Kepler-447 and Its Jupiter-Like Planet
Kepler-447 is a Sun-like G8 V star located 874 light-years away. It has 1 solar mass, 1.05 solar radii, and a temperature of 5490 K, which is cooler than the Sun's. One planet orbits this star.
That planet is Kepler-447 b, a Jupiter-like world discovered by transit in 2015. A transit occurs when a planet passes in front of its star from our viewpoint, dimming the observed brightness. This planet completes one orbit in 7.79 days. Its mass is 435 Earth masses, which is larger than Earth's, and its radius is 18.5 Earth radii, also larger than Earth's. Its mean density is 0.38 g/cm³, or 0.0689 times Earth's. Jupiter-like planets exceed four times Earth's radius, placing Kepler-447 b well within that class.
