The Rosette Nebula (Caldwell 49 or NGC 2237) is a large, circular H II region located in the constellation Monoceros . Open cluster's NGC 2244 (Caldwell 50) stars have been formed from the nebula's matter.

The Rosette Nebula consists of 5 parts NGC 2237,NGC 2238,NGC 2239,NGC 2244,NGC 2246. The cluster and nebula are about 5,000 light-years from Earth and measure roughly 130 light years in diameter. The nebula is estimated to be around 10,000 solar masses
