LHS 3844 is a red dwarf star located 48.5 light-years (14.9 parsecs) away from the Solar System in the constellation of Indus. The star has about 15% the mass and 19% the radius of the Sun.[3] It is a relatively inactive red dwarf with a slow rotation period of about 128 days, though UV flares have been observed.[6] LHS 3844 is orbited by one known exoplanet.
