HIP 91316 is a rare variable star. It lies about 3,106.2 light-years from Earth, sits in the constellation Dra, shines at apparent magnitude 9.46 and has spectral type M5e.
Its spectrum reads M5e — an M-type red star — and M stars are the silent majority: roughly three of every four stars in the galaxy are one.
Look for HIP 91316 in the constellation Dra. At apparent magnitude 9.46, a small backyard telescope will bring it into view.
Like any astronomical target, HIP 91316 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 91316 scores 39 points on Spacedle's rarity scale, which places it in the rare tier. Another 11 points would lift it into a rarer tier.
That score comes from 7 science badges — Variable star, Distant (over 1,000 light-years), Never sets (northern circumpolar), Cool red M-type star, Red dwarf, 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.
