RememberGliese 581 g ? The potentially inhabitable “ 2d ground ” 20 light years away , also know as Zarmina ? It ’s been look dicey for a while , as many astronomers questioned its very existence .

But now , Gliese 581 chiliad has been re - add to the top five list of exoplanets considered premier nominee for harboring of life . New data from Steven Vogt of UC Santa Cruz clearly designate that it ’s quite real . And what ’s just as exciting is the realization that there are now two potentially habitable planet revolve the same star .
Gliese 581 yard was in the beginning fall upon by astronomers of the Lick - Carnegie Exoplanet survey in 2010 , but subsequent view were unable to detect it .
The satellite is about 1.5 times the size of Earth and it have a like amount of sun . Though it orbits a red gnome , it resides within its sunshine ’s habitable zone and is considered the good exoplanetary candidate for animation yet expose .
As Abel Méndez of Planetary Habitability Laboratorynotes , “ These factors meld to make Gliese 581 g the most Earth - similar planet know with an Earth Similarity Index , a measure of Earth - alikeness from zero to one , of 0.92 and high-pitched than the previously top candidate Gliese 667Cc , discovered last yr . ”
And indeed , the Gliese system , with its two potentially life sentence - friendly planets , may be our dependable wager when consider our first interstellar missionary station . At 20 unclouded - years away , it ’s remove the most exciting solar system in our straightaway neck of the woods .
Other planets surmise of shield life include Kepler-22b , HD85512 , and Gliese 581d .
