HD 31748 is a trash star. It lies about 644.6 light-years from Earth, sits in the constellation Eri, shines at apparent magnitude 9.5 and has spectral type A2V.
Its spectrum reads A2V — an A-type star: white-hot, typically about twice the Sun's mass, and the class most of the sky's famous bright stars belong to.
Look for HD 31748 in the constellation Eri. At apparent magnitude 9.5, a small backyard telescope will bring it into view.
Like any astronomical target, HD 31748 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.
HD 31748 scores 10 points on Spacedle's rarity scale, which places it in the trash tier. Another 5 points would lift it into a rarer tier.
That score comes from 3 science badges — Star, 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.
