WASP-66, also known as TYC 7193-1804-1, is an F-type star in the constellation Antlia. It has an apparent magnitude of 11.6,[6] which is much too faint to be seen with the unaided eye and is located at a distance of 1,630 light years.[7]

WASP-66 has a classification of F4.5 V, which states that it is an ordinary F-type main sequence star that is fusing hydrogen at its core. At present it has 130% the mass of the Sun and 175 the radius of the Sun.[4] It has an effective temperature of 6,600 K,[4] which gives it a yellowish-white hue. The star is younger than Sun at 3.7+0.7
−1.2
billion years, and may be either metal-poor[4] or similar to Sun[5] in concentration of heavy elements. Currently it is spinning moderately with a projected rotational velocity of 13.4 km/s.[4]

According to a survey published in 2017, WASP-66 has one suspected companion - a red dwarf star with an effective temperature of 3,330±150 K and a projected separation of 6,800±700 AU.[8]
