HD 64315 is a rare variable star. It lies about 2,861 light-years from Earth, sits in the constellation Pup, shines at apparent magnitude 9.19 and has spectral type A1Ia:p.
Its spectrum reads A1Ia:p — an A-type star: white-hot, typically about twice the Sun's mass, and the class most of the sky's famous bright stars belong to.
Look for HD 64315 in the constellation Pup. At apparent magnitude 9.19, a small backyard telescope will bring it into view.
Like any astronomical target, HD 64315 is best seen from a dark site away from city lights, and when it is above the horizon depends on your latitude and the time of year. The visibility panel above works out tonight's viewing window for your saved location.
HD 64315 scores 41 points on Spacedle's rarity scale, which places it in the rare tier. Another 9 points would lift it into a rarer tier.
That score comes from 6 science badges — Variable star, Distant (over 1,000 light-years), White A-type star, Supergiant, Gently variable and A named variable star — each earned for a real, measurable property of the object. Rarity on Spacedle is never random: the more remarkable an object's astrophysics, the more badges it collects, the higher it scores, and the rarer it ranks.
