Westerhout 3 is a young star located approximately 6,000 light-years away in the constellation Cassiopeia. It is part of a group of stars known as OB associations, which are characterized by their high mass and brightness. This star is particularly interesting because it is surrounded by a large cloud of gas and dust, which is a region where new stars can form. The study of Westerhout 3 helps astronomers understand the processes of star formation and the evolution of stellar systems in our galaxy, the Milky Way.
