HEC_All_Confirmed_Gliese667C

No one knows what the planet Gliese 667Cc looks like. We know that it is about 22 light-years from Earth, a journey of lifetimes upon lifetimes. The planet is bigger than our world, perhaps made of rocks instead of gas, and within its star’s “habitable zone” – at a Goldilocks distance that ensures enough starlight to make liquid water possible but not so much as to nuke the planet clean.
