 EPOD - a service of USRA

The Earth Science Picture of the Day (EPOD) highlights the diverse processes
and phenomena which shape our planet and our lives. EPOD will collect and
archive photos, imagery, graphics, and artwork with short explanatory

   Summary Author:  John Chumack;  Jim Foster

    Altair, one of the brightest stars visible during summer (in the
   Northern Hemisphere), gets relatively little attention compared to
   stars such as  Vega and  Antares. Nonetheless, it has a stunning
   background star field. Also designated α Aquilae (Alpha Aquilae), it’s
   the brightest star in the constellation of  Aquila (The Eagle) and
   the twelfth brightest star in the night sky. Altair is relatively close
   by our solar system --16.7 light-years ( 5.13 parsecs) away. It’s
   approximately 1.8 times the mass of the Sun and 11 times as
    luminous.

   The southernmost star of the vertices that form the “ Summer
   Triangle” asterism, Altair is visible nearly all summer and well into
   autumn. Look for it now in the western sky, just after sunset. Photo
