5 Lac is an epic star. It lies about 1,647.3 light-years from Earth, sits in the constellation Lac, shines at apparent magnitude 4.34 and has spectral type M0II.
Its spectrum reads M0II — 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 5 Lac in the constellation Lac. At apparent magnitude 4.34, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, 5 Lac 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.
5 Lac scores 52 points on Spacedle's rarity scale, which places it in the epic tier. Another 26 points would lift it into a rarer tier.
That score comes from 7 science badges — Star, Distant (over 1,000 light-years), Naked-eye visible, Cool red M-type star, Bright giant, Deep red star and Intrinsically luminous (Mv < −2) — 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.
