The Homunculus Nebula is a bipolar emission and reflection nebula surrounding the massive star system Eta Carinae, about 7,500 light-years (2,300 parsecs) from Earth. The nebula is embedded within the much larger Carina Nebula, a large star-forming H II region.

The Homunculus consists of two lobes, referred to as NW and SE based on their orientation as seen from Earth, each approximately 7″ wide by 5″ long. There is also a ragged equatorial skirt of material which can be seen faintly in deep images at certain wavelengths. The lobes are mostly hollow with the material strongly concentrated towards the poles.
