TOI-5688 A b: A Jupiter-like World Around a Cool Star
TOI-5688 A is a star 738 light-years away, and it hosts one known planet. The star is estimated to be 7.2 billion years old, with a mass of 0.6 solar masses and a radius of 0.57 solar radii. Its temperature is 3710 K, cooler than the Sun.
The planet, TOI-5688 A b, is Jupiter-like. It was discovered by transit in 2024, when it passed in front of its star and caused a small dip in observed brightness. Its orbital period is 2.95 days. The planet has a mass of 124 Earth masses and a radius of 10.3 Earth radii, both larger than Earth's. Its mean density is 0.625 g/cm³, 0.113 times Earth's.
