HATS-38 and Its Jupiter-Like Planet
HATS-38 is a star 1120 light-years away with one known planet. The host star is 11.9 billion years old and has a mass of 0.89 solar masses, a radius of 1.11 solar radii, and a temperature of 5730 K. Its reported mass estimate is smaller than the Sun's, while its radius estimate is larger than the Sun's and its temperature is cooler.
The system's only cataloged planet is HATS-38 b, a Jupiter-like world discovered by transit in 2020. It completes an orbit in 4.38 days. Its radius of 6.88 Earth radii exceeds Earth's, and its mass of 23.5 Earth masses is also larger than Earth's. The planet's mean density is 0.398 g/cm³, 0.0721 times Earth's.
