Description

Although not commonly photographed, Sh2-216 (aka Simeis 288) is a fascinating object shown in this image. Sh2-216 is not only the closest planetary nebula to us, it also appears as the largest planetary nebula in our sky. With an apparent diameter of 1.6 degrees, its large size in our sky is due to its close proximity - its only about 420 light years from our solar system.
