WASP-53 and Its Two Planets
WASP-53 is a star 657 light-years away with two known planets. The star has a reported mass of 0.839 solar masses, a reported radius of 0.798 solar radii, and a temperature of 4950 K. Its reported mass estimate is smaller than the Sun's, its reported radius estimate is smaller than the Sun's, and its reported temperature is cooler than the Sun's.
WASP-53 b is a Jupiter-like planet discovered by transit in 2017. Its mass is 678 Earth masses, its radius is 12 Earth radii, and its orbital period is 3.31 days. Its reported radius estimate is larger than Earth's, and its reported mass estimate is larger than Earth's. Its reported mass estimate is roughly 2.13 times Jupiter's mass, and its mean density is 2.14 g/cm³, 0.388 times Earth's.
WASP-53 c was discovered by radial velocity in 2017. Its minimum mass has a reported lower limit of 5196.5205 Earth masses, and its orbital period has a reported lower limit of 2840 days. A minimum mass is a lower bound on a planet's true mass.
