About Solar System
The Solar System is the gravitationally bound planetary system of the Sun and the objects that orbit it, either directly or indirectly. Of the objects that orbit the Sun directly, the largest are the eight planets, with the remainder being smaller objects, such as the five dwarf planets and small Solar System bodies.

Saturn overtakes Jupiter as the planet with the most moons
Roll over Jupiter, Saturn, the new Moon King
is Saturn, Jupiter, The Planet with The Most moons has become obsolete, according to U.S. researchers.
the A-team discovered a haul of 20 new moons in Orbit around the ringed planet, and thus his total, 82; Jupiter, by contrast, 79 natural satellite.
The Moons were discovered with the Subaru telescope on Maunakea, Hawaii.
the newly discovered objects in the orbit of Saturn, about 5 km (three miles) in diameter; 17 of them are orbiting The Planet "backwards".
This is known as a retrograde direction. The Other three moons orbiting in the prograde direction - the same direction as Saturn rotates.
Two of the prograde moons will take about two years to travel Once Around the ring planet.
The more distant retrograde moons, and is one of the prograde moons, each of More Than three years to complete the orbit.
"the study of orbits of these moons can reveal their origin, as well as information about the conditions that surround the Saturn, at the time of its formation," said Dr. Scott Sheppard of the Carnegie Institution for Science in Washington DC, who led The Team .
Dr. Sheppard told Bbc News that Jupiter was The Planet with The Most known moons since the late 1990s.
to be The outer moons in the new haul to seem to be grouped in three different clusters, based on the inclinations of the angles, you are orbiting The Planet .
scientists believe that the retrograde and prograde moons are The Broken remains of at least three of the larger facilities. These larger objects are destroyed by the collisions, either between the different moons, or with external objects such as asteroids were passing.
One of the newly discovered retrograde objects is The Most well-known of Saturn's satellites.
"These moons are quite oblique trajectories to Saturn, and are pretty Far Out , so that we think that they formed with The Planet , we think they were captured by The Planet in The Past . If an asteroid happened to pass by, you can't collect it today because you can't disperse your energy," Dr. Sheppard said to Bbc News .
But, in the Solar System 's youth, when Saturn was in The Process of education, a cloud, or "disc" of gas and dust that surrounded The Planet . This helped to dissipate the energy of delivery of objects. But in most cases, these bodies spiral ended in the earth and become part of it.
The observations led to The Discovery were thinking with the Subaru telescope"that these moons, along with the gas and dust. These were comets or asteroids, which explains in passing," Dr. Sheppard.
"Most of the objects would spiral in to the earth and help The Planet itself. But we think that these objects were captured right when the gas and the dust began to dissipate. So you were trapped in orbits around The Planet rather than crashing into The Planet . We think these are The Last remnants of what formed [Saturn]. "
The discoveries have been made, through the application of new computing algorithms to data collected between 2004 and 2007, with the Subaru telescope. These algorithms were able to match orbits potential of moons to be identified and the old data.
"We thought you were The Moons of Saturn, but we were not able to get a full orbit in order to determine this," said Dr. Sheppard.
"with this new computer power, I was able to find 20 objects that we thought were The Moons officially the tracks for you. "
The original observation team, Dr. Sheppard, David Jewitt of the University of California, Los Angeles (UCLA), and Jan Kleyna of the University of Hawaii.
Dr. Sheppard said, more moons were probably waiting to be found around Saturn. But the astronomers needed larger telescopes, such as those that come online to discover in the coming Decades , these smaller satellites of around 1 km in size
has taken The Team , they are named after the giants of Norse, Gallic, or Inuit mythology, corresponding to the three different clusters.
