NGC 7822 is a young star-forming complex in the constellation of
Cepheus. 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,
[5][6] with the younger components aged no more than a few million years.
[5][6] 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 45,000 K and a luminosity about 100,000 times that of the Sun.
[5] 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.
