HR 618 is a rare variable star. It sits in the constellation Per, shines at apparent magnitude 5.66 and has spectral type A1Ia.
Its spectrum reads A1Ia — 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 618 in the constellation Per. At apparent magnitude 5.66, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, HR 618 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 618 scores 43 points on Spacedle's rarity scale, which places it in the rare tier. Another 7 points would lift it into a rarer tier.
That score comes from 6 science badges — Variable star, Naked-eye visible, White A-type star, Supergiant, Gently variable 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.
