WASP-70 A and Its Jupiter-like Planet

WASP-70 A is a G4 star 725 light-years away, with a mass of 1.11 solar masses, a radius of 1.22 solar radii, a temperature of 5760 K, and an age of 9.5 billion years. Its reported mass estimate is larger than the Sun's, and its reported radius estimate is larger than the Sun's. One planet is known to orbit this host.

That planet, WASP-70 A b, is a Jupiter-like world discovered by transit in 2014. It has an orbital period of 3.71 days, a mass of 188 Earth masses, and a radius of 13 Earth radii. Its reported radius estimate is larger than Earth's, and its reported mass estimate is larger than Earth's. Its mean density is 0.465 g/cm³, 0.0844 times Earth's.
