HATS-51 and Its Jupiter-Like Planet
HATS-51 is a star 1270 light-years away with one known planet. The host star is 4.74 billion years old, has a mass of 1.19 solar masses, and a radius of 1.44 solar radii, with a temperature of 5760 K. Its reported mass and radius estimates are both larger than the Sun's.
The planet HATS-51 b is a Jupiter-like world discovered in 2017 by the transit method, in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness. Repeated dips help establish orbital periods. HATS-51 b orbits every 3.35 days. Its mass is 244 Earth masses and its radius is 15.8 Earth radii; both the radius and mass estimates are larger than Earth's. The planet's mean density is 0.341 g/cm³, 0.0618 times Earth's.
