61 Virginis (abbreviated 61 Vir) is the Flamsteed designation of a G-type main-sequence star (G7V) slightly less massive than the Sun (which has a hotter G2V spectral type), located 27.8 light-years (8.5 parsecs) away in the constellation of Virgo. The composition of this star is nearly identical to the Sun.

61 Virginis (G7V) is the first well-established main-sequence star very similar to the Sun with a potential super-Earth,[9] though it was preceded by CoRoT-7 (a borderline orange dwarf).
