Did you know that Saturn, the sixth planet from the Sun, is named after an ancient Roman god? Here are more fun and fascinating facts about the planet Saturn!
Saturn’s Mythology
The ultimate origins of Saturn’s name and mythology are mysterious, as the character has been associated with a number of ancient cultures. In ancient Rome, Saturnus was considered the god of wealth and agriculture, and was the focus of an annual celebration called Saturnalia. Held on the 17th of December (in the Julian calendar), Saturnalia featured gift-giving and ample festivities.
Saturn was later associated with Cronus, a figure of Greek mythology. He became the ruler of the universe when he led a successful rebellion against his father, Uranus. It’s said that during the time of Cronus鈥 rule, man experienced a peaceful and bountiful Golden Age.
In both cases, it seems that Saturn was associated with prosperity and peace鈥攆eatures fit for the 鈥淟ord of the Rings!鈥
The Discovery of Saturn
The planet has been observed with the naked eye for millennia, but our fascination with Saturn truly blossomed in 1610, when Galileo pointed his crude telescope towards the most distant of the known planets. He knew that he was seeing something very different, but his meager 20x telescope didn’t give him a very sharp image.
Galileo never did realize that Saturn had full rings. His best drawings depicted a sphere with handles, something like a sugar bowl. Saturn’s form lies totally outside human experience. There simply is no earthly example of a globe surrounded by unattached rings.
Today, even the most inexpensive department-store telescope easily reveals Saturn’s glorious rings. The only image-spoiling interference is the frequent turbulence of Earth’s atmosphere. If you encounter 鈥減oor seeing,鈥 wait for a night when stars aren’t twinkling and planetary images are rock-steady.
Saturn’s Orbit
The ringed planet’s meandering is predictable and simple.
- Each year, as Earth revolves around the Sun, we spend a month or two close to Saturn鈥攁lways at a time when the three bodies form a straight line, with our world sandwiched in the middle, in a configuration called opposition.
- Then we move on, whirl around the Sun once more, and again approach Saturn.
- Saturn, however, is a very slow-moving planet. In its own 29-1/2 year orbit, Saturn inches forward ever so slightly, so that our rendezvous occurs about 2 weeks later each year.

- The unattached rings of Saturn are composed of billions of pieces of ice, dust, and rock ranging in size from as tiny as a grain of salt to as big as a house.
Saturn has been visited by several probes. In 2004, Cassini started on a four-year mission to explore the planet, its rings, and its Moons. The 13-year mission ended in September, 2017. .
