When was aquila discovered




















Other stars of interest in Aquila includes the yellow-white stars Alshain Beta Aquilae and Bezek Eta Aquilae ; the blue-white stars Al Thalimain Iota Aquilae and Tseen Foo Theta Aquilae ; and the pulsating variable star R Aquilae, which is a red-hued giant star found light-years away whose apparent magnitude varies from 6 to 12 over a period of 9 months.

There are no Messier objects in Aquila, but it does contain several notable deep-sky objects, including nebulae , star clusters , and the biggest galactic superstructure in the whole universe. It can be seen clearly with even a small telescope, and sits 5 degrees to the southwest of Zeta Aquilae, where its stars form a sort of loose diamond shape. This cluster is found 4.

The two meteor showers associated with the constellation of Aquila are called the June Aquilids and the Epsilon Aquilids, although both were detected using radar, and none have ever been photographed. With a visual magnitude of 0. Altair is a blue subdwarf star located only It is one of the closest stars visible to the naked eye. Tarazed is the second brightest star in Aquila with a magnitude of 2. It is an orange giant star that lies light years distant.

With a magnitude of 2. It is a triple star system located approximately 83 light years from our solar system. Aquila contains no Messier objects, but does contain a number of interesting deep-sky objects. It is located 7, light years from Earth. It has three stars brighter than magnitude 3. The brightest star in the constellation is Altair, Alpha Aquilae spectral class A7 V , which is also the 12th brightest star in the sky. Altair is also the nearest star in Aquila, at a distance of only Aquila has nine stars with known planets.

HD G2IV has two planets, discovered in and Xi Aquilae, a red clump giant G9 III also known by the name Libertas, has a confirmed exoplanet, named Fortitudo, that was discovered in Aquila contains eight named stars. Aquila does not contain any Messier objects. There are two meteor showers associated with the constellation: the June Aquilids and the Epsilon Aquilids.

Ganymede is represented by the neighbouring constellation Aquarius. In another story, the eagle is found guarding the arrow of Eros represented by the constellation Sagitta , which hit Zeus and made him love-struck.

In the story, Zeus later placed the images of the eagle and the swan among the stars to commemorate the event. Altair is the 12th brightest star in the sky, with an apparent magnitude of 0.

It is an A-type main sequence star hydrogen fusing dwarf that has three visual companions. Lying only Altair has 1. The star also moves across the sky relatively quickly. It shifts by about a degree in years. The star Altair. Altair is one of the three stars that form the Summer Triangle , an asterism that can be seen directly overhead at mid-northern latitudes in the summer.

Altair is the southern star in the triangle. Alshain is only the seventh brightest star in Aquila, but was designated Beta Aquilae nonetheless by Johann Bayer. It is a class G subgiant approximately Alshain is six times more luminous than the Sun and slightly variable in luminosity.

It has an apparent magnitude of 3. Tarazed is the second brightest star in Aquila. Tarazed is times more luminous than the Sun and has a radius of solar, taking up about half an AU in the sky. It is a known source of X-rays. Tarazed is about million years old and yet it is already burning helium into carbon in its core. Epsilon Aquilae, or Deneb el Okab, is a triple star system about light years distant.

Epsilon Aquilae has an apparent magnitude of 4. The companions, suspected optical binaries, are 10th magnitude stars.
