On Aug. 24, astronomers announced they had found a possibly Earth-like planet orbiting Proxima Centauri, the closest star to the sun. The planet, called Proxima b, is about 1.3 times the mass of Earth and is 4.22 light-years away.
Main Story: Found! Potentially Earth-Like Planet at Proxima Centauri Is Closest Ever
Scientists have found clear evidence of a planet around Proxima Centauri, the closest star to our sun. The planet, called Proxima b, appears to be rocky and might be warm enough to host liquid water, and thus be habitable.
See our complete coverage of this newfound world, known as Proxima b, which may be able to host life:
