TRAPPIST-1e
exoplanet
41 light-years from Earth
The most Earth-like of the seven: about Earth's size and density, in the zone where water could stay liquid. It probably keeps one side facing its star, as the Moon does with Earth.
- orbit 6.1 days at 0.02925 AU · 0.92 times Earth's width
- illustrative: the sea under its star and the ice around it are a guess; no one knows yet if it has air or water
