Its spectrum reads F2V — an F-type star — a little hotter, whiter and shorter-lived than the Sun.
Look for HR 4686 in the constellation UMi. At apparent magnitude 6.27, it is an easy target for binoculars.
Like any astronomical target, HR 4686 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.
HR 4686 scores 19 points on Spacedle's rarity scale, which places it in the common tier. Another 3 points would lift it into a rarer tier.
That score comes from 6 science badges — Variable star, Never sets (northern circumpolar), Yellow-white F-type star, Main-sequence star, Barely variable (under 0.05 mag) 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.
