NGC 7822 represents a region of active star formation and includes the young open cluster Berkeley 59 at the western tip of the nebula with many of the member stars estimated to be only a few million years-old. NGC 7822 lies at a distance of 2,600 to 3,300 light-years away and spans approximately 30 light-years and 90 arc-minutes in diameter (equivalent to three full moons) and another 20 arc-minutes high. The nebula is believed to be illuminated by one of the brightest stars closest to the sun known, namely BD+66 1673, and whose surface temperature is approximately 45,000 degrees Kelvin.
