39 Com is a trash star. It lies about 162 light-years from Earth, sits in the constellation Com, shines at apparent magnitude 6 and has spectral type F4V.

Look for 39 Com in the constellation Com. At apparent magnitude 6, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, 39 Com 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.
39 Com scores 8 points on Spacedle's rarity scale, which places it in the trash tier. Another 7 points would lift it into a rarer tier.
That score comes from 3 science badges — Star, Yellow-white F-type star and Main-sequence 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.
