22Eta Cap is an uncommon star. It lies about 161.5 light-years from Earth, sits in the constellation Cap, shines at apparent magnitude 4.82 and has spectral type A5V.
It is a binary: two stars orbiting a shared centre of mass. More than half of all the 'stars' you can see are actually multiple systems.
Look for 22Eta Cap in the constellation Cap. At apparent magnitude 4.82, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, 22Eta Cap 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.
22Eta Cap scores 27 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 7 points would lift it into a rarer tier.
That score comes from 6 science badges — Star, Naked-eye visible, Binary star, On the zodiac, White A-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.
