Stellar association IC 142

IC 142 is a region of ionised hydrogen and a large stellar association in the Triangulum Galaxy. A stellar association is a very loose cluster of stars that share a common origin, but have become gravitationally unbound and are slowly moving apart. Associations are primarily identified by their common movement vectors and ages.

The region IC 142 was discovered on 28 October 1889 by astronomer Guillaume Bigourdan.
