Notes	A hot giant star in Monoceros, a few degrees eastward of the feet of Orion. The primary of this system is some three times the diameter of the Sun, and is known to be a spectroscopic binary: variations in its spectrum reveal an orbiting companion star.

The slightly fainter star to the north of 2 Monocerotis is the pulsating variable 1 Monocerotis. These two stars are relatively close neighbours in space, lying a little over twenty light years from one another. Imagery provided by Aladin sky atlas
