Its spectrum reads DAn... — a white dwarf — the exposed, Earth-sized cinder of a dead star, with nothing left to burn.
Look for HR 733 in the constellation For. At apparent magnitude 6.5, it is an easy target for binoculars.
Like any astronomical target, HR 733 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 733 scores 32 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 2 points would lift it into a rarer tier.
That score comes from 4 science badges — Variable star, White dwarf (a burnt-out core), 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.
