HD 71863 (HR 3346) is a solitary star in the southern circumpolar constellation Volans. It is faintly visible to the naked eye with an apparent magnitude of 5.94 and is located 408 light-years away based on parallax measurements. However, it is receding with a radial velocity of 19.1 km/s.

HD 71863 has a classification of G8/K0 III[3] — intermediate between a G8 and K0 giant star. It has 2.65 times the mass of the Sun but has expanded to 11 times it's girth.[7] It shines at 72 times the luminosity of the Sun[7] and rotates slowly, with a projected rotational velocity of 2.7 km/s.[8] With an effective temperature of 5,014 K,[7] it has a yellowish-orange hue. HD 71863 metallicity – elements heavier than helium – is at solar level.[7]

HD 71863 is located near a group of stars moving with a Carinae, but is just moving with them by coincidence, and has no relation to the group.[11]
