1 Mon is a rare variable star. It lies about 294.6 light-years from Earth, sits in the constellation Mon, shines at apparent magnitude 6.15 and has spectral type F2IV.
Its spectrum reads F2IV — an F-type star — a little hotter, whiter and shorter-lived than the Sun.
Look for 1 Mon in the constellation Mon. At apparent magnitude 6.15, it is an easy target for binoculars.
Like any astronomical target, 1 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.
1 Mon scores 36 points on Spacedle's rarity scale, which places it in the rare tier. Another 14 points would lift it into a rarer tier.
That score comes from 6 science badges — Variable star, Yellow-white F-type star, Subgiant (leaving the main sequence), Gently variable, Fades out of naked-eye view 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.
