Our solar system has four giant gas planets with rings: Saturn, Jupiter, Uranus and Neptune. Saturn is known for having the largest ring system, but do you know when the sixth planet from the sun got the magnificent network of rings? A team of astronomers claims it has found the answer.

Saturn didn’t have the ring system until sometime after the age of dinosaurs started on our planet, claimed the astronomer group. It means the gas giant’s rings are younger than dinosaurs. The astronomers conducted a study and found that not only Saturn’s rings, but its moons are also young.

Natural satellites around the planet may have formed approximately 100 million years in the past, the team estimated. It indicated that Saturn got its moons about 130 million years after dinosaurs started ruling earth.

Astronomers have been trying to find the exact age of Saturnian rings and its natural satellites since a long time. Before the new study, science community had a hunch that the planet’s moons were formed around 4.5 billion years ago when rest of the solar system was formed.

A study in 2012 by French astronomers revealed that the gas giant’s natural satellites are moving outward while orbiting it. “Moons are always changing their orbits. That's inevitable. But that fact allows us to use computer simulations to tease out the history of Saturn's inner moons. We find that they were most likely born during the most recent 2% of the planet's history”, said Matija Cuk from the SETI Institute in a statement.

Saturn has more than sixty known moons. According to astronomers, these natural satellites are influenced by the host and each other’s gravity. Tethys, Dione and Rhea are very young Saturnian moons, they said.
