110 Virginis is a star in the zodiac constellation Virgo, located 195[1] light-years away from Earth. 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.[1]
The stellar classification of 110 Virginis is K0.5 IIIb Fe–0.5,[4] 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.[3] Compared to the Sun, it has 167%[2] of the mass but has expanded to 14 times the size. The enlarged photosphere has an effective temperature of 4,655 K and is radiating 80 times the Sun's luminosity.[5]
