Alkalurops is an uncommon star. It lies about 113.1 light-years from Earth, sits in the constellation Boo, shines at apparent magnitude 4.31 and has spectral type F0V.
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 Alkalurops in the constellation Boo. At apparent magnitude 4.31, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, Alkalurops 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.
Alkalurops scores 30 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 4 points would lift it into a rarer tier.
That score comes from 6 science badges — Star, Naked-eye visible, Binary star, Has a proper name, Yellow-white F-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.
