'Thrillingly, this planet is the closest Earth-sized and temperature planet we know,' the researchers say.
Scientists have discovered a new planet which they say could 'potentially support human life.'Gliese 12 b is a rocky planet just 40 light-years away from our own. It orbits around a star called Gliese 12, a cool red dwarf in the constellation Pisces. This star is only 27 percent of the size of our sun, with about 60 percent of its surface temperature. But it's this lower temperature that makes Gliese 12 b theoretically habitable for humans.
'So what criteria do scientists look for when assessing whether a planet could support human life?'This mainly depends on how close the planets are to their equivalent of the Sun,' the university's spokesperson said. 'Too close and all the surface water evaporates into space. Too far and the water freezes. Either way, life wouldn't be possible, and the temperatures wouldn't support human life.
