HD 30963 is a star in theconstellation ofEridanus. With anapparent magnitude of 7.23,[2] it cannot be seen with the naked eye.Parallax measurements put the star at a distance of around 1,022 light-years (313 parsecs).
HD 30963 is a lateB-type star.[3] It is amercury-manganese star,[3] a class ofchemically peculiar star that has an overabundance of certain elements likemercury. HD 30963 has 150,000 times as much mercury, 2,500 times as muchplatinum, 1,000 times as muchyttrium, and 150 times as muchzirconium compared to theSun.[3] It has a mass of 3.3 M☉, and its surface temperature is about11,500 K.
HD 30963 is close to the orbit that theSolar System is traversing in the Milky Way. The Sun will be close to the current location of HD 30963 in about 18.5 million years. Interstellar absorption lines for Na I are present for velocities lower than 10 km/s.[6][clarification needed]
