HR 1561 is an uncommon star. It lies about 423 light-years from Earth, sits in the constellation Cam, shines at apparent magnitude 5.75 and has spectral type A2Vs.
Its spectrum reads A2Vs — an A-type star: white-hot, typically about twice the Sun's mass, and the class most of the sky's famous bright stars belong to.
Look for HR 1561 in the constellation Cam. At apparent magnitude 5.75, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, HR 1561 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.
HR 1561 scores 22 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 12 points would lift it into a rarer tier.
That score comes from 5 science badges — Star, Naked-eye visible, Never sets (northern circumpolar), 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.
