HATS-74 A b: A Jupiter-like Planet in a Close Orbit

HATS-74 A is a star 976 light-years away. It is 11 billion years old, with a mass of 0.601 solar masses and a radius of 0.576 solar radii, making both its mass and radius smaller than the Sun's. Its temperature of 3780 K is cooler than the Sun's.

One planet orbits this host: HATS-74 A b. Discovered in 2021 by the transit method, when the planet passes in front of its star from our viewpoint and causes a small dip in observed brightness, it is classified as Jupiter-like, meaning its radius exceeds 4 times Earth's. Its radius is 11.6 Earth radii, larger than Earth's, and its mass is 464 Earth masses, larger than Earth's and roughly 1.46 times Jupiter's mass. It completes an orbit every 1.73 days. Its mean density is 1.65 g/cm³, 0.3 times Earth's.
