WASP-105 b: A Jupiter-Like Planet in a Close Orbit

WASP-105 is a star of spectral type K2 located 552 light-years from Earth. Its mass is 0.89 solar masses, its radius is 0.9 solar radii, and its temperature is 5070 K. The star's 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. One planet orbits this host.

That planet is WASP-105 b, a Jupiter-like world discovered by the transit method in 2017. With a radius of 10.8 Earth radii, it is larger than Earth, and its size classification reflects that radius rather than its composition. Its orbital period is 7.87 days. Its mass is 572 Earth masses, larger than Earth's and roughly 1.8 times Jupiter's mass. Its mean density is 2.53 g/cm³, 0.459 times Earth's.
