Due to the host star's dimness, it was the second least irradiated hot Jupiter discovered by WASP at the time of discovery, with an equilibrium temperature of 763±16 K (490 °C; 914 °F); only WASP-59b was colder at 670±35 K (397 °C; 746 °F).

[8] From TESS observations conducted in 2019, a new transit signal was found to occur every 1.01153 days (24.277 h), which was confirmed to be caused by a planet with a radius 1.85 times that of Earth in 2022.

Archived radial velocity data from CORALIE and subsequent observations with HARPS indicate that the mass of the planet is approximately 6.26+1.84−1.83 M🜨, corresponding to a bulk density of 5.47+1.96−1.71 g⋅cm−3, consistent with an Earth-like composition.

This is deemed unlikely to have happened to WASP-132b, since the migration would leave other nearby planets scattered or even ejected from the system as the eccentric Jupiter sweeps the vicinity of its orbit clean with its gravitational influence.

Should it exist, it would have a minimum mass of roughly 18.5 MJ, likely making it a brown dwarf or low-mass star, and orbit WASP-132 with a period of >18 years.
