The complex encompasses the emission region designated Sharpless 171, and the young cluster of stars named Berkeley 59.
The complex is believed to be some 800-1000 pc distant (3,000 light years), with the younger components aged no more than a few million years.
The complex also includes one of the hottest stars discovered within 1 kpc of the Sun, namely BD+66 1673, which is an eclipsing binary system consisting of an O5V that exhibits a surface temperature of nearly 45000 K and a luminosity ~100,000 times that of the Sun.
The star is one of the primary sources illuminating the nebula and shaping the complex’s famed pillars of creation-type formations, the elephant trunks.
