There is 'an Earth' around our nearest star, scientists confirm The planet, called Proxima b, is approximately 4.2 light years away. More tilted orientations imply a higher mass, with 90% of possible orientations implying a mass below 2.77 M⊕. The bottom right image shows Proxima Centauri — the closest star to the solar system, orbited by the planet Proxima b — while the bottom left image shows the pairs of stars called Alpha Centauri A and B. Proxima b may have some very broadly defined characteristics that parallel Earth, but so do many other exoplanets that are definitely not habitable. Nailing down the mass of a distant planet with such precision is "completely unheard of," said 2019 Nobel Prizer winner Michel Mayor, who laid the groundwork for the technology that made the discovery possible, in the statement. Kristen Walbolt Proxima b is a super Earth exoplanet that orbits a M-type star. There was a problem. However, it is much closer to its star than Earth is to the Sun. If the Earth were in Proxima b's location and the same distance from Proxima b's star and the Pacific Ocean was starside, things might look something like this. If the planet lacks an atmosphere, surface temperatures may be as low as minus 40 degrees Fahrenheit (minus 40 degrees Celsius). It is slightly closer to Earth than Alpha Centauri A and Alpha Centauri B, which are 4.35 light years away. The planet, called Proxima b, was also dubbed 'a second Earth' because is the right distance from its star to host liquid water, which means it has the potential for alien life.
