LHS 292

LHS 292 is a red dwarf 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 our star 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.
