HIP 72691 is an uncommon variable star. It lies about 2,740.8 light-years from Earth, sits in the constellation Dra, shines at apparent magnitude 11.8 and has spectral type A8.
Its spectrum reads A8 — 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 72691 in the constellation Dra. At apparent magnitude 11.8, a small backyard telescope will bring it into view.
Like any astronomical target, HIP 72691 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 72691 scores 33 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 1 point would lift it into a rarer tier.
That score comes from 6 science badges — Variable star, Distant (over 1,000 light-years), 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.
