3 UMi is a trash star. It lies about 426.9 light-years from Earth, sits in the constellation UMi, shines at apparent magnitude 6.43 and has spectral type A7V.
Its spectrum reads A7V — 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 3 UMi in the constellation UMi. At apparent magnitude 6.43, it is an easy target for binoculars.
Like any astronomical target, 3 UMi 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.
3 UMi scores 14 points on Spacedle's rarity scale, which places it in the trash tier. Another 1 point would lift it into a rarer tier.
That score comes from 4 science badges — Star, Never sets (northern circumpolar), White A-type star and Main-sequence 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.
