HATS-77 and Its Jupiter-Like Planet
HATS-77 is a star 1420 light-years away with one known planet. The star is 12.1 billion years old and has a mass of 0.655 solar masses and a radius of 0.643 solar radii, both smaller than the Sun's. Its temperature of 4070 K is cooler than the Sun's.
The planet HATS-77 b is Jupiter-like, discovered by transit in 2021. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. HATS-77 b has an orbital period of 3.09 days, a mass of 437 Earth masses, roughly 1.37 times Jupiter's mass, and a radius of 13.1 Earth radii, larger than Earth's. Its mean density is 1.08 g/cm³, 0.196 times Earth's.
