__How Jupiter got it's name:__ Ancient astronomers named Jupiter after the king of the roman gods

__Discovery of Jupiter:__ Who: Ancient Babylonians When:Original date is unknown but it was discovered by the rest of the world on January 7, 1610 How:They could see it in the night sky in the ancient days Where: Babylonia

Distances: Order from the sun:Jupiter is the fifth closet planet to the sun Distance from the sun: 778,330,000 kilometers from the sun Distance from the earth: 365 million miles

Planet measurements: Mass: Jupiter has a mass that is 318 times greater than the Earth's. It's mass is also about two and a half times greater than all of the planets combined. Volume:Jupiter's volume is large enough to contain 1 300 planets the size of Earth.

Orbit and Rotation: <span style="font-family: 'Times New Roman',Times,serif;">Number of days to orbit around the sun:it takes 12 Earth years for Jupiter to complete an orbit around the sun. <span style="font-family: 'Times New Roman',Times,serif;">Perihelion (how close it gets to the sun):740,573,600 kilometers

<span style="font-family: 'Times New Roman',Times,serif;">Equatorial Circumference: 449,197 kilometers <span style="font-family: 'Times New Roman',Times,serif;">Mean Density: 1.326 g/cm^3 <span style="font-family: 'Times New Roman',Times,serif;">Gravity:Jupiter is the largest planet and therefore has the most intense gravity. It's gravity is 2.5 times what it is here on Earth.

<span style="font-family: 'Times New Roman',Times,serif;">Aphelion (how far does it get from the sun?): 816,520,800 kilometers <span style="font-family: 'Times New Roman',Times,serif;">Length of one day (number of hours in one day)?: 9.8-10 hour long days

<span style="font-family: 'Times New Roman',Times,serif;">Planet Appearance: The vivid colors are probably a chemical reaction of sulfur whose compounds take on a wide variety of colors. The Great Red Spot on Jupiter is an ongoing storm. Also, the light colored bands are called zones while the dark ones are called belts.

<span style="font-family: 'Times New Roman',Times,serif;">Jupiter has a ring just like Saturn and Uranus. There are four separate parts of the ring. These parts are the halo ring, the main ring, Amalthea gossamer ring and the Thebe gossamer ring.These rings were discovered by Voyager 1 in 1979.

<span style="font-family: 'Times New Roman',Times,serif;">Satellites: The planet has over 60 known satellites (moons) but most of them are extremely small and faint. Some of these are: <span style="font-family: 'Times New Roman',Times,serif;">Euopa, Ganymeda, Io, Callisto, Metis, Adrastea, Amalthea, Thebe, Leda, Himalia, Lysithea, Elara, Ananke, Carme, Pasiphae, and Sonope

<span style="font-family: 'Times New Roman',Times,serif;">Composition: <span style="font-family: 'Times New Roman',Times,serif;">Core composition: Surface composition: <span style="font-family: 'Times New Roman',Times,serif;">Jupiter has a rocky core that Liquid hydrogen and helium <span style="font-family: 'Times New Roman',Times,serif;">also has some iron in it

<span style="font-family: 'Times New Roman',Times,serif;">Atmosphere: <span style="font-family: 'Times New Roman',Times,serif;">__Major gases:__ <span style="font-family: 'Times New Roman',Times,serif;">84% hydrogen <span style="font-family: 'Times New Roman',Times,serif;">15% Helium <span style="font-family: 'Times New Roman',Times,serif;">__Minor gases:__ <span style="font-family: 'Times New Roman',Times,serif;">acetylene phosphine <span style="font-family: 'Times New Roman',Times,serif;">ammonia <span style="font-family: 'Times New Roman',Times,serif;">ethane <span style="font-family: 'Times New Roman',Times,serif;">methane <span style="font-family: 'Times New Roman',Times,serif;">water vapor

<span style="font-family: 'Times New Roman',Times,serif;">Surface condition: <span style="font-family: 'Times New Roman',Times,serif;">__Wind speeds:__ <span style="font-family: 'Times New Roman',Times,serif;">In the ongoing storm <span style="font-family: 'Times New Roman',Times,serif;">on Jupiter the wind is <span style="font-family: 'Times New Roman',Times,serif;">as fast as 270 miles <span style="font-family: 'Times New Roman',Times,serif;">per hour. <span style="font-family: 'Times New Roman',Times,serif;">__Temperature ranges:__ <span style="font-family: 'Times New Roman',Times,serif;">The temperature is <span style="font-family: 'Times New Roman',Times,serif;">approximately -270 <span style="font-family: 'Times New Roman',Times,serif;">degrees Fahrenheit. <span style="font-family: 'Times New Roman',Times,serif;">__Surface pressure:__ <span style="font-family: 'Times New Roman',Times,serif;">There is no solid <span style="font-family: 'Times New Roman',Times,serif;">surface. It is so <span style="font-family: 'Times New Roman',Times,serif;">tiny it is less than <span style="font-family: 'Times New Roman',Times,serif;">per hour. 1%.

<span style="font-family: 'Times New Roman',Times,serif;">Weather: <span style="font-family: 'Times New Roman',Times,serif;">The weather on Jupiter is very unique. There is a storm on Jupiter that has been ongoing for over 300 years.

<span style="font-family: 'Times New Roman',Times,serif;">Water: <span style="font-family: 'Times New Roman',Times,serif;">Under Jupiter's atmosphere is a large liquid ocean of hydrogen and water. There is even possible liquid water.

<span style="font-family: 'Times New Roman',Times,serif;">Exploration: <span style="font-family: 'Times New Roman',Times,serif;">Jupiter's rings were first discovered by //Voyager 1// in1979. //Pioneer 10// was the first spacecraft to travel to Jupiter. Some others are: <span style="font-family: 'Times New Roman',Times,serif;">//Pioneer 11//, //Voyager 2//, and //Ulysses//.

<span style="font-family: 'Times New Roman',Times,serif;">Habitability: <span style="font-family: 'Times New Roman',Times,serif;">If people traveled to Jupiter they would freeze, suffocate, or get sguished by Jupiter's gravity.

<span style="font-family: 'Times New Roman',Times,serif;">Future human travel: <span style="font-family: 'Times New Roman',Times,serif;">Problem=There is not enough oxygen <span style="font-family: 'Times New Roman',Times,serif;">Solution=Oxygen tanks

<span style="font-family: 'Times New Roman',Times,serif;">Problem=It is too cold <span style="font-family: 'Times New Roman',Times,serif;">Solution=Warmers in the spacesuits

<span style="font-family: 'Times New Roman',Times,serif;">Terraforming: <span style="font-family: 'Times New Roman',Times,serif;">There needs to be better oxygen <span style="font-family: 'Times New Roman',Times,serif;">It needs to be warmer

<span style="font-family: 'Times New Roman',Times,serif;">Cool facts: <span style="font-family: 'Times New Roman',Times,serif;">Weight: <span style="font-family: 'Times New Roman',Times,serif;">If you weigh 100 pounds on earth you would weigh 234 pounds on Jupiter. Multiply your weight by 2.34.

<span style="font-family: 'Times New Roman',Times,serif;">3 cool facts about Jupiter: <span style="font-family: 'Times New Roman',Times,serif;">1.Jupiter is so big that all of the other planets would fit inside of it. <span style="font-family: 'Times New Roman',Times,serif;">2.Jupiter is about the same age as the sun- 4.5 billion years old. <span style="font-family: 'Times New Roman',Times,serif;">3. The diameter of Jupiter is approximately 133708kilometers from pole to pole and142984 kilometers at the equator.
