BC Canis Minoris

BC Canis Minoris is a variable star in the equatorial constellation of Canis Minor. It has a reddish hue and is just barely visible to the naked eye with an apparent visual magnitude that fluctuates around 6.30. The distance to this object is approximately 568 light years based on parallax, but it is drifting closer with a radial velocity of −67 km/s.
In 1962, Alan William James Cousins announced that HR 3061 is a variable star. It was given its variable [star designation], BC Canis Minoris, in 1975. It is an aging red giant star currently on the asymptotic giant branch with a stellar classification of M4/5III. It is a semi-regular variable of subtype SRb with measured pulsation periods of 27.7, 143.3 and 208.3 days, and an average visual magnitude of 6.30. With the supply of hydrogen at its core exhausted, it has cooled and expanded off the main sequence and now has around 53 times the girth of the Sun. On average, the star is radiating about 559 times the luminosity of the Sunfrom its swollen photosphere at an effective temperature of 3,980 K.
