SWEEPS-04 is an extrasolar planet orbiting the star SWEEPS J175853.92−291120.6 in the constellation Sagittarius approximately 22000 light years away (based on a distance modulus of 14.1) from the Solar System. This planet was found in 2006 by the Sagittarius Window Eclipsing Extrasolar Planet Search (SWEEPS) program that uses 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 (0.055 AU) from the parent star, taking 4.2 days to revolve around it. fILE:HST SWEEPS-4 2006.jpg|HST SWEEPS-4 2006.jpg File:Radial Velocities of SWEEPS-04 (UVES-VLT).jpg|Radial Velocities of SWEEPS-04 (UVES-VLT).jpg File:Artist's impression of a transiting Jupiter-mass exoplanet SWEEPS J175853.92-291120.6 b.jpg|Artist's impression of a transiting Jupiter-mass exoplanet SWEEPS J175853.92-291120.6 b.jpg ==See also== * Sagittarius Window Eclipsing Extrasolar Planet Search or ''SWEEPS'' * SWEEPS-10 * SWEEPS-11 * List of extrasolar planets 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「SWEEPS-04」の詳細全文を読む スポンサード リンク
