NGC 2264 is the designation number of the
New General Catalogue that identifies two
astronomical objects as a single object:
Two other objects are within this designation but not officially included:
All of the objects are located in the
Monoceros constellation and are located about 800
parsecs or 2600
light-years from
Earth.
NGC 2264 is sometimes referred to as the Christmas Tree Cluster and the
Cone Nebula. However, the designation of NGC 2264 in the
New General Catalogue refers to both objects and not the cluster alone.
