Saturn's ring is much younger than the planet

Saturn's ring is younger than scientists have predicted so far and has reached the last 10-100 million. , said a study published on Thursday, based on data collected by NASA's Cassini probe.

The sixth planet was formed from central light around 4.5 billion BC. For years, like other members of the Solar System, most of their lives have no impressive bright and wide rings at this time.

Astronomers have long assumed that the ring was a rather new creation that might appear before Saturn's satellites or the collapse of a comet near the planet.

Some of these problems are focused on the Cassini mission. US and European cyberspace investigations were released in 1997 and, after completing the research program, were directed to Saturn's atmosphere.

At the end of his mission, Cassini rotates twenty-four times around Saturn, runs between the planet and his ring. This probe is closer to Saturn than other spacecraft.

After investigating how the Cassini flight trajectory was affected by ring gravity, scientists were able to calculate the mass and approximate age of this derivative.

"Only when we are so close to Saturn's last revolution in Cassini can we make measurements to make new discoveries," said Luciano Iess, the studio's lead author, working at Sapienza University in Rome.

To find out the age of the ring and the masses is "one of the main objectives of its mission," the investigator said.

Scientists assume that the mass is lower, younger is the ring, because in the long run they have to attract more cosmic debris and get worse.

99 percent Ring mass consists of ice.

The study authors did not discuss the question of the origin of rings, but stated a theory that supports the formation of these derivatives due to comet or satellite collisions.
