Location of LHS 288 in the constellation Carina |
LHS 288 (Luyten 143-23) is a red dwarf around 15.8 light years from the Sun, the closest in the constellation Carina (near Eta Carinae). It is far too faint to be seen with the unaided eye, with an apparent magnitude of 13.92.
Recent studies suggest it may harbour a planet with a mass as small as 2.4 |♃|J}}}}}}, but the possibility that it passed over an undetected faint star could not be eliminated.[5]
