Cor Caroli B is an uncommon star. It lies about 120.4 light-years from Earth, sits in the constellation CVn, shines at apparent magnitude 5.61 and has spectral type F0V.
Its spectrum reads F0V — an F-type star — a little hotter, whiter and shorter-lived than the Sun.
Look for Cor Caroli B in the constellation CVn. At apparent magnitude 5.61, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, Cor Caroli B 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.
Cor Caroli B scores 24 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 10 points would lift it into a rarer tier.
That score comes from 5 science badges — Star, Naked-eye visible, Has a proper name, 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.
