V450 Aquilae is semi-regular pulsating star in the constellation Aquila. Located around 660 light-years distant, it shines with a luminosity approximately 2,172 times that of the Sun and has a surface temperature of 3,326 K.[3] The star varies in brightness from magnitude from 6.14 to 6.86,[4] so when it is at its brightest, it will be faintly visible to the naked eye.

Cuno Hoffmeister announced that V450 Aquilae was a newly discovered variable star in 1935.[5] Its period is 64.2 days.[4]
