SWEEPS-11

Common card · No. 499385

SWEEPS-11 is an extrasolar planet orbiting SWEEPS J175902.67−291153.5 in the constellation Sagittarius, around 27,710 light years away from the Solar System (based on a distance modulus of 14.1), making it (along with SWEEPS-04) the most distant exoplanet(s) known. This planet was found in 2006 by the Sagittarius Window Eclipsing Extrasolar Planet Search (SWEEPS) program that uses the transit method. This hot Jupiter has a mass 9.7 times that of Jupiter and a diameter of 1.13 times that of Jupiter, but the uncertainty in this value is large, around 21%. The planet orbits at around 1.75 times closer to the star than 51 Pegasi b is to 51 Pegasi, taking only 1.8 days or 43 hours to orbit the star. It is also the most distant planet yet discovered.
