Alnair is a rare star. It lies about 101 light-years from Earth, sits in the constellation Gru, shines at apparent magnitude 1.73 and has spectral type B7IV.
Its spectrum reads B7IV — 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 Alnair in the constellation Gru. At apparent magnitude 1.73, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, Alnair 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.
Alnair scores 35 points on Spacedle's rarity scale, which places it in the rare tier. Another 15 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, Subgiant (leaving the main sequence) 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.
