Super Earth Orbiting Barnard’s Star That Could Have Extraterrestrial Life and 15 More Interesting Images
2 Mins Read
Astronomers have evidence of an icy Super Earth, named “Barnard’s Star b”, that is about 3.2 times more massive than our planet, orbiting Barnard’s Star, a dim red dwarf that lies a mere 6 light-years away from the sun. Barnard’s Star is actually our sun’s nearest neighbor, next to the Alpha Centauri system, which is approximately 4.3 light-years away. Since it’s twice as old as Earth’s sun, one-sixth as massive and just three-perecent luminous, its “habitable zone” lies extremely close-in, or 0.06 AU to 0.10 AU from the star to be exact. Scientists believe the planet is extremely cold with temperatures around -150° C and its core could be made of hot iron or nickel, but due to enhanced geothermal activity, extraterrestrial life could flourish.
