Another potential habitable planet found? If it is inhabited by life, it would be very strange compared to what we know considering the size of the planet and the energy it receives.

A potentially habitable planet has been discovered orbiting the star Gliese 163, 50 light-years away. The planet is bigger than Earth — roughly seven times as massive — and resides near the inner edge of the star’s habitable zone, Thierry Forveille of France’s Observatoire de Grenoble reported on August 30 at the International Astronomical Union’s general assembly meeting. Depending on its composition and how insulating its atmosphere is, the planet could be capable of supporting life.
“I’d say that’s a habitable planet,” said Raymond Pierrehumbert of the University of Chicago. It’s unlikely the planet would experience any sort of runaway greenhouse effect that would heat it beyond the point of livability, he says.
