Lam Cru is a rare variable star. It lies about 383.7 light-years from Earth, sits in the constellation Cru, shines at apparent magnitude 4.62 and has spectral type B4Vn.
Its spectrum reads B4Vn — 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 Lam Cru in the constellation Cru. At apparent magnitude 4.62, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, Lam Cru 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.
Lam Cru scores 39 points on Spacedle's rarity scale, which places it in the rare tier. Another 11 points would lift it into a rarer tier.
That score comes from 8 science badges — Variable star, Naked-eye visible, Under the Southern Cross, Hot blue B-type star, Main-sequence 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.
