Kepler-40 and Its Jupiter-Like Planet
Kepler-40 is a single star 7520 light-years away with one known planet. The host is an F5 IV star with 1.48 solar masses and 2.13 solar radii, making its reported mass and radius estimates larger than the Sun's. Its temperature is 6510 K, hotter than the Sun's, and its age is 2.8 billion years.
The system's only planet is Kepler-40 b, a Jupiter-like world discovered by transit in 2010. It has a radius of 13.1 Earth radii and a mass of 699 Earth masses, both larger than Earth's corresponding values. That mass is roughly 2.2 times Jupiter's mass. Its mean density is 1.71 g/cm³, 0.31 times Earth's. Kepler-40 b completes an orbit in 6.87 days.
