Iot TrA is an uncommon variable star. It lies about 126.6 light-years from Earth, sits in the constellation TrA, shines at apparent magnitude 5.28 and has spectral type F4IV.
Its spectrum reads F4IV — an F-type star — a little hotter, whiter and shorter-lived than the Sun.
Look for Iot TrA in the constellation TrA. At apparent magnitude 5.28, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, Iot TrA 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.
Iot TrA 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 6 science badges — Variable star, Naked-eye visible, Yellow-white F-type star, Subgiant (leaving the main sequence), Gently variable 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.
