NGC 6337, the Ghostly Cheerio or Cheerio Nebula, is a toroidal planetary nebula in the constellation Scorpius. It appears as a ring-shaped (annular) transparent nebula resembling a piece of the breakfast cereal Cheerios, hence the name.

NGC 6337 is a small, bipolar planetary nebula (PNe), also known as the Cheerio Nebula, in the constellation of Scorpius at about 5,200 light years distant. It is situated within a field of backround hydrogen nebulosity. Planetary nebula arise from the evolution of smaller stars (0.8 – 8 solar masses) that end up as a white dwarf.
