6 Canum Venaticorum is a single [8] star in the northern constellation Canes Venatici, located 246 light years from the Sun. [1] It is visible to the naked eye as a faint yellow-hued star with an apparent visual magnitude of +5.01. [2] The star is moving closer to the Earth with a heliocentric radial velocity of −4.2 km/s. [5]
This is an evolved G-type giant star with a stellar classification of G9 III, [4] which means it has exhausted the hydrogen supply at its core and expanded. It is a red clump giant, indicating that it is on the horizontal branch and is generating energy through the helium fusion at its core. [3] Data from the Hipparcos mission provided evidence of microvariability with an amplitude of 0.0056 in magnitude and a frequency of 0.00636 per day, or one cycle every 157 days. [9]
6 Canum Venaticorum is about two [2] billion years old with double [2] the mass of the Sun. It has expanded to 9 [5] times the Sun's radius and is radiating 68 [2] times the Sun's luminosity from its photosphere at an effective temperature of 4,938 K. [2]
