13 Mon is a rare star. It sits in the constellation Mon, shines at apparent magnitude 4.47 and has spectral type A0Ib.
Its spectrum reads A0Ib — an A-type star: white-hot, typically about twice the Sun's mass, and the class most of the sky's famous bright stars belong to.
Look for 13 Mon in the constellation Mon. At apparent magnitude 4.47, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, 13 Mon 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.
13 Mon scores 34 points on Spacedle's rarity scale, which places it in the rare tier. Another 16 points would lift it into a rarer tier.
That score comes from 4 science badges — Star, Naked-eye visible, White A-type star and Supergiant — 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.
