Eta Cru is an uncommon star. It lies about 64.4 light-years from Earth, sits in the constellation Cru, shines at apparent magnitude 4.14 and has spectral type F2III.
Its spectrum reads F2III — an F-type star — a little hotter, whiter and shorter-lived than the Sun.
Look for Eta Cru in the constellation Cru. At apparent magnitude 4.14, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, Eta 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.
Eta Cru scores 28 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 6 points would lift it into a rarer tier.
That score comes from 5 science badges — Star, Naked-eye visible, Under the Southern Cross, Yellow-white F-type star and Giant 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.
