The WASP-181 Exoplanetary System
WASP-181 is a star with 1.04 times the mass of the Sun, and 0.96 times its radius. It is located 1444.87 light years away from the solar system and is estimated to be 2.5 billion years old, as compared to the Sun which is roughly 4.6 billion years old.
WASP-181 is known to have 1 exoplanets in orbit around it.
WASP-181 b was discovered by the SuperWASP observatory using the transit method. Its semi-major axis is 0.05 astronomical units, as compared to Earth's which is 1 astronomical unit. It takes 4.52 Earth days to complete an orbit around its host star, WASP-181.
The mass of WASP-181 b is 95.03 times the mass of Earth. The radius of WASP-181 b is 13.271 that of Earth. At more than 50 Earth masses, WASP-181 b is a gas giant, a planet whose mass is mostly made up of hydrogen and helium, like Jupiter and Saturn in our solar system.
