The Canis-Minorids are a meteor shower that arise from the direction of the constellation Canis Minor.

The 11 Canis-Minorids, also called the Beta Canis Minorids,[1] are a meteor shower that arises near the fifth-magnitude star 11 Canis Minoris. They were discovered in 1964 by Keith Hindley, who investigated their trajectory and proposed a common origin with the comet D/1917 F1 Mellish.[2] However, this conclusion has been refuted subsequently as the number of orbits analysed was low and their trajectories too disparate to confirm a link.[3] They last from 4 to 15 December, peaking over 10 and 11 December.[4]
