HIP 20993 is a rare variable star. It lies about 2,718 light-years from Earth, sits in the constellation Per, shines at apparent magnitude 8.28 and has spectral type M2.
Its spectrum reads M2 — an M-type red star — and M stars are the silent majority: roughly three of every four stars in the galaxy are one.
Look for HIP 20993 in the constellation Per. At apparent magnitude 8.28, it is an easy target for binoculars.
Like any astronomical target, HIP 20993 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 20993 scores 37 points on Spacedle's rarity scale, which places it in the rare tier. Another 13 points would lift it into a rarer tier.
That score comes from 7 science badges — Variable star, Distant (over 1,000 light-years), Cool red M-type star, Deep red star, Red dwarf, 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.
