About
TRAPPIST-1e is one of seven Earth-sized planets orbiting a small red dwarf 40 light-years away. It is slightly smaller than Earth, rocky, and orbits where liquid water could exist on its surface. Its look here is an artist's impression.
One of the most promising places to look for liquid water beyond the Solar System.
