Sh 2-71 is a Planetary Nebula in Aquila.
It was discovered by Rudolph Minkowski in 1946. It was cataloged by Stewart Sharpless in 1959, who thought it was a possible planetary nebula. In 1961, it was confirmed as a planetary nebula by Boris Vorontsov-Velyaminov.[1]
The center of the nebula contains a binary star system, however it is believed the shape and structure of the nebula is formed partially because of a triple star system that has since ejected its third member.[2][3] Only one planetary nebula with an intact triple star system is know, being NGC 246.
