Monoceros

Monoceros lies next to Orion on the band of the Milky Way, and so the area of space it describes is on the plane of our Galaxy. Much of the Milky Way visible in this constellation belongs to the Orion Arm of the Galaxy.

This relatively modern constellation (introduced in 1690) supposedly represents a unicorn. Though lacking in impressive stars, it is home to several star clusters and, especially noteworthy, the Rosette Nebula.
