HIP 78891 is an uncommon variable star. It lies about 751.5 light-years from Earth, sits in the constellation Dra, shines at apparent magnitude 10.69 and has spectral type A3.
Its spectrum reads A3 — 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 HIP 78891 in the constellation Dra. At apparent magnitude 10.69, a small backyard telescope will bring it into view.
Like any astronomical target, HIP 78891 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.
HIP 78891 scores 27 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 7 points would lift it into a rarer tier.
That score comes from 5 science badges — Variable star, Never sets (northern circumpolar), White A-type star, Strongly 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.
