The planet WASP-60b is 0.9 times the radius of Jupiter, the largest planet in our Solar System. That makes its radius about 9 times larger than Earth’s radius.

WASP-60b is roughly half the mass of Jupiter so it is therefore less dense.

The star WASP-60 is 1.14 times the radius of the Sun. Its spectral type is G1 which makes it a yellow dwarf similar to our Sun. It has a brightness of visual magnitude 12.2.

The planet, WASP-60b, orbits at a distance of 8.25 million km from its star, taking 4.3 days to go round its orbit.

WASP-60 lies in the constellation of Pegasus. Its coordinates are right ascension 23:46:40.0 and declination +31:09:21. The system is a distance of 400 parsecs away from us.

The brightest stars in the plot have magnitude 1 and the faintest have magnitude 6, so, with a visual magnitude 12.2, WASP-60 is much fainter than these stars. You would need a telescope to see it.

WASP-60b is in a retrograde orbit! That means that the host star spins one way, but the planet orbits the other way. This is not seen in our Solar System, where all the planets orbit in the same direction that our Sun spins.

WASP-60 was announced in 2013 in a paper led by Guillaume Hébrard of the Institut d’astrophysique de Paris.
