HD 33637 is an uncommon star. It lies about 1,045.4 light-years from Earth, sits in the constellation Ori, shines at apparent magnitude 9.77 and has spectral type A3V.
Its spectrum reads A3V — 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 33637 in the constellation Ori. At apparent magnitude 9.77, a small backyard telescope will bring it into view.
Like any astronomical target, HD 33637 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 33637 scores 22 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 12 points would lift it into a rarer tier.
That score comes from 5 science badges — Star, Distant (over 1,000 light-years), In Orion's hunting ground, 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.
