Gamma Aquilae (γ Aql, γ Aquilae) is a star in the constellation Aquila. It has the traditional name Tarazed.[11] This star has an apparent visual magnitude of 2.712,[2] so it is readily visible to the naked eye at night. Parallax measurements place it at a distance of 395 light-years (121 parsecs) from Earth.[1]

Gamma Aquilae is a relatively young star with an age of about 100 million years. Nevertheless, it has reached a stage of its evolution where it has consumed the hydrogen at its core and expanded into what is termed a bright giant star, with a stellar classification of K3 II.[3] The star is now burning helium into carbon in its core. After it has finished generating energy through nuclear fusion, Gamma Aquilae will become a white dwarf.[11]

The interferometry-measured angular diameter of Gamma Aquilae is 7.271 ± 0.073 mas,[12] which, at its estimated distance, equates to a physical radius of about 95 times the radius of the Sun.[7] With almost six times the Sun's mass, this is an enormous star that is radiating over 2,500 times the luminosity of the Sun.[6] An effective temperature of 4,210 K in its outer envelope gives it the orange hue typical of K-type stars.[8][13]
