One side supports that they are ancient, and were created simultaneously with Saturn from the original nebular material (around 4.6 billion years ago), [124] or shortly after the LHB (around 4.1 to 3.8 billion years ago). [125] [126] The other side supports that they are much younger, created around 100 million years ago.
Using this data, Mankovich was able to determine that a single day on Saturn lasts 10 hours, 33 minutes and 38 seconds. Decades ago, astronomers using magnetic field data from Voyager estimated a ...
in which J and S are the orbital periods of Jupiter (4332.59 days) and Saturn (10759.22 days), respectively. [2] This is about 52 days less than 20 years, but in practice, Earth's orbit size can cause great conjunctions to reoccur anytime between 18 years 10 months and 20 years 8 months after the previous one.

The sun passes south to north through the ring plane when Saturn's heliocentric longitude is 173.6 degrees (e.g. 11 August 2009), about the time Saturn crosses from Leo to Virgo. 15.7 years later Saturn's longitude reaches 353.6 degrees and the sun passes to the south side of the ring plane.
Earth may have had a ring made up of a broken asteroid over 400 million years ago, a study finds. The Saturn-like feature could explain a climate shift at the time.
