WASP-194: A Distant Star With a Single Known Planet
WASP-194 is a star 1560 light-years away, and one planet has been found orbiting it. The host star has a mass of 1.29 solar masses, a radius of 1.41 solar radii, and a temperature of 6410 K, all larger or hotter than the corresponding values for the Sun. Its age is 0.75 billion years.
The known planet is WASP-194 b, a Jupiter-like world discovered by the transit method in 2025, when it was seen passing in front of its star and dimming its light. It completes an orbit every 3.18 days. Its radius is 15.5 Earth radii, larger than Earth's, and its mass is 373 Earth masses, also larger than Earth's. Its mean density is 0.554 g/cm³, 0.101 times Earth's.
