Castula is a rare star. It lies about 199.9 light-years from Earth, sits in the constellation Cas, shines at apparent magnitude 4.62 and has spectral type G8III-IV.
Its spectrum reads G8III-IV — a G-type star: the very same spectral class as our own Sun.
Look for Castula in the constellation Cas. At apparent magnitude 4.62, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, Castula 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.
Castula scores 37 points on Spacedle's rarity scale, which places it in the rare tier. Another 13 points would lift it into a rarer tier.
That score comes from 6 science badges — Star, Naked-eye visible, Has a proper name, Never sets (northern circumpolar), Sun-like G-type star and Giant 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.
