Alpha Aquilae, also known as Altair, is the brightest star in the constellation Aquila. It is approximately 16.7 light-years away from Earth and is classified as a type A main-sequence star. Altair is notable for its rapid rotation, completing a full spin in about 10 hours, which causes it to have an oblate shape. As one of the closest stars visible to the naked eye, Altair is part of the Summer Triangle, along with Vega and Deneb. It has a surface temperature of around 7,500 Kelvin, making it significantly hotter than our Sun. Altair's brightness and position in the sky make it a prominent feature during summer nights.
