110 Virginis is a star in the zodiac constellation Virgo, located 195 [1] light-years away from the Sun. It is visible to the naked eye as an orange-hued star with an apparent visual magnitude of 4.40. [2] The star is moving closer to the Earth with a heliocentric radial velocity of −16 km/s. [2]
The stellar classification of 110 Virginis is K0.5 IIIb Fe–0.5, [3] indicating that this is an evolved giant star with a mild underabundance of iron in its spectrum. At the age of 4.5 [2] billion years old, it belongs to a sub-category of giants called the red clump, which means it is on the horizontal branch and is generating energy through the helium fusion at its core. [7] Compared to the Sun, it has 167% [2] of the mass but has expanded to 11 times the size. [4] The enlarged photosphere has an effective temperature of 4,664 K [2] and is radiating 76 [2] times the Sun's luminosity.
