HATS-43 and Its Single Known Planet
HATS-43 is a star 1180 light-years away with one planet in its system. The star is 8.6 billion years old and has a mass of 0.837 solar masses, a radius of 0.812 solar radii, and a temperature of 5100 K. Its mass and radius are smaller than the Sun's, and it is cooler than the Sun.
The only planet known around HATS-43 is HATS-43 b, a Jupiter-like world discovered by the transit method in 2018. Its radius of 13.2 Earth radii places it above the Jupiter-like threshold of four Earth radii. It is more massive than Earth, at 83 Earth masses, and its mean density is 0.198 g/cm³, 0.0358 times Earth's. HATS-43 b completes an orbit in 4.39 days.
