Transcript of Saturn
Saturn was discovered thousands of years ago in prehistoric times and could be seen by the Ancient Greeks with a naked eye. It was first named “Kronos”, after the Greek god of agriculture. Rumor has it that this was due to its color, which assembled the color of wheat. Later, it became known as “Saturn”, who is the Roman form of Kronos.
Although the Romans and the Greeks knew about the planet’s existence itself, they had not known about its rings. In 1610, Galileo discovered them with his telescope, but they were not identified as planetary rings until Christian Huygens revealed this fact in 1655.
The Lord of the Rings
Over time, many astronomers including Christian Huygens
, Giovanni Domenico Cassini
, and William Herschel
discovered several moons orbiting Saturn.
Saturn’s atmosphere is thick. Mainly, it is composed of molecular hydrogen and helium. It also contains clouds and storms with winds reaching 400 miles per second.
Name of Probe/ Spacecraft
What Was Discovered
Voyager 1 (1977)
Each obvious ring is composed of several smaller rings.
Voyager 2 (1977)
Saturn has over 1,000 ringlets, it has a Great White Spot, and it has seven satellites.
Pioneer II (1979)
Spacecrafts would be able to easily pass through the asteroid belt.
•Saturn is less dense than water.
•Approximately 750 earths can fit inside Saturn.
•Summer on Saturn lasts about eight Earth years.
•The sizes of ice and rock in Saturn’s rings range from as tiny as a grain of sand to as large as huge buildings. Some even stretch to one kilometer across.
•At times, Saturn is the third brightest planet in the sky.

Whoa, those are some fat wigs they have there...at least William Herschel seems normal (except for the fact that he's just staring off into space...haha, get it? space? ahahahahahahahahaha not funny)
Hmm...look more like furry bubbles to me.
Sorry for the obnoxious colors. I just had to do it.
I tried my best. It's hard to make Saturn float in water.
