10 Aquilae (abbreviated 10 Aql) is a star in the equatorial constellation of Aquila. 10 Aquilae is the Flamsteed designation. It has an apparent visual magnitude of 5.9[2] and thus is a faint star that is just visible to the naked eye in dark skies. The brightness of this star is diminished by 0.17 in visual magnitude from extinction caused by interstellar gas and dust.[6] Based on an annual parallax shift of 13.45 mas, the distance to this star is around 240 light-years (74 parsecs).
The outer envelope of this star has an effective temperature of 8,659 K,[6] giving it the yellow-white hued glow of an F-type star.[9] It is a type of chemically peculiar star known as an Ap star, as indicated by the 'p' in the stellar classification. Because it is a pulsating variable star, it belongs to a sub-group known as rapidly oscillating Ap stars.[5]
