The spacecraft “Cassini” burned up in the atmosphere of Saturn two years ago, but the results of his observations are still helping scientists to make amazing discoveries. The five satellites of Saturn under the names of pan, Daphnis, Atlas, Pandora and Pimeta move very close to the rings of the planet and have very strange forms. For example, the Atlas resembles a flying saucer aliens, and the pan looks like a huge flying dumpling. Researchers at NASA have studied collected by the apparatus Cassini data, and finally understand why the satellites gained such bizarre forms.
The satellites move very close to the rings of the planet, so it is logical to assume that they somehow interact with them. According to researchers from NASA, they have a porous surface and a solid core, and bizarre shapes are created due to the fact that they are attracted and stick the particles of the rings.
We found that these satellites are harvested from the rings of ice particles and dust, forming a small skirt around the equator. More dense body would be more spherical, because the gravity attracted material.

Spectral map of a surface closest to Saturn satellites pan and Daphnis have shown that they have a reddish color. What minerals give them this shade is still unknown, but scientists suspect that they are a mixture of organic compounds and iron. More remote areas of the planet’s satellites under the title of Atlas, Prometheus and Pandora are blue — hue were attached to the ice particles and water vapor.
The above-mentioned satellites of Saturn, apparently, still attract the particles of the rings and increase in size. Besides these there are many other satellites are smaller, what caused their formation, researchers are unknown even to this day. There is speculation that they formed during the destruction of a certain large object after the collision with the asteroid.
