HATS-66 and Its Jupiter-Like Planet

HATS-66 is a star 4820 light-years away with one known planet, HATS-66 b. The host star is 2.17 billion years old, has a mass of 1.41 solar masses, a radius of 1.84 solar radii, and a temperature of 6630 K. Its mass and radius are larger than the Sun's, and it is hotter than the Sun.

HATS-66 b was discovered in 2018 by the transit method, which detects the small dip in a star's brightness when a planet passes in front of it. The planet is Jupiter-like, meaning its radius exceeds 4 times Earth's. Its radius is 15.8 Earth radii, larger than Earth's. Its mass is 1690 Earth masses, larger than Earth's and roughly 5.33 times Jupiter's mass. It completes an orbit every 3.14 days. Its mean density is 2.36 g/cm³, 0.428 times Earth's.
