The newfound world, a "super Earth" called Gliese 163c, lies at the edge of its star's habitable zone — that just-right range of distances where liquid water could exist.
"There are a wide range of structures and compositions that allow Gliese 163c to be a habitable planet," Xavier Bonfils, of France's Joseph Fourier University-Grenoble, told SPACE.com by email.
He went on to caution that several possible uninhabitable combinations exist as well."
