Saturn's rings are younger than the planet itself



Saturn's rings were considered younger than scientists and appeared within the last 10 to 100 million years, according to studies published on Thursday based on findings of NASA's Cassini spacecraft.

The sixth planet from & # 39; the sun originated as 4.5 billion years ago, along with the rest of & # 39; the planets in our solar system, and today, most of them exist without the characteristic rings.

Astronomers had previously believed that the rings could be young, and perhaps arising from colossals between the months of Saturn or by a comet you & # 39; t enclose in & # 39; a planet tasteful.

Some of these responses have been sharply focused on Cassini, an unmanaged American problem, which started in 1997 and ended in 2017 with a plundered death in Saturn's surface.

At the end of his mission, Cassini made 22 jobs, which ran between Saturn and their rings, getting closer to them than any space in & # 39; e history.

By studying how Cassini's flight path was lured by the gravity of rings, scientists were the masses and the ranking age of & # 39; rings.

"Only because that was so close to Saturn in Cassini's end was we can collect the measurements to make the new discoveries," said lead lead Luciano Iess of Sapienza University of Rome.

Under the rings of age and mass is "a complete purpose of his mission," he said.

A lesser mass gives younger rings, because they as age will make the rings more fussy and wait more heavily.

The rings consist of 99% ice.

The study is not a question asked where the rings came, but supportive theories such as a comet or moon.
