Gliese 1062 (often GJ 1062) is a single[6] red dwarf star in the constellation Eridanus, positioned about two degrees to the SSE of Epsilon Eridani.[9] It is also known as LHS 20 and Ross 578\. The star is invisible to the naked eye with an apparent visual magnitude of +13.0,[2] requiring a telescope with at least a 25 cm (10 in) aperture to view.[10] It is located at a distance of 52.7 light years from the Sun based on parallax, but is drifting closer with a radial velocity of −85 km/s.[1] The star has a high proper motion, traversing the sky at the rate of 3.033 arcseconds per year.[11]

This is an M-type subdwarf star with a stellar classification of M2.5VI.[3] It was one of the first three subdwarfs to be definitively identified by G. Kuiper in 1940, the other two being Kapteyn's Star and Wolf 1106.[12] GJ 1062 is considered a likely member of the halo population, and thus is a MACHO.[13]
