HD 30963 is a late B-type star. It is a mercury-manganese star, a class of chemically peculiar star that has an overabundance of certain elements like mercury. HD 30963 has 150,000 times as much mercury, 2,500 times as much platinum, 1,000 times as much yttrium, and 150 times as much zirconium compared to the Sun. It has a mass of 2.90 M☉, and its surface temperature is about 11,500 K.
HD 30963 is close to the orbit that the solar 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.This article uses material from the Wikipedia article "HD 30963", which is released under the Creative Commons Attribution-Share-Alike License 3.0.
