What I am going to do:

Edit paragraphs-- fixing grammar, rewriting things in each paragraph, and adding more information. Giving the four main moons each a paragraph, and the other moons a paragraph.

Going to put information in a more organized order and way. Possibly more of an outline form.

Add pictures, possible animations, and a chart that will compare the Jovian moons.

For most planets, there's 1 interesting moon. Jupiter has 4. You have to cover all of them, but your life-form only has to live on one of them (if you decide that that's how it works). Wherever they live, they would likely know about the others, and their presence would affect their mythology. Be sure to look up and understand the significance of "synchronized orbits". It would be VERY important to your lifeforms.

The Four Jovian Moons Plus More..

Jovian is an adjective used to describe relations of the planet Jupiter( It is rooted from the word Jove. In Roman mythology Jove was was the supreme God. Jupiter is the biggest planet in the solar system, which is probably where the word Jovian comes into perspective. Jupiter has four main moons: Lo, Europa, Ganymede, and Callisto. They are referred to as Galilean satellites, and orbits around Jupiter, which orbits the Sun (

These four moons are all visible to the untrained eye when equipped with a telescope without the proper magnification. This was apparent to the man who discovered, Galileo Galilei. He was an Italian physicist, astronomer, mathematician, and philosopher. Galilei discovered the four moons in 1610. However, when viewed with the proper magnification, the number four becomes 63. Now there are 63 recorded moons and satellites in orbit around the Jovian planet.

Jovian Moons



The first of four moons that orbits around Jupiter is Io. The Io moon has the diameter of 3,642 kilometers (2,263 miles), and its mass is 8.94x10+22 kg. It also has more than 400 active volcanoes, and more than 100 mountains. It is the most volcanic body known to man. Its mountains are much higher than what is seen on Earth. They are about 52,000 feet tall.



Another one of Jupiter's main moons is Europa. The Europa moon is smaller than Earth's moon. It is mostly made up of silicate and its surface is composed of ice, which makes the moon the smoothest in our solar system.



The next Jovian moon is Ganymede. The Ganymede moon is the largest moon in our solar system. It is composed of a rocky core with a water/ice mantle and crust of rock and ice. This moon has no atmosphere.



The last Jovian moon is Callisto, which is the third largest moon in our solar system. The crust of Callisto is about four billion years old. Its diameter is 600 kilometers and its ring extends to 3,000 kilometers. Underneath the crust of Callisto is an ocean that is salty and is six miles thick.

Other Jovian Moons and Satellites

The 63 Jovian moons and satellites are grouped. There are the Regular Satellites and the Irregular Satellites. The Regular Satellites are spilt into groups as well; the Interior Satellites or the Amalthea Group, and the Main Group or the Galilean moons. The Main Group or Galilean moons are the four most massive moons in the Jovian System. The Galilean moons consist of Io, Europa, Ganymede, and Callisto. They are also some of the biggest bodies in the entire Solar System not to mention the Jovian System. The Interior satellites orbit very close Jupiter. This group consists of four satellites: Metis, Adrastea, Amalthea, and Thebe. The Irregular Satellites are small masses that orbits around Jupiter. The Irregular satellites are broken up into group. This group consists of four groups as well; the Himalia Group, Carme Group, Ananke Group, the Pasiphae Group and the Carme Group.
