NGC 6337 is a small bipolar planetary nebula, also known as the Cheerio Nebula in the constellation of Scorpius. It is situated within a background field of ionized hydrogen nebulosity. The distance to this nebula is about 5.200 light-years.
Planetary nebula arise from the evolution of smaller stars (several solar masses) that end up as a white dwarf. In the case of NGC 6337 a central binary pair of stars is involved. The nebula shows several radial outflows and a faint halo.
