While viewing Jupiter, he discovered four satellites orbiting around the planet Jupiter was the chief of the gods for the Romans, the way Zeus was for the Greeks Fifth Planet from the Sun; largest Planet in the Solar System The Italian scientist, Galileo was the first astronomer to view Jupiter through a telescope In May 2002, astronomers announced an additional 11 moons for Planet Jupiter

I’m originally 100 lbs on Earth, but now I’m 250! It takes Jupiter 9 hours, 55 minutes to orbit around it’s own axis. Rotation around Sun: 12 YEARS

Distance from Sun: 483 1/2 million miles Distance from Earth: 390,682,810 miles

Diameter: 142,800 km (Earth's diameter is 12,800 km) Mass: ×1027 kg (317.8 Earths) Surface area: 6.14×1010 km2 (120.5 times the surface area of Earth) The mass of Jupiter is 2.5 times larger than all of the planet’s masses combined.

On the cloud tops of Jupiter, the temperature is about -145 degrees C. At the center, it is 35,700 degrees C. At night, the cloud tops are below -150 degrees C. Since Jupiter is a gas giant, it is fairly difficult to quantify the exact temps.

Since Jupiter is a gas planet, there is no solid surface. If one stepped onto the planet, he would sink into it and eventually get crushed by the massive increase in pressure Jupiter's composition is nearly an exact copy of the Sun. There is about 82 % hydrogen, 18 % helium and traces of nearly all other elements.

The atmosphere appears as alternating bands of light regions, called zones, and dark regions called belts, that run parallel to the equator. The zones are higher in altitude than the belts, and are correspondingly lower in temperature.

Jupiter has 63 confirmed moons The most massive of them, the four Galilean Moons, were discovered in 1610 by Galileo Galilei and were the first objects found to orbit a body that was neither Earth nor the Sun They are the largest of the many moons of Jupiter and derive their names from the lovers of Zeus: Io, Europa, Ganymede and Callisto MOOOONS!!

Jupiter has no solid rock surface. One theory pictures a gradual transition from the outer ammonia clouds to a thick layer of frozen gases and finally to a liquid or solid hydrogen mantle. Beneath that Jupiter probably has a core of rocky material with a mass 10–15 times that of the earth Outer Ammonia Clouds Layer of Frozen Gases Liquid or Solid Hydrogen Mantle Rocky Material Core

clouds associated with the Spot appear to be about 8 km above neighboring cloud tops The Great Red Spot is a great anti-cyclonic (high pressure) storm like a hurricane on Earth the rotation is counterclockwise color is actually pink to orange three Earths would fit in it with room to spare.

You wouldn’t be able to walk on Jupiter, since there is no solid surface. You’d fall right through the ammonia clouds, and dive towards the center. You would eventually explode under all of the immense pressure There is a possibility of producing a space station that could orbit around Jupiter, since Jupiter’s magnetic field could give the space station enough energy.

Life on Jupiter would look very cloudy because of all the gases that are on the planet. The gases are which make up the atmosphere. The weather would have many storms. But in the night you will see the light from Jupiter's many moons.

Jupiter was discovered by the Italian scientist, Galileo which was the first astronomer to view Jupiter through a telescope. Jupiter is a gas planet that has a very stormy atmosphere. Jupiter has no solid rock surface. Beneath that Jupiter probably has a core of rocky material with a mass 10–15 times that of the earth. If you could go to Jupiter you’d fall right through the ammonia clouds, and dive towards the center. You would eventually explode under all of the immense pressure. Jupiter has a very strong magnetic field.
