c Puppis, also known as HD 63032 and HR 3017, is a
spectroscopic binarystar[3] in the constellation
Puppis. Its apparent magnitude is 3.61.[2] Located around 347 parsecs (1,130 ly) distant, the primary is an orange-red
bright giant or supergiant of spectral type K2.5Ib-IIa or K5IIa,[3] while the secondary, discovered in 1983,[7] is a
blue main-sequence star of spectral type B9V.[3] The system is the brightest member of the
open clusterNGC 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.[7]
