55Eta Aql is an epic variable star. It lies about 1,382 light-years from Earth, sits in the constellation Aql, shines at apparent magnitude 3.87 and has spectral type F6Ibv SB.
Its spectrum reads F6Ibv SB — an F-type star — a little hotter, whiter and shorter-lived than the Sun.
Look for 55Eta Aql in the constellation Aql. At apparent magnitude 3.87, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, 55Eta Aql 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.
55Eta Aql scores 63 points on Spacedle's rarity scale, which places it in the epic tier. Another 15 points would lift it into a rarer tier.
That score comes from 8 science badges — Variable star, Distant (over 1,000 light-years), Naked-eye visible, Yellow-white F-type star, Supergiant, Intrinsically luminous (Mv < −2), Strongly 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.
