HD 63922 is a class B0III [3] (blue giant) star in the constellation Puppis. Its apparent magnitude is 4.11 [2] and it is approximately 1600 light years away based on parallax. [1]
It is a multiple star; the primary has one close companion, Ab, at 0.3" separation and magnitude 7.19, and a more distant one, B, at 59.1" and 8.79 magnitude. [8]
