Round and planet-shaped, the nebula is also relatively faint. The high energy radiation from the central white dwarf causes the surrounding nebula to emit light. The nebula’s main ring structure is about a light-year across and the glow from ionized oxygen, hydrogen, and nitrogen atoms are colored blue, green, and red respectively.

The Little Ghost Nebula should not be confused with the Ghost Nebula (Sh2-136) or the Ghost Head Nebula (NGC 2080).
