It is one of the largest known stellar associations, along with Sagittarius OB5 and Cygnus OB2. It is much easier to see than that of the other associations since Carina OB1 has relatively little dust extinction in its region. Together with Carina OB2, they compromise the most massive stellar grouping known in the galaxy.
Carina OB1 is about 70 light-years (21 pc) across, and is the most massive stellar association in the Milky Way Galaxy since it lies within an active emission nebula. It contains many hot luminous stars which share common characteristics.
