BU Canis Minoris is a binary star system in the equatorial constellation of Canis Minor. It has the "Henry Draper Catalogue" designation of HD 65241, while "BU Canis Minoris" is its variable star designation. The system is a challenge to view with the naked eye, having a peak apparent visual magnitude of 6.42. It is located at a distance of approximately 700 light years from the Sun based on parallax, and is drifting further away with a radial velocity of about +34 km/s.
This pair is a double-lined spectroscopic binary system that forms an Algol-like eclipsing binary. The brightness of the system decreases from 6.44 down to 6.53 during the primary eclipse. It has a stellar classification of A0V, which matches an A-type main-sequence star that is generating energy through hydrogen fusion at its core.
