Its spectrum reads M6.5 — 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 HD 250530 in the constellation Ori. At apparent magnitude 10.09, a small backyard telescope will bring it into view.
Like any astronomical target, HD 250530 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.
HD 250530 scores 35 points on Spacedle's rarity scale, which places it in the rare tier. Another 15 points would lift it into a rarer tier.
That score comes from 6 science badges — Variable star, In Orion's hunting ground, Cool red M-type star, Red dwarf, 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.
