c Puppis, also known as HD 63032 and HR 3017, is a spectroscopic binary star[3] in the constellation Puppis. Its apparent magnitude is of 3.61,[2] making it the eight-brightest star in Puppis. The system is the brightest member of the open cluster NGC 2451, over two magnitudes brighter than every other star in the cluster. As the turnoff point of the cluster is currently around B7, the parameters of the system fit with cluster membership.[10]

The primary component of the system is a red supergiant or bright giant of spectral classification K2.5Ib-IIa.[3] It is twelve times more massive than the Sun, and is estimated 16 million years old.[7] At this evolutionary stage, it has expanded to 280 times the size of the Sun[8] and is 15,000 more luminous. Its surface has cooled to an effective temperature of 3,781 K,[9] giving it a red-orange hue.[11] The secondary component is a late B-type star, about two times the size of the Sun. c Puppis was first discovered to be a spectroscopic binary in 1982, by D. Groote and D. Reimers.[10]
