HR 3413 is an uncommon variable star. It lies about 446.2 light-years from Earth, sits in the constellation Vel, shines at apparent magnitude 5.79 and has spectral type B8 Si.
Its spectrum reads B8 Si — a blue-white B-type star, with a surface tens of thousands of degrees hot and a life measured in tens of millions of years.
Look for HR 3413 in the constellation Vel. At apparent magnitude 5.79, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, HR 3413 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 3413 scores 29 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 5 points would lift it into a rarer tier.
That score comes from 6 science badges — Variable star, Naked-eye visible, Hot blue B-type star, Blue-white star, 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.
