NGC7662: NGC7662, also known as the Blue Snowball Nebula, is a small (about 2.2 arcminutes in diameter, including the very faint halo around the bright part of the nebula), bright (magnitude 9) planetary nebula, the type of nebula which it is generally thought our Sun will produce as nuclear fusion slows and then dies in its core, and it expels its outer layers of gas. Estimates of its distance from Earth vary, but tend to be around 4000 light years.
