Its spectrum reads F3p — an F-type star — a little hotter, whiter and shorter-lived than the Sun.
Look for Eta Sco in the constellation Sco. At apparent magnitude 3.32, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, Eta Sco 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 Sco scores 17 points on Spacedle's rarity scale, which places it in the common tier. Another 5 points would lift it into a rarer tier.
That score comes from 4 science badges — Star, Naked-eye visible, On the zodiac and Yellow-white F-type 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.
