KELT-12 and Its Jupiter-Like Planet
KELT-12 is a star 1200 light-years away with one known planet. The host star is estimated to be 2.2 billion years old, with a mass of 1.59 solar masses, a radius of 2.37 solar radii, and a temperature of 6280 K.
The star's reported mass and radius estimates are larger than the Sun's, and its reported temperature is hotter than the Sun's.
KELT-12 b is a Jupiter-like planet discovered by transit in 2017. It has an orbital period of 5.03 days, a mass of 302 Earth masses, and a radius of 20 Earth radii. Both its reported radius estimate and its reported mass estimate are larger than Earth's. Its mean density is 0.209 g/cm³, 0.038 times Earth's.
