Sh2-285, also known as LBN 762, is a bright emission nebula located in the constellation of Cassiopeia. It is part of a larger complex of interstellar gas and dust, which is often associated with star formation. The nebula is approximately 1,000 light-years away from Earth and spans about 30 light-years across. This nebula is notable for its striking appearance, featuring a mix of red and blue hues due to the ionization of hydrogen gas by nearby young stars. Observations of Sh2-285 contribute to our understanding of the processes involved in stellar formation and the dynamics of interstellar medium.
