}}{{Starbox end}}36 Aquilae (abbreviated 36 Aql) is a star in the equatorial constellation of Aquila. 36 Aquilae is its Flamsteed designation though it also bears the Bayer designation e Aquilae. With an apparent visual magnitude of 5.02,[3] this star is faintly visible to the naked eye. It has an annual parallax shift of 6.17 mas, indicating a physical distance of {{Convert|530|ly|pc|abbr=off|lk=on}} with a 30 light-year margin of error.The spectrum of this star matches a stellar classification of M1 III.[4] It is a red giant star with 54[11] times the radius of the Sun that is currently on the asymptotic giant branch.[17] This means the star is generating energy by the fusion of hydrogen along an outer shell and helium along a concentric inner shell, surrounding an inert core of carbon and oxygen. 36 Aquilae undergoes small, periodic variations in luminosity, changing by 0.0063 magnitudes about 11.5 times per day, or once every 2 hours and 5.2 minutes.[18] References1. ^1 {{citation | display-authors=1 | last1=Famaey | first1=B. | last2=Pourbaix | first2=D. | last3=Frankowski | first3=A. | last4=van Eck | first4=S. | last5=Mayor | first5=M. | last6=Udry | first6=S. | last7=Jorissen | first7=A. | title=Spectroscopic binaries among Hipparcos M giants.
