LHS 288 (Luyten 143-23) is a red dwarf star in the constellation Carina. At a distance of 15.759 light-years, it is among the nearest stars, and is the closest in the constellation.[10] Despite its distance, the star is far too faint to be seen with the unaided eye, with an apparent magnitude of 13.92.
The spectrum of this star matches a spectral class of M5V,[4] similar to the class of Proxima Centauri.[11] This star has an estimated 0.109 times the Sun's mass, 0.126 times the Sun's radius, and just 1.15% of the solar luminosity.[7] At an effective temperature of Script error: No such module "val".,[9] it radiates a reddish hue.[12]
A 2007 study suggested that LHS 288 may harbour a planet with a mass of 2.4 Template:Jupiter mass 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.[13]
