth in the Cygnus constellation. Kepler 452b is warm, possibly wet, and might be able to host plant life - however, it's 1,400 lightyears away. Consequently, Kepler-452b is named as Super-Earth. 22b is inside its star’s habitable zone. An artist's impression of Kepler 452b, the most Earth-like planet ever discovered When looking for planets that might support life, scientists start with the habitable zone. Not a lot. It has the longest year of any transiting planet of its size, holding the door open to finding more diverse planetary system. It orbits a sun-like star once every 384.84 days. The illustration represents one possible appearance for Kepler-452b -- scientists do not know whether the planet has oceans and continents like Earth. We won’t be able to answ… Due to the sheer scale of this comment community, we are not able to give each post the same level of attention, but we have preserved this area in the interests of open debate. The discovery of Kepler-186f confirms that Earth-size planets exist in the habitable zones of other stars and signals a significant st Nasa's New Horizon probe - the one that recently took the amazing pictures of Pluto - left Earth's orbit faster than any other spacecraft before it, at around 36,373 mph. This puts the Kepler-452b in the so-called “habitable zone”; a term that sounds excitingly promising for life, but is actually misleading. Nasa scientists have announced the discovery of Kepler 452b, also known as 'Earth 2.0', an earth-like planet in our galaxy. The artist's concept depicts Kepler-186f , the first validated Earth-size planet to orbit a distant star in the habitable zone—a range of distance from a star where liquid water might pool on the planet's surface. Read our full mailing list consent terms here. Much more research on the planet is still being done, which will be able to confirm whether anything could thrive on Kepler 452b. Since Kepler launched in 2009, twelve planets less than twice the size of Earth have been discovered in the habitable zones of their stars. This list shows all planetary and stellar components in the system. This planet is about 60% larger than the Earth. The habitable zone is a region around a star where temperatures are right for water—an essential ingredient for life as we know it—to pool on the surface. The planet is also 5% further away from its star, than the Earth's 92million miles to our sun, at 96,6 … Kepler 452b "is the closest thing we have to another place somebody might call home," Jon Jenkins, Kepler data analysis lead, said in a news conference call on Thursday. Assuming a density close to that of Earth, Kepler-452b would have a mass about five times more than the Earth. Kepler-452b receives 10% more energy from its parent star than Earth receives from the Sun. Kepler 452, the planet's star, is around 1.5 billion years older than our Sun. A planetary tour through time. The newly discovered Kepler-452b is the smallest planet to date discovered orbiting in the habitable zone — the area around a star where liquid water could pool on the surface of an orbiting planet — of a G2-type star, like our sun. Kepler 452B: Nasa announces discovery of new planet seen as 'close cousin' to Earth. We don’t know whether life exists on Kepler-452b, but we do know that it has some things in common with the Earth. The confirmation of Kepler-452b brings the total number of confirmed planets to 1,030. Everything about Kepler 452b - from its size, the length of its years, the estimated conditions on the surface - is very similar to Earth. This means that Kepler-452b is a world older, and the habitable zone inside its star has been around for 6 billion years. As a result Kepler 22b is considered as one of the best exoplanet candidates for habitability. A year on Venus, sometimes the closest planet to the Earth, lasts only 88 Earth-days. Its diameter is 60 percent larger than Earth’s, which means it likely has a rocky surface. The habitable zone, also known as the 'Goldilocks Zone', is an area around a star which has just the right temperature to allow for liquid water to exist. Kepler 442b is known as a super-Earth, so let's we are Kepler 442b Learn more about here. 1. Kepler-452b may be Earth’s close cousin, but living on the newfound world would still be an alien experience. The habitable zone is the region around a star where temperatures are just right for water to … The clouds on the planet would be thick and misty, covering much of the surface as viewed from space. Here we get a lot of information about Kepler 442b. Jon Jenkins said that humans could "adapt" to the gravity, possibly becoming "more stocky over many generations. The new planet is slightly larger than Earth, and is estimated to have twice the gravitational pull of our own planet. Kepler-442b (also known by its Kepler object of interest designation KOI-4742.01) is a confirmed near-Earth-sized exoplanet, likely rocky, orbiting within the habitable zone of the K-type main-sequence star Kepler-442, about 1,206 light-years (370 parsecs), from Earth in the constellation Lyra. If a planet is too close to its star, it will be too hot to host life. For one thing, NASA reported, it’s 60 percent larger in diameter than Earth and its orbit is 385 days. It's Earth 2.0.". Which means it will take us 1,400 years to reach Kepler 452’s planet system, provided that we travel at the speed of light. This set of travel posters envision a day when the creativity of scientists and engineers will allow us to do things we can only dream of now. The newly discovered Kepler-452b is the smallest planet to date discovered orbiting in the habitable zone -- the area around a star where liquid water could pool on the surface of an orbiting planet -- of a G2-type star, like our sun. Kepler-452b was found to be 60% larger than the Earth. While Kepler-452b is larger than Earth, its 385-day orbit is only 5 percent longer. There are 4,696 planet candidates now known with the release of the seventh Kepler planet candidate catalog - an increase of 521 since the release of the previous catalog in Jan. 2015, Highlighted are new planet candidates from the seventh Kepler planet candidate catalog that are less than twice the size of Earth and orbit in the stars' habitable zone—the range of distances from a star where liquid water could exist on the surface of an orbiting planet. Want an ad-free experience?Subscribe to Independent Premium. Twelve Exoplanet discoveries from Kepler that are less than twice the size of Earth and reside in the habitable zone of their host star. There’s more to it than the similarities mentioned here. Jon … As a result Kepler 22b is considered as one of the best exoplanet candidates for habitability. The Goldilocks Zone is where the temperature is optimum for life to exist and also for water to exist in liquid state. If a spacecraft carrying humans travelled at this speed towards Kepler 452b, it would take the unlucky astronauts around 25.8 million years to get there. Comparison between Earth and Kepler-452b and their host stars Scientists using data from NASA's Kepler mission have confirmed the first near-Earth-size planet orbiting in the habitable zone of a sun-like star. But what we do know is enough to be exciting. Although the planet is far too far away to photograph, advanced Nasa technology means we know a surprising amount about this 'New Earth'. Kepler-452b has a diameter 60 percent larger than Earth and is considered a super-Earth-size planet. This is an issue because it was most likely our giant gas planets that helped direct water to Earth. It allows our most engaged readers to debate the big issues, share their own experiences, discuss real-world solutions, and more. This world might have water and active volcanoes. Image via SETI Institute/Danielle Futselaar. It has the longest year of any transiting planet of its size, holding the door open to finding more diverse planetary system. Scientists have described Kepler-186f as a cousin to Earth. This artist's concept depicts one possible appearance of the planet Kepler-452b, the first near-Earth-size world to be found in the habitable zone of star that is similar to the Sun. The ancients debated the existence of planets beyond our own; now we know of thousands. It takes 385 days to orbit its parent star Kepler-452, and it is only 5 percent further from the star than the distance between Earth and the sun. The confirmation of Kepler-452b brings the total number of … Planet 452b takes 385 days to orbit its star, just a little more than Earth takes for a one-year lap. That does not mean that Kepler-452b is not a fantastic find. The planet's star, Kepler 452, is slightly bigger than our own Sun. A year on the newly-discovered planet - the time it takes to orbit its star, Kepler 452 - lasts for 385 days, only 20 days longer than a year here on Earth. Alongside this, the star is approximately six billion years old and possesses a high metallicity. Jon Jenkins told the press conference: "The sunshine from Kepler's star is very similar to sunshine from our own star, and plants could be able to photosynthesise just the same. 1,400 light-years away in the constellation Cygnus, Kepler-452 is a 6 billion years old Sun-like star. This planet is about 60% larger than the Earth. Kepler-452b is the first planet orbiting a star about the same size and temperature as the sun. Kepler 22b orbits inside the habitable zone of its host star, with an Earth like atmosphere the planet could enjoy comfortable temperatures of around 22C (72F), allowing for the presence of liquid water on its surface. It takes just a little longer to travel around its sun than Earth, having 20 days more in each year, and is around 60% bigger than our planet. Kepler-452b receives 10% more energy from its parent star than Earth receives from the Sun. Assuming a density close to that of Earth, Kepler-452b would have a mass about five times more than the Earth. Kepler-452 b, planet, semi-major axis: 1.046+0.019−0.015AU The habitable zone is a region around a star where temperatures are right for water — an essential ingredient for life as we know it — to pool on the surface. Kepler 452b "is the closest thing we have to another place somebody might call home," Jon Jenkins, Kepler data analysis lead, said in a news conference call on Thursday. This means plants from our planet could grow there if it were rocky and had an atmosphere. They have been using the Allen Telescope Array – a group of 42 antennas north of San Francisco – to monitor various frequencies for radio signals and search for sophisticated life on Kepler 452b. It could have water in liquid state It is located in the ‘Goldilocks Zone’ of its solar system. The planet, possibly rocky and named Kepler-452b, is orbiting 1,400 light-years away within its star’s “habitable zone,” a region where water, essential for life, could exist in liquid form. As far as we know, there are no other planets in the same system. Kepler 452b has been the perfect distance from its star for many billions of years. Its star, Kepler 452, is also older and bigger, as well as brighter than our sun. Another problem is that Kepler-452b is alone. It means that we could inhabit this planet someday in far future.

Kepler 452b, the most Earthlike exoplanet found so far, could have a rocky surface with pools of water and a thick atmosphere. Kepler-452b is much more lonely than us with only one other planet in its system. Light travels at over 670 million miles per hour. Kepler-452, stellar object 1.1. That does not mean that Kepler-452b is not a fantastic find. Kristen Walbolt A unique feature of the seventh Kepler candidate catalog is that it is the first to fully automate the assessment of transit-like signals. Kepler 442b is confirmed in close proximity to the earth-shaped exoplanet. If it is a terrestrial planet, it is most likely a super-Earth with many active volcanoes due to its higher mass and density. Kepler-452b is 5 percent farther from its parent star than Earth is from our sun. It's slightly warmer than Earth, slightly larger, could have liquid water on the surface and it's 1,400 light years away, Find your bookmarks in your Independent Premium section, under my profile. ", Dr Daniel Brown, an astronomy expert at Nottingham Trent University, said: "Kepler 452b receives the same kind of spectrum and intensity of light as we do on Earth. If Kepler-452b had the same mass as Earth it would be on the verge of experiencing the runaway greenhouse effect and the loss of its water inventory. Are you sure you want to delete this comment? It's the closest so far. However, there is uncertainty about the size, and, given the fact that we know nothing about the composition (and hence density) of Kepler-452b, these figures are at best crude estimates. Both Kepler-438b and Kepler-442b orbit red dwarf stars that are smaller and cooler than our sun.Kepler-438b circles its star every 35 days and receives about 40 percent more light than Earth; it's estimated to have a 70 percent chance of being in the habitable zone of its star.Kepler-442b completes one orbit every 112 days and gets about two-thirds as much light as Earth.

The scientists give it a 97 percent chance of being in the habitable … Kepler-452b is the first planet orbiting a star about the same size and temperature as the sun. Kepler-452b also orbits a G2-type star, is likely to have a cloud-based atmosphere, has a good chance of being a rocky planet, and has a year that lasts 385 days – only 5% longer than an Earth year. They have been using the Allen Telescope Array – a group of 42 antennas north of San Francisco – to monitor various frequencies for radio signals and search for sophisticated life on Kepler 452b. The newly discovered planet, Kepler-452b, is the smallest planet found to date that orbits a Sun-like star in the habitable zone, the area around a star where liquid water … The planet has an atmosphere that could contain water and therefore extra-terrestrial life Now Punjab Chief Minister Captain Amarinder Singh has ordered a … That movie was named as Shooter. If Kepler-452b had the same mass as Earth it would be on the verge of experiencing the runaway greenhouse effect and the loss of its water inventory. Over the course of years of data-gathering by the Kepler space telescope and even more analysis and work here on Earth, scientists confirmed the existence of the distant exoplanet, which is the most earth-like planet ever discovered. Kepler 22b orbits inside the habitable zone of its host star, with an Earth like atmosphere the planet could enjoy comfortable temperatures of around 22C (72F), allowing for the presence of liquid water on its surface. However, there is uncertainty about the size, and, given the fact that we know nothing about the composition (and hence density) of Kepler-452b, these figures are at best crude estimates. What does this mean? Please continue to respect all commenters and create constructive debates. Proclaimed by NASA, travelling to Kepler-452b seems to be an impossible task due to … Scientists don’t know if Kepler-452b can support life. NASA's Kepler mission has confirmed the first near-Earth-size planet in the “habitable zone” around a sun-like star. What the models tell us (with a reasonable degree of probability) is that Kepler 452b is likely to have a dense atmosphere (because of its size) and is likely to have liquid water. The newly discovered Kepler-452b is the smallest planet to date discovered orbiting in the habitable zone — the area around a star where liquid water could pool on the surface of an orbiting planet — of a G2-type star, like our sun. Light from the Sun takes around eight minutes to reach Earth, so naturally, a trip to Kepler 452b would take an incredibly long time. Kepler-452b is larger than Earth, but its 385-day orbit is only 5 per cent longer. The rocky alien planet Kepler 186f is an Earth-size world that could have liquid water on its surface, and possibly even life. When looking for planets that might support life, scientists start with the habitable zone. They recently found a system 1400 light years away that matches up to ours. Kepler 452b is possibly the right temperature to allow liquid water to exist on the surface - as far as we know, this is essential for supporting life. If there are elements necessary for biological life on the Kepler-452b surface, including liquid water and a favorable atmosphere, life can flourish in this world. Today Kepler-452b is receiving 10 percent more energy from its parent star than the Earth is from the Sun. The confirmation of Kepler-452b brings the … For instance, Kepler-452b takes 385 Earth days to complete its orbit around its star, which is only a bit longer than one Earth year. It gives a quick overview of the hierarchical architecture. Kepler-452b probably has a thick atmosphere, liquid water and active volcanoes, but these are best guesses based on modeling work. You could even get a healthy tan like here on holiday.". Kepler-452b is made of rocks and metals whereas the planet seems to have chances of habitual life in the future. Start your Independent Premium subscription today. Kepler 452b is an earth-like planet orbiting a sun-like star, Kepler-452, located in the constellation Cygnus. ", "People already adapt to heavy weights - humans are built to do this kind of thing. Kepler-452b falls neatly into line with those criteria. According to the space agency, the Kepler exoplanet explorer telescope discovered a planet and star … Kepler 452b has been the perfect distance from its star for many billions of years. Well, NASA says it does and its name is Kepler 452B. Please be respectful when making a comment and adhere to our Community Guidelines. Read on for more amazing facts on Kepler 452b planet. According to John Coughlin, a researcher at the SETI Institute in California, the Kepler team worked with geologists to find out the make-up of the planet. It is the smallest planet yet discovered that orbits in the habitable zone around a sun-like star. The added light and heat energy that the planet receives from the star not only means it is slightly warmer than Earth, but could also mean that plant life could thrive there. Kepler-452b is about 60 percent larger than Earth and orbits its parent star, Kepler-452, once every 385 days — just 20 days longer than Earth orbits the Sun. Today we have to talk about an astronaut planet named Kepler 442b. You can also choose to be emailed when someone replies to your comment. Thus, Kepler 452b should have a weaker rate of water photolysis for the same water vapor mixing ratio as present Earth's. While its mass and composition are not yet determined, previous research suggests that planets the size of Kepler-452b have a good chance of being rocky. Pyle) 452b is described as “a pretty good, close cousin to the Earth” by NASA’s John Grunsfeld. The Kepler team have calculated that it should have a temperature of 22 degrees C, just right for liquid water - or so you might think. The human body has an amazing ability to repair itself - so over time, humans could adapt.". Independent Premium Comments can be posted by members of our membership scheme, Independent Premium. Artist’s concept of Earth cousin Kepler 452b. It orbits a star 490 light-years away. Kepler-452b. And since plant photosynthesis is what produces the air we breathe, that means this essential building block of life has a good chance of living on Kepler 452b. If it's too far away, it will be too cold. That's much different to years on other, closer planets to Earth. Sign up for Scientific American ’s free newsletters. Although similar in temperature to the Sun, it is 20% brighter, 3.7% more massive and 11% larger. A year on Neptune, further out in our solar system, is the equivalent of 185 Earth-years. But this estimate depends on what sort of atmosphere the planet has. However, according to the scientists on the Kepler team, this doesn't mean it couldn't support life. An artist's impression of Kepler 452b, the most Earth-like planet ever discovered, This image compares the size of Earth with the size of Kepler 452b, Kepler 452b was named after the telescope that spotted it, the Kepler space telescope, This artist's impression shows what the surface of Kepler 452b could look like, with active volcanoes and liquid water, The sweep of NASA Kepler mission’s search for small, habitable planets in the last six years, A graphic of the crafts that have carried out Exoplanet missions, This size and scale of the Kepler-452 system compared alongside the Kepler-186 system and the solar system. ...

What is known about the planet is that it is about 60 percent larger than Earth, placing it in a class of planets dubbed "super-Earths," with an orbit of 385 days. Until its discovery in 2015, the Kepler telescope had only detected 12 Earth-size planets (smaller than twice the size of Earth) in the habitable zone of their smaller and cooler stars. It does, however, have an orbit that lines up similarly with ours. Kepler-452b is the first near-Earth-size world to be found in the habitable zone of star that is similar to our sun. Are you sure you want to mark this comment as inappropriate? Banned by the state government, Shooter, a Punjabi movie glorifying the life of slain gangster Sukha Kahlwan, has been leaked on Internet. According to Jon Jenkins, the Kepler data analysis lead at NASA's Ames Research Centre, this means it's possible that it hosts life on its surface, or at least could have at some point in its history. The habitable zone is a region around a star where temperatures are right for water—an essential ingredient for life as we know it—to pool on the surface. The Kepler-186 star is dimmer than the sun, so the planet may be somewhat similar to Earth in size, but its star is not the same as the sun. Kepler 452b is located around 1,400 light years from Earth in the constellation of Cygnus. In addition, water outgassing from the mantle reservoir can compensate for surface water loss and extend the time of water existence on Kepler 452b. At our position from the sun, the dust grains that came together to form the Earth were too warm to contain ice. Kepler-22b is the first confirmed planet in the "habitable zone," the area around a star where a planet could exist with liquid water on its surface, that has been discovered by NASA's Kepler mission. Kepler-442b (also known by its Kepler object of interest designation KOI-4742.01) is a confirmed near-Earth-sized exoplanet, likely rocky, orbiting within the habitable zone of the K-type main-sequence star Kepler-442, about 1,206 light-years (370 parsecs), from Earth in the constellation Lyra. Kepler-452b, the first approximately Earth-sized planet to be found in a Sun-like star’s habitable zone—the orbital region where an Earth-like planet could possess liquid water on its surface and thus possibly support life. The artistic concept compares Earth (left) to the new planet, called Kepler-452b, which is about 60 percent larger. Kepler 452b is about 60 per cent larger than Earth (Artist’s impression: NASA/JPL-Caltech/T. Kepler-452b probably has a thick atmosphere, liquid water and active volcanoes, but these are best guesses based on modeling work. Curious Kids is a series by The Conversation, which gives children the chance to have their questions about the world answered by experts. Scientists believe that Kepler-452b is about 6 billion years old, much older than Earth. Despite its likeness to Earth and its orbit around a star at a distance that could allow liquid water to pool on the surface, Kepler-452b does have differences. Beginning the conference, John Grunsfeld, associate administrator for Nasa's Science Mission Directorate in Washington, said: "Today we're announcing the discovery of an exoplanet that as far as we can tell is a pretty close cousin of Earth.
