Bright Stars
Altair is the brightest star in Aquila with a magnitude of 0.76 making it one of the brightest stars in the night sky. Altair is part of the asterism known as the Summer Triangle (along with Deneb and Vega). Altair is relatively close to Earth at only 17 light-years distant. The second-brightest star is Tarazed, an orange-hued giant star of around magnitude 2.7. Okab is a binary star of magnitude 3.0. The companion star is much fainter at 12th magnitude and only 7.2 arcseconds away.
