HD 100364 is a common star. It lies about 2,077.4 light-years from Earth, sits in the constellation Crt, shines at apparent magnitude 9.41 and has spectral type A7IV.
Its spectrum reads A7IV — 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 100364 in the constellation Crt. At apparent magnitude 9.41, a small backyard telescope will bring it into view.
Like any astronomical target, HD 100364 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 100364 scores 19 points on Spacedle's rarity scale, which places it in the common tier. Another 3 points would lift it into a rarer tier.
That score comes from 4 science badges — Star, Distant (over 1,000 light-years), White A-type star and Subgiant (leaving the main sequence) — 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.
