Less than one-third the mass of Jupiter, Saturn is still an enormous planet. Saturn has a mass of about 95 Earths and has a very rapid rotation rate. Because its rotation rate is so rapid, it has an obvious oblateness. This oblateness is caused by a outward push at the middle, from the spin rate, causing a large bulge at the planet's equator and a flattening at the planet's pole regions.

The most obvious feature of Saturn, is its planetary ring system. Saturn has 7 main ring sections labeled A thru G. These ring sections consist of over 3,000 individual rings of various sizes, shapes, and compositions. Between some of the ring sections appears to be a "gap", but actually contains some ring material within it. This "gap", is known as Cassini Division, and lies between ring sections A and B. A smaller gap, known as Encke Division, is found in the outer part of ring section A. Of the three main ring sections, B is the brightest, followed by A, and then by the almost translucent C section.

In Roman mythology, Saturn is the god of agriculture. It is said that his name is connected with the word satus, which means "sowing or planting." The myths about Saturn depict him as presiding over a golden age of happiness and plenty. The ancient Romans considered him a god of fertility and planting. He had a mythical reign for a time, a utopian era known as the Golden Age. Peace, happiness and innocence abounded. Saturn taught humans the arts of agriculture and was dedicated to welcoming the germinating impulse of Nature.

Saturn's wife is the goddess Ops, which means "bounty," for life is nourished by her bounty, or it comes from opus, which means "toil," which is needed to bring forth the fruits of trees and fields. Thus when we pray to Ops we make sure to touch the Earth, for she is the mother of everything mortal.

The Greeks called Saturn "Kronos,"which is almost the same as their word for time (Khronos), therefore it is said that he is the god of Time. Saturn was the son of Heaven and Earth, Uranus and Gaea and became King of the gods when his mother gave him the sickle to castrate his father when the work of generating the elements and other eternal things had been completed. When the deed was done, Saturn allowed the gonads of Heaven to drop to earth, which shows that the seeds of all things come from Heaven. So with the reign of Saturn, Father Time, the cosmic order and history as we know it began, for before him was Chaos, but with him came the measurement of time, the seasons and the years.
