Astronomers have discovered a giant new kind of planet that could hold life — and they could change everything
A super-Earth is a planet that is more massive and larger than Earth, although still made of rocks — perhaps with continents and oceans — and an atmosphere. There is no such planet in our Solar System, but we know that they must be common in other planetary systems.
Moreover, theory predicts that they might have all the nice attributes of Earth, and, in fact, provide a more stable environment on their surface. True super-Earths!
