69 Virginis is a single star in the zodiac constellation of Virgo, located about 259 light years away. It is visible to the naked eye as a faint orange-hued star with an apparent visual magnitude of 4.76, although it is a suspected variable that may range in magnitude from 4.75 down to 4.79. This object is moving closer to the Earth with a heliocentric radial velocity of −13 km/s. The light from this star is polarized due to intervening interstellar dust.
This is an evolved K-type giant star with a stellar classification of {{nowrap|K0 III-IIIb CN1.5 CH0.5}}, showing overabundances of CN and CH molecules in the spectrum. It is a red clump giant, which indicates is on the horizontal branch generating energy via helium fusion at its core. The star is about 288 million years old with 3.5 times the mass of the Sun and 15 times the Sun's radius. It is radiating 87 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,909 K.
