Location of LHS 292 in the constellation Sextans

LHS 292 is a red dwarf star in the constellation Sextans. It is far too faint to be seen with the unaided eye and requires a large amateur telescope to be seen visually. It lies relatively close to the Solar System at a distance of about 14.9 light-years. It is a flare star, which means it can suddenly increase in brightness for short periods of time.

It has the space velocity components [U, V, W] = [28, −16, −14] km/s.[6]
