HIP 40178 is an uncommon variable star. It lies about 2,380.7 light-years from Earth, sits in the constellation Pup, shines at apparent magnitude 8.16 and has spectral type F9.
Its spectrum reads F9 — an F-type star — a little hotter, whiter and shorter-lived than the Sun.
Look for HIP 40178 in the constellation Pup. At apparent magnitude 8.16, it is an easy target for binoculars.
Like any astronomical target, HIP 40178 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 40178 scores 27 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 7 points would lift it into a rarer tier.
That score comes from 5 science badges — Variable star, Distant (over 1,000 light-years), Yellow-white F-type 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.
