[3] The modern Sun symbol, a circle with a dot (☉), first appeared in Europe in the Renaissance. [3]

Altair in comparison with the Sun. Along with β Aquilae and γ Aquilae, Altair forms the well-known line of stars sometimes referred to as the Family of Aquila or Shaft of Aquila. [17]: 190 Altair is a type-A main-sequence star with about 1.8 times the mass of the Sun and 11 times its luminosity.
R Aquilae is a variable star in the equatorial constellation of Aquila. It is located approximately 760 light years distant from the Sun [ 6 ] and is drifting further away with a radial velocity of 35 km/s. [ 5 ]
Zeta Aquilae, or ζ Aquilae, is a binary star [8] system in the equatorial constellation of Aquila. It is readily visible with the naked eye, being of the third magnitude. [ 2 ] Based on parallax measurements obtained during the Hipparcos mission, it is approximately 83 light-years (25 parsecs ) distant from the Sun . [ 1 ]
