It is an F7 class dwarf star, with an internal structure just on the verge of the Kraft break.
[4] The primary seems to have UV-opaque matter in the line-of-sight, which may originate from atmosphere escaping from WASP-72b or from an unknown object in the interstellar medium.
[7] A faint stellar companion WASP-72B was discovered in 2020 at a projected separation of 281 AU.
[8] The planetary orbit is well aligned to the equatorial plane of the star, with misalignment equal to −7°+11°−12°.
[5] Despite the close proximity of the planet to the parent star, orbital decay was not detected as of 2020.
