WASP-3 b: A Jupiter-Like World
WASP-3 is a star located 754 light-years away, and it hosts one planet. The star is estimated to be 2.1 billion years old, with a mass of 1.26 solar masses and a radius of 1.38 solar radii. Its temperature is 6400 K, and its reported mass, radius, and temperature estimates are all larger or hotter than the Sun's.
The planet, WASP-3 b, is a Jupiter-like world discovered by transit in 2007. This classification reflects its radius of 15.9 Earth radii, which exceeds four times Earth's radius. Its mass is 772 Earth masses, roughly 2.43 times Jupiter's mass, and it orbits its star every 1.85 days. Its mean density is 1.06 g/cm³, which is 0.192 times Earth's. Both its mass and radius estimates are larger than Earth's.
