PU Puppis (PU Pup) is a class B8III[3] (blue giant) star in the constellation Puppis. Its apparent magnitude is 4.69[2] and it is approximately 620 light years away based on parallax.[1]

A light curve for PU Puppis, plotted from TESS data[9]

It is a β Lyrae variable, ranging from 4.75 to 4.69 magnitude with a period of 2.58 days.[5] The secondary is estimated at about 5.6 magnitude, although recent observations have failed to confirm it.[10][11] The primary has a mass of 4.10 solar masses, and is radiating at an effective temperature of 11,500 K. The secondary, with a mass 65% that of the Sun, has a surface temperature of about 5,000 K.[7]
