LHS 288 (Luyten 143-23) is a red dwarf star around 15.8 light-years from the Sun, the closest in the constellation Carina[8] (near Eta Carinae). It is far too faint to be seen with the unaided eye, with an apparent magnitude of 13.92.
A 2007 study suggested that LHS 288 may harbour a planet with a mass of 2.4 MJ based on astrometric observations, but the possibility that it passed over an undetected faint star, which could mimic the astrometric variation caused by a planet, could not be eliminated.[9][10]
