This is the second biggest in our solar system and the only planet whose average mass does not exceed that of water so if there is a sea that surround Saturn could soar.

At Saturn from a modern telescope in 1610, Galileo draw it as a globe bounded by two smaller ones as a head with large ears (the first one who came up with the Mickey Mouse logo). Galileo thought it was moons but when two years later reviewed the planet had disappeared. Later in 1655 the Dutch astronomer Christian Huygens discovered Saturn having had a satellite orbiting Titan, announced that the planet should be surrounded by an equatorial ring.

Enlarge the probability of an asteroid crash with Earth

Scientists at the Cardiff Centre of Astrobiology, UK, have developed a mathematical model that confirms that currently is experience our solar system called the extensive hydroplane, which increase the chances of an asteroid collide with Earth. An asteroid is a rocky body that orbits the Sun Becomes meteorite when it enters Earth's atmosphere. In astronomy, is called the huge hydroplane in the middle of the region in which they are most of the stars of a flattened galaxy, as twist galaxies.
