Beschreibung:
In terms of angular size Sh2-216 is the largest planetary nebulae in the sky, being about 3x wider than the moon as seen from earth, although it is too faint to be seen. It is about 500 000 years old, explaining why it is so very large and very dim. Sh2-216 is also the second closest planetary nebula at a distance of 400 light years.
