The Cone Nebula is an H II region in the constellation of Monoceros. It was discovered by William Herschel on December 26, 1785. The nebula is located about 2,700 light-years away from Earth. The Cone Nebula forms part of the nebulosity surrounding the Christmas Tree Cluster. The designation of NGC refers to both objects and not the nebula alone.
