The planet WASP-64b is 1.3 times the radius of Jupiter, the largest planet in our Solar System. It it thus a gas-giant planet with a radius 13 times bigger than our rocky Earth.

WASP-64b is about 1 and a quarter the mass of Jupiter, which means that it has a similar density to Jupiter.

The star WASP-64 is very like our Sun, with a similar mass and radius.

WASP-64b orbits at a distance of 4 million km from its star, taking 1.6 days to go round its orbit.

WASP-64 lies in the constellation of Canis Major. Its coordinates are right ascension 06:44:27 and declination −32:51:30. The system is at a distance of 360 parsecs away from us.

The brightest star in the plot has a magnitude of −2 and the faintest have magnitude 6. With a magnitude of 12.3, WASP-64 is much fainter than these stars. You would need a telescope to see it.

Transits of WASP-64b across the face of its star were first seen by the WASP-South camera array, situated in South Africa. The discovery of the planet was announced in 2013 in a paper led by Michael Gillon.
