HR 3520 is a rare star. It lies about 1,109.4 light-years from Earth, sits in the constellation Vel, shines at apparent magnitude 4.94 and has spectral type A2III.
Its spectrum reads A2III — 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 3520 in the constellation Vel. At apparent magnitude 4.94, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, HR 3520 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 3520 scores 38 points on Spacedle's rarity scale, which places it in the rare tier. Another 12 points would lift it into a rarer tier.
That score comes from 6 science badges — Star, Distant (over 1,000 light-years), Naked-eye visible, White A-type star, Giant star and Intrinsically luminous (Mv < −2) — 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.
