U.S. scientists found that Phoebe does not belong to the Saturn system.

<P> American scientists in the May 5 issue of "Nature" magazine reported that from Cassini - Huygens Saturn probe data shows that the outermost of Saturn's satellite Phoebe is not part .Saturn system, but one of Saturn captured from the outer solar system objects. .According to the nebula theory, the solar nebula before the formation of a contraction the sun after the center to form atoms, the formation of planets around the nebula disk. .Similar hydrogen, lighter molecules of water that is pushed to the edge of the solar system, the formation of icy comets, asteroids or meteors. .United States, "Search for Extraterrestrial Intelligence," Research Institute scientists report that Cassini - Huygens probe on June 11 last year, data obtained show that the Saturn flyby, with Saturn's other satellites is different from Phoebe ice .content was low, with higher levels of rock, so the proportion of ice and rock is more like the remains of the solar nebula. .In addition, the surface of Phoebe and organic molecules and some minerals other than the orbit of Neptune, billions of kilometers from the Earth, "Cooper with" there are a number of similar objects. .In 1951, astronomers made beyond Neptune Cooper, hide a group of icy planets, zonal arrangement, after the scientific exploration has proven the existence of the asteroid belt. .Scientists say the evidence shows that a diameter of about 200 km from the solar system, Phoebe is actually the edge of the cold regions, rather than dry and hot formed in the inner solar system. .As the great planetary gravity, Cooper lead with some of the objects are the sun, scientists have discovered more than 700 so far similar objects, while Phoebe is in the process of flying to the sun captured by Saturn. .Previously, scientists also suspect that Phoebe is an outsider into the Saturn system, as it runs around the direction of Saturn's satellites and other earth the contrary, its orbit and the angle between the equator of Saturn is also very large. .This study confirms Phoebe is not a satellite of Saturn speculation. .Experts believe that the study of Phoebe, you can learn more about how the solar nebula formed the planets. .</ P>.
