Star in the constellation Eridanus
GJ 1062 is a single[ 6] red dwarf star in theconstellation Eridanus , positioned about two degrees to the SSE ofEpsilon Eridani .[ 9] LHS 20 andRoss 578. The star is invisible to the naked eye with anapparent visual magnitude of +13.0,[ 2] aperture to view.[ 10] light years from theSun based onparallax , but is drifting closer with aradial velocity of −85 km/s.[ 1] proper motion , traversing the sky at the rate ofarcseconds [ 11]
This is anM-type subdwarf star with astellar classification of M2.5VI.[ 3] G. Kuiper in 1940, the other two beingKapteyn's Star andWolf 1106 .[ 12] halo population, and thus is aMACHO .[ 13]
