HIP 100818 is an uncommon star. It lies about 165.1 light-years from Earth, sits in the constellation Sgr, shines at apparent magnitude 11.58 and has spectral type M0.
Its spectrum reads M0 — 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 100818 in the constellation Sgr. At apparent magnitude 11.58, a small backyard telescope will bring it into view.
Like any astronomical target, HIP 100818 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 100818 scores 25 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 9 points would lift it into a rarer tier.
That score comes from 5 science badges — Star, Toward the galactic centre, On the zodiac, Cool red M-type star and Red dwarf — 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.
