HAT-P-39 b: A Jupiter-Like World Around a Hotter, Larger Star

HAT-P-39 is a star 2270 light-years away, with a mass of 1.4 solar masses, a radius of 1.63 solar radii, and a temperature of 6430 K. Its reported radius estimate is larger than the Sun's, and its reported temperature is hotter than the Sun's.

One planet is known to orbit this host: HAT-P-39 b, a Jupiter-like planet discovered by transit in 2012. It completes an orbit every 3.54 days. Its radius is 17.6 Earth radii, larger than Earth's, and its mass is 190 Earth masses, also larger than Earth's. Its mean density is 0.192 g/cm³, 0.0349 times Earth's.
