HR 5110 is an uncommon variable star. It lies about 148.9 light-years from Earth, sits in the constellation CVn, shines at apparent magnitude 4.91 and has spectral type F2IV SB.
Its spectrum reads F2IV SB — an F-type star — a little hotter, whiter and shorter-lived than the Sun.
Look for HR 5110 in the constellation CVn. At apparent magnitude 4.91, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, HR 5110 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 5110 scores 26 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 8 points would lift it into a rarer tier.
That score comes from 6 science badges — Variable star, Naked-eye visible, Yellow-white F-type star, Subgiant (leaving the main sequence), Barely variable (under 0.05 mag) 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.
