LHS 3844 b
LHS 3844 b is an exoplanet orbiting the star LHS 3844. It is 2.25 times as massive as Earth and its surface may resemble that of the Moon or Mercury. Its radius is 1.32 times that of Earth, and it probably does not have an atmosphere as close to no heat goes to its night side and it has a maximum temperature of 700 °C (1,292 °F).[2] It orbits its parent star once every 11 hours.[3]
