Achernar is a trash variable star. It lies about 139.4 light-years from Earth, sits in the constellation Eri, shines at apparent magnitude 0.45 and has spectral type B3Vp.
Notable enough to have earned a proper name, not just a catalogue number.
Look for Achernar in the constellation Eri. At apparent magnitude 0.45, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, Achernar 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.
Achernar scores 13 points on Spacedle's rarity scale, which places it in the trash tier. Another 2 points would lift it into a rarer tier.
That score comes from 2 science badges — Variable star and Has a proper name — 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.
