HIP 89990 is a trash star. It lies about 1,000.5 light-years from Earth, sits in the constellation Oph, shines at apparent magnitude 9.4 and has spectral type F2.
Its spectrum reads F2 — an F-type star — a little hotter, whiter and shorter-lived than the Sun.
Look for HIP 89990 in the constellation Oph. At apparent magnitude 9.4, a small backyard telescope will bring it into view.
Like any astronomical target, HIP 89990 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 89990 scores 12 points on Spacedle's rarity scale, which places it in the trash tier. Another 3 points would lift it into a rarer tier.
That score comes from 3 science badges — Star, Distant (over 1,000 light-years) and Yellow-white F-type 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.
