<p>SWEEPS-04 is an <a href="/facts/Extrasolar_planet/zjfmqfUf">extrasolar planet</a> orbiting the <a href="/facts/Star/PFbd6ICx">star</a> <a href="/facts/SWEEPS_J175853.92%25E2%2588%2592291120.6/5n0ra868">SWEEPS J175853.92−291120.6</a> in the <a href="/facts/Constellation/nBQqgW8A">constellation</a> <a href="/facts/Sagittarius_(constellation)/ljtU4DQ2">Sagittarius</a> approximately 27,710 <a href="/facts/Light_year/IGc5NdQb">light years</a> away (based on a <a href="/facts/Distance_modulus/5Wt7RR4s">distance modulus</a> of 14.1) from the <a href="/facts/Solar_System/QIcLSazQ">Solar System</a>, making it (along with <a href="/facts/SWEEPS-11/6lGbeyEX">SWEEPS-11</a>) the most distant exoplanet(s) known. This planet was found in 2006 by the <a href="/facts/Sagittarius_Window_Eclipsing_Extrasolar_Planet_Search/6I22NtU4">Sagittarius Window Eclipsing Extrasolar Planet Search</a> (SWEEPS) program that uses the <a href="/facts/Methods_of_detecting_extrasolar_planets/vFIblQe9">transit method</a>.
</p><p>The upper limit on the planet's mass is 3.8 times the mass of <a href="/facts/Jupiter/95m7XjMT">Jupiter</a>. 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 (0.055 AU) from the parent star, taking 4.2 days to revolve around it.
