HIP 81020 is a common star. It sits in the constellation Oph, shines at apparent magnitude 10.28 and has spectral type K5V.
Its spectrum reads K5V — a K-type star. Orange K dwarfs are the marathon runners of the galaxy, burning steadily for tens of billions of years.
Look for HIP 81020 in the constellation Oph. At apparent magnitude 10.28, a small backyard telescope will bring it into view.
Like any astronomical target, HIP 81020 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 81020 scores 16 points on Spacedle's rarity scale, which places it in the common tier. Another 6 points would lift it into a rarer tier.
That score comes from 4 science badges — Star, Orange K-type star, Main-sequence star and Deep red 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.
