Caph is a rare variable star. It lies about 54.7 light-years from Earth, sits in the constellation Cas, shines at apparent magnitude 2.28 and has spectral type F2III-IV.
Its spectrum reads F2III-IV — an F-type star — a little hotter, whiter and shorter-lived than the Sun.
Look for Caph in the constellation Cas. At apparent magnitude 2.28, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, Caph 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.
Caph scores 39 points on Spacedle's rarity scale, which places it in the rare tier. Another 11 points would lift it into a rarer tier.
That score comes from 8 science badges — Variable star, Naked-eye visible, Has a proper name, Never sets (northern circumpolar), Yellow-white F-type star, Giant star, Barely variable (under 0.05 mag) 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.
