HIP 15811 is an uncommon variable star. It lies about 474.1 light-years from Earth, sits in the constellation Per, shines at apparent magnitude 10.53 and has spectral type F0V.
Its spectrum reads F0V — an F-type star — a little hotter, whiter and shorter-lived than the Sun.
Look for HIP 15811 in the constellation Per. At apparent magnitude 10.53, a small backyard telescope will bring it into view.
Like any astronomical target, HIP 15811 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 15811 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, Yellow-white F-type star, Main-sequence star, Strongly 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.
