A modern constellation created in 1624 and credited to the German astronomer Jakob Bartsch. He used faint stars found between Canis Major and Canis Minor, and east of Orion.

But Monoceros does have something interesting to see with the aid of a small telescope. Beta Monocerotis is an impressive triple star system, the three stars form a triangle which seems to be fixed. The visual magnitudes of the stars are 4.7, 5.
