11 Aquilae (abbreviated 11 Aql) is a single[9] star in the equatorial constellation of Aquila. 11 Aquilae is the Flamsteed designation. It has an apparent visual magnitude of 5.2,[2] which means it is faintly visible to the naked eye. Based upon an annual parallax shift of 20.65 mas,[1] the distance to this star is approximately 158 light-years (48 parsecs). The brightness of this star is diminished by 0.33 in magnitude because of extinction from interstellar gas and dust.[6]
This is an F-type main sequence star with a stellar classification of F8 V.[3] It is radiating about 19[6] times the luminosity of the Sun from its outer atmosphere at an effective temperature of 6,074 K,[5] giving it the yellow-white glow of an F-type star.[10] 11 Aquilae has been listed as a candidate for membership in the Ursa Major Moving Group, but most likely does not belong to that association.[11]
