HD 70514, also known as HR 3280, is a solitary,[14] orange hued star located in the southern circumpolar constellation Volans, the flying fish. It has an apparent magnitude of 5.06,[2] making it one of the brighter members of this generally faint constellation. Based on parallax measurements from the Gaia spacecraft, the star is estimated to be 298 light years distant.[1] It appears that its distance to the Solar System isn't changing, having a heliocentric radial velocity of 0 km/s.[6] Eggen (1994) lists it as a member of the thin disk population.[11]

HD 70514 is classified as a red giant, having a stellar classification of K1 III. It is currently on the red giant branch, fusing a hydrogen shell around an inert helium. As a result, it has expanded to 14.6 times radius of the Sun[8] and now radiates 93 times its luminosity[1] from its enlarged photosphere at an effective temperature of 4,610 K.[10] Based on asteroseismologic measurements, HD 70514 has a mass 1.88 times that of the Sun.[3] HR 3280 is metal enriched, having a metallicity 66% above solar levels. Like most giants, it rotates rather slowly, having a projected rotational velocity of <1 km/s.[12]
