Saturn is ahead of Jupiter’s number of satellites. Now in this planet are 82 of them, more than any other planet in the Solar system. Astronomers conducted a competition for the best name for the new satellites.
New moons of Saturn was discovered by a team of astronomers using ground-based Subaru telescope in the Observatory of Mauna Kea in Hawaii.
The diameter of the bodies found is about five kilometers away. 17 satellites are moving retrograde orbit. This means that they rotate in the opposite direction of the direction of rotation of the planet.
The remaining three satellites move in a straight orbit in the direction of rotation of the planet. Two of them encircle Saturn about two earth years. The period of rotation of the third – more than three years.
Retrograde satellites in average encircled Saturn for more than three years. At the same time, one of these satellites is recognized as the most remote from the planet Saturn.

After examining the orbits of these satellites, we will be able to understand more about their origin and the conditions in which an earth, – said astronomer Scott Shepard.
Now astronomers believe that some of the new satellites are the remnants of at least three major celestial bodies broken into pieces by collisions with other satellites or external objects, such as asteroids.
To identify satellites managed by applying the new algorithms with the Gemini South telescope. With the help of scientists were able to link the known orbit of the previously exposed potential moons of Saturn.

By the way, astronomers have announced a contest for the best name for the new satellites of Saturn. And anyone can take part in it. Maybe it will be you! There is only one requirement – the moons must be named after giants from Norse, Inuit, or Gallic mythology.
