Aldulfin is a rare star. It lies about 330.5 light-years from Earth, sits in the constellation Del, shines at apparent magnitude 4.03 and has spectral type B6III.
Its spectrum reads B6III — a blue-white B-type star, with a surface tens of thousands of degrees hot and a life measured in tens of millions of years.
Look for Aldulfin in the constellation Del. At apparent magnitude 4.03, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, Aldulfin 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.
Aldulfin scores 36 points on Spacedle's rarity scale, which places it in the rare tier. Another 14 points would lift it into a rarer tier.
That score comes from 6 science badges — Star, Naked-eye visible, Has a proper name, Hot blue B-type star, Giant star and Blue-white 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.
