The planet WASP-63b is 1.43 times the radius of Jupiter, the largest planet in our Solar System. That makes it 14 times the radius of Earth. It is giant planet made of gas, whereas our Earth is a small, rocky planet.
Despite being larger, WASP-63b is only around half the mass of Jupiter, which means it is much less dense.
WASP-63b orbits at a distance of 8.59 million km, taking 4.38 days to go round its orbit.
WASP-63b has been observed with NASA’s Hubble Space Telescope. The observation found that the planet has a fairly cloudy atmosphere with some signs of water vapour.
The discovery of WASP-63b was announced in a paper led by Coel Hellier of Keele University, who leads the team that built WASP-South.
WASP-South is an array of cameras out in the Karoo desert of South Africa. It was the first to discover the transits of WASP-63b.
