SWEEPS-11 is an extrasolar planet orbiting the star SWEEPS J175902.67−291153.5 in the constellation Sagittarius, approximately 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.{{Cite web |title=HEC: Top 10 Exoplanets |url=http://phl.upr.edu/projects/habitable-exoplanets-catalog/top10 |url-status=dead |archive-url=https://web.archive.org/web/20131217224149/http://phl.upr.edu/projects/habitable-exoplanets-catalog/top10 |archive-date=17 December 2013 |access-date=16 July 2018 |website=Planetary Habitability Laboratory @ UPR Arecibo}} 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 radius of 1.13 times that of Jupiter, but the uncertainty in this value is large, around 21%. 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 orbit the star. It is also the most distant planet yet discovered.
