K2-97 and Its Jupiter-Like Planet
K2-97 is a star 2870 light-years away with one known planet. The star is 7.5 billion years old, has 1.17 solar masses, a radius of 4.14 solar radii, and a temperature of 4670 K. Its reported mass and radius estimates are larger than the Sun's, while its reported temperature is cooler than the Sun's.
The planet K2-97 b is Jupiter-like, discovered by transit in 2016. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. K2-97 b has a mass of 174 Earth masses, a radius of 13.5 Earth radii, and an orbital period of 8.41 days. Its reported radius and mass estimates are larger than Earth's. Its mean density is 0.395 g/cm³, 0.0717 times Earth's.
