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.
[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.
It takes just over 4 days to complete an orbit around its star, making it a typical hot Jupiter.
[7] The planetary orbit is well aligned with the equatorial plane of the star, the misalignment angle being equal to −4±22°.
