61 Virginis (abbreviated 61 Vir) is a G5V class star slightly less massive than the Sun (G2V), located about 27.8 light-years away in the constellation of Virgo. The composition of this star is nearly identical to the Sun.
There is only a low level of activity in the stellar chromosphere. But the star was suspected as variable in 1988, and there was a burst of activity between Julian Day "54800" (29 November 2008) and "55220" (23 January 2010).
This star is rotating once every 29 days at the equator. The space velocity components of this star are U = –37.9, V = –35.3 and W = –24.7 km/s. 61 Vir is orbiting through the Milky Way galaxy at a distance of 6.9 kpc from the core, with an eccentricity of 0.15. It is believed to be a disk star with an estimated age of more than six billion years.
61 Virginis (G5V) is the first well established main sequence yellow dwarf star very similar to the Sun with a potential Super-Earth, though COROT-7 (a borderline orange dwarf) is arguably the first.
