c Puppis is by far the brightest star in the region of the sky occupied by the composite cluster Collinder 161 or NGC 2451, which actually represents two unrelated clusters on the same line of sight from Earth. Based on its distance and spectral type, c Puppis appears to be an evolved member of the more distant of the two clusters, NGC 2451B. Imagery provided by Aladin sky atlas
