Kepler-425 b: A Jupiter-Like Planet in a Distant Star System
Kepler-425 is a K1 V star located 2110 light-years away. This star is classified as a main-sequence dwarf, and its spectral type places it in the K temperature class, cooler than the Sun. The star has an age of 5 billion years, a mass of 0.93 solar masses, a radius of 0.86 solar radii, and a temperature of 5170 K. Its reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's.
One planet orbits this star. Kepler-425 b is a Jupiter-like planet discovered by the transit method in 2014. Its radius of 11 Earth radii is larger than Earth's, placing it well above the threshold for its size class. The planet has a mass of 79.5 Earth masses, also larger than Earth's. Its mean density is 0.332 g/cm³, which is 0.0603 times Earth's.
Kepler-425 b completes one orbit in 3.8 days. This short period is typical of close-in planets detected through the repeated brightness dips of the transit method.
