Gamma Doradus, Latinized from γ Doradus, is the third-brightest star in the southern constellation of Dorado.[10] It is faintly visible to the naked eye with an apparent visual magnitude of approximately 4.25, and is a variable star, the prototype of the class of Gamma Doradus variables.[2] The star is located at a distance of 67 light years from the Sun based on parallax,[1] and is drifting further away with a radial velocity of +25 km/s.[5] Based on its motion through space, it appears to be a member of the IC 2391 supercluster.[11]

This is an F-type main-sequence star with a stellar classification of F1V.[3] It is a pulsating variable that varies in brightness by less than a tenth of a magnitude owing to nonradial gravity wave oscillations.[2] Four pulsation frequencies have been identified with periods of 17.6, 12.8, 16.3, and 18.2 hours.[8][12] The star is around 0.5–1.2 billion years old and is spinning with a projected rotational velocity of 57 km/s.[8] It has 1.6[6] times the mass of the Sun and 1.9[1] times the Sun's radius. The star is radiating seven[1] times the luminosity of the Sun from its photosphere at an effective temperature of 6,906 K.[1]

An infrared excess detected at multiple frequencies[13] indicates that the star is being orbited by a pair of debris disks.[14]
