NGC 2175 is an open star cluster surrounded by nebulosity in the constellation Orion. The star cluster is located directly behind the “eye” of the monkey head. The entire nebula consists of the following star clusters: NGC 2175, NGC 2175S, NGC 2174 and the nebula surrounding them. NGC 2175S, also known as Lund 1182, is located at the “base of the skull” of the monkey head. NGC 2174 is the star cluster located directly behind the “mouth” of the monkey head. The entire complex is commonly called the Monkey Head Nebula.
