Gliese 1062 is a M-type subdwarf star in the constellation Eridanus.[5] [7] The star has a total proper motion of 3.033 "/yr, making it the 25th fastest-moving star in terms of angular position as seen from Earth, and its radial velocity is -18 km/s. At a distance of about 52 light years (16 parsecs) and with an absolute magnitude of 13.1, this star has an apparent magnitude of 14.6 when viewed from Earth.[8][9]

The star is also known as LHS 20 and Ross 578.
