About this object
The Rosette Nebula is a large, circular emission nebula in the constellation Monoceros. It surrounds a cluster of hot, young stars known as the Rosette Cluster (NGC 2244). The Rosette is an H II region at a distance of some 5,200 light years, near one end of a large molecular cloud in Monoceros (though distance estimates vary considerably). Its diameter is about 130 light years, and the central hole is about 30 light years across. The nebula is estimated to contain around 10,000 solar masses.
