}}{{Starbox end}}AW Canum Venaticorum is a variable star[4] in the constellation Canes Venatici. It is visible to the naked eye with a nominal apparent visual magnitude of 4.76.[3] The distance to this star, as measured from its annual parallax shift of {{Val|5.3|ul=mas}},[1] is around 620 light years. It is moving closer with a heliocentric radial velocity of −44 km/s.[3]At the age of 1.1 billion years,[13] this is an evolved red giant star with a stellar classification of M3- IIIa.[5] It is a slow irregular variable of type Lb, with a brightness that ranges between magnitudes 4.73 and 4.85.[4] The star has 2.2[13] times the mass of the Sun and has expanded to 117[13] times the Sun's radius. It is radiating 2,387[13] times the Sun's luminosity from its enlarged photosphere at an effective temperature of 3,529 K.[16]
