WASP-170 b: A Jupiter-Like World
WASP-170 is a star 997 light-years from Earth with 0.93 solar masses, 0.938 solar radii, and a temperature of 5600 K. 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-170 b, a Jupiter-like world discovered by transit in 2018. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. WASP-170 b completes an orbit every 2.34 days. Its radius is 12.3 Earth radii, larger than Earth's, and its mass is 509 Earth masses, also larger than Earth's and roughly 1.6 times Jupiter's mass. Its mean density is 1.51 g/cm³, 0.274 times Earth's.
