NGC 7822 is a young star forming complex in the constellation of Cepheus. The complex is believed to be some 800-1000 pc distant with the younger components aged no more than a few million years. It also includes a very hot star that exhibits a surface temperature of nearly 45000 K and a luminosity ~100000 times that of our Sun. The star is one of the primary sources illuminating the nebula.
