Omega2 Aquilae

Omega2 Aquilae, Latinized from ω2 Aquilae, is the Bayer designation for a star in the equatorial constellation of Aquila, the eagle. It has an apparent visual magnitude of 6.0, which is close to the lower limit of detectability with the naked eye. According to the Bortle Dark-Sky Scale, this star can be viewed from dark rural skies. As the Earth orbits about the Sun, this star undergoes a parallax shift of $0.087$. This is equivalent to a physical distance of 279 ly from Earth, give or take a 2 light year margin of error. The star is drifting closer to the Sun with a radial velocity of −26 km/s.

Analysis of the spectrum of this white-hued star shows it to match a stellar classification of A2 V, indicating it is an A-type main sequence star. It has about double the size and mass of the Sun. The star is radiating 22 times the luminosity of the Sun from its photosphere at an effective temperature of 8,936 K, giving it the white hue of an A-type star. Omega2 Aquilae is 224 million years old and is spinning rapidly with a projected rotational velocity of 154 km/s.
