description Sh2-68 Overview
Sh2-68 is a faint planetary nebula in the constellation Serpens. Its unusual appearance includes a compact, brighter region and a long, diffuse tail, giving it a comet-like form. This structure is interpreted as the result of the nebula's motion through the surrounding interstellar medium, which compresses material on its leading side and distorts the older, expanding gas behind it.
