The mass seemed a bit ridiculous to me (there's no metal I know that could account for such a mass of an Earth-sized planet) so read the actual paper to get the details. The mass mentioned is simply an upper limit to what they can measure and used that to determine it's a planetary-mass object and not something more exotic. The actual mass is likely to be very much lower, probably close to Earth's. However, they did determine that it has an iron core much more massive than the Earth's, so is likely a little more massive and dense.
As for the orbit, that's much easier to determine and is pretty accurate, so yes, assuming it has an axial tilt, you'll get all four seasons in just over four hours! As it orbits about 500 thousand miles from the star though, they'll all be very hot seasons...
[Earth orbits about 90 million miles from the sun].
