NGC 2392 is a bright planetary nebula that is known as the Eskimo or Clown Face nebula. It is located 2.3 degrees southeast of Wasat (Delta Geminorum) in the constellation of Gemini.

The 9.1-magnitude Eskimo nebula lies 3,000 light-years away and has an apparent size of 48 x 42 arcseconds, which is 1 light-year in space in real size. The white dwarf central star shines at magnitude 10.5.

The Eskimo is a complex double-shelled planetary nebula. The progenitor star is surrounded by two shells of gas ejected by the star.

NGC 2392 was discovered by William Herschel in 1787.
