Astronomers have discovered a faraway planet on which humans could potentially live. Named Gliese 581g, this planet orbits a red dwarf star once every 37 days. It’s believed to have a rocky terrain, an atmosphere and liquid water. The distance to this planet’s star means it’s likely not too hot nor too cold.
Gliese 581g orbits one of the 100 closest stars to Earth. Located 20 light-years away, this Earthlike-planet is one of at least seven in its solar system.
