Kepler-426 and Its Jupiter-Like Planet
Kepler-426 is a G1 V star, a Sun-like main-sequence dwarf, located 2750 light-years away. Its reported mass estimate is 0.91 solar masses and its reported radius estimate is 0.92 solar radii, both smaller than the Sun's. The star is 5730 K and 6 billion years old. It hosts one known planet.
That planet is Kepler-426 b, a Jupiter-like world discovered in 2014 by the transit method. Its orbital period is 3.22 days. It has a mass of 108 Earth masses and a radius of 12.2 Earth radii. Its reported radius and mass estimates are both larger than Earth's. By density, at a mean density of 0.326 g/cm³, it is 0.0592 times Earth's.
