WASP-172: A Planet Around an F-Type Star

WASP-172 is a star 1760 light-years away with one known planet. The star is a main-sequence F1 V dwarf, making it hotter and more massive than the Sun. Its mass is 1.49 solar masses, its radius is 1.91 solar radii, and its temperature is 6900 K, with an age of 1.79 billion years.

The single planet, WASP-172 b, is a Jupiter-like world discovered by the transit method in 2018. Its radius is 17.6 Earth radii, larger than Earth's, and its mass is 149 Earth masses, also larger than Earth's. Its orbital period is 5.48 days. Its mean density is 0.151 g/cm³, which is 0.0274 times Earth's.
