SWEEPS-04 is an extrasolar planet orbiting the star SWEEPS J175853.92−291120.6 in the constellation Sagittarius approximately 27,710 light years away from the Solar System, making it the most distant exoplanet known. This planet was found in 2006 by the Sagittarius Window Eclipsing Extrasolar Planet Search program that uses the transit method.
The upper limit on the planet's mass is 3.8 times the mass of Jupiter. The best fit radius is 0.81 times that of Jupiter, but the uncertainty in this value is large, around 12%. It orbits at an average distance of 8,200,000 km from the parent star, taking 4.2 days to revolve around it.
