Look for 33The Cas in the constellation Cas. At apparent magnitude 4.34, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, 33The Cas 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.
33The Cas scores 22 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 12 points would lift it into a rarer tier.
That score comes from 5 science badges — Star, Naked-eye visible, 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.
