SIMBAD data

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]

A loose agglomerate of stars around P Puppis was identified in 2008 as a young open cluster. Ten member stars were identified, including P Puppis itself and the naked-eye stars QS Puppis and HD 63578. [9] The cluster is part of the Vela OB2 association and at least 32 members have since been identified. It is thought that the cluster is only about 10 million years old. [10]
