The planet WASP-50b is 1.14 times the radius of Jupiter, the largest planet in our Solar System. It is thus much bigger than Earth.
WASP-50b is about 1 and a half times the mass of Jupiter, which means that WASP-50b is about the same density as Jupiter.
WASP-50b orbits at a distance of 4.36 million km, taking 1.96 days to go round its orbit.
The brightest stars in the plot have magnitude −1 and the faintest have magnitude 6, so, with a visual magnitude of 11.6, WASP-50 is much fainter than these stars. You would need a telescope to see it.
