p Puppis (HD 60863) is a star system the constellation Puppis. This system consists of a B8V^[3] (blue main-sequence) star and a secondary star at 7.4 AU, much smaller than the primary, as well as farther companions.^[6] Its apparent magnitude is 4.65^[2] and it is approximately 222 light years away based on parallax.^[1]

In addition to the inner pair, there are the distant companions HIP 36890, at apparent magnitude 7.83^[9] and projected separation of 38,700 AU, which is itself an astrometric binary, and a faint white dwarf at a distance of 1,300 AU. This make p Puppis a five-star system.^[6]
