SWEEPS-11 is an extrasolar planet orbiting the star SWEEPS J175902.67−291153.5 in the constellation Sagittarius approximately 22000 light years away from the Solar System (based on a distance modulus of 14.1). This planet was found in 2006 by the Sagittarius Window Eclipsing Extrasolar Planet Search (SWEEPS) program that uses transit method.
This hot Jupiter has a mass 9.7 times that of Jupiter and a radius of 1.13 times Jupiter. The planet orbits at about 1.75 times closer to the star than 51 Pegasi b is to 51 Pegasi, taking only 1.8 days or 43 hours to revolve around the star.
