Kepler-423 and Its Jupiter-Like Planet
Kepler-423 is a G-type main-sequence dwarf star located 2470 light-years away. It is classified as spectral type G4 V. The star has an age of 11 billion years, a mass of 0.85 solar masses, a radius of 0.95 solar radii, and a temperature of 5560 K. Its reported mass estimate is smaller than the Sun's, and its reported radius estimate is smaller than the Sun's. Its reported temperature is cooler than the Sun's. One planet is known to orbit this star.
Kepler-423 b is a Jupiter-like planet discovered by the transit method in 2014. It has a mass of 189 Earth masses, a radius of 13.4 Earth radii, and an orbital period of 2.68 days. Its reported radius estimate is larger than Earth's, and its reported mass estimate is larger than Earth's. Its mean density is 0.437 g/cm³, 0.0793 times Earth's.
