Planetary companion

WASP - 1b was identified as a candidate exoplanets within the SuperWASP surveys and later confirmed using the radial velocity method. It has a mass of about 89 percent of the mass of Jupiter. As the planet orbits its star very close - the distance is 0.0382 (± 0.0013 ) astronomical units, or about four percent of the distance from the earth to the sun - he needs for a circling only 2.51997 (± 0.00016 ) days.
