HIP 57731 is an uncommon variable star. It lies about 207.6 light-years from Earth, sits in the constellation UMa, shines at apparent magnitude 11.29 and has spectral type M0V.
Its spectrum reads M0V — 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 57731 in the constellation UMa. At apparent magnitude 11.29, a small backyard telescope will bring it into view.
Like any astronomical target, HIP 57731 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 57731 scores 29 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 5 points would lift it into a rarer tier.
That score comes from 7 science badges — Variable star, Never sets (northern circumpolar), Cool red M-type star, Main-sequence star, Red dwarf, 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.
