HIP 9740 is an uncommon variable star. It lies about 2,117.9 light-years from Earth, sits in the constellation And, shines at apparent magnitude 9.01 and has spectral type A5.
Its spectrum reads A5 — 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 HIP 9740 in the constellation And. At apparent magnitude 9.01, a small backyard telescope will bring it into view.
Like any astronomical target, HIP 9740 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.
HIP 9740 scores 23 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 11 points would lift it into a rarer tier.
That score comes from 5 science badges — Variable star, Distant (over 1,000 light-years), White A-type star, Gently variable and A named variable 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.
