  • GAS GIANTS By: Hanna, Skylar, & Tsephell
  • GENERAL:• There are four gas giants (Jovian Planets, Giant Planets) in our Solar System – Jupiter, Saturn, Uranus, and Neptune.• The outer planets of the Solar System -Cold, due to the distance from the Sun.• Compared to other terrestrial planets, they are massive.• Not completely gas, the core is liquid compounds (including heavy molten liquids)• Low-density• Density increases towards the center• Rotate quickly• Solid moons• Two type of gas planets: - Classic or traditional (mostly hydrogen and helium) - Ice gas planets (a little hydrogen and helium, and are mostly made out of iceslike methane, ammonia, and water)
  • JUPITER• Discovered by the Greeks• Biggest planet in the solar system• Stormy and Cold - Has swirling cloud stripes caused by massive storms, that have been there forhundreds of years.• Orbit- 11.87 years to orbit around the Sun• 50 moons (Europa, Io, Ganymede, Callisto, & Amalthea are the biggest moons)• Three rings: -The Main Ring (Darkest) -The Halo -Gossamer (Faintest)• The pressure and temperature increase, compressing the hydrogen gas into a liquid. A third of the way down, the hydrogen becomes metallic and starts to conduct electric.• Jupiters powerful magnetic field is generated by electrical currents driven by Jupiters fast rotation, the pressure may support a solid core of rock about the size of Earth.• Has enough gas to resemble a stars composition, but doesnt have enough gas to ignite like a star (needs to be 80x larger).• Enormous magnetic field is nearly 20,000 times as powerful as Earths.
  • SATURN• Discovered in 1610• Orbit- 27.9 years• 53 moons• Atmosphere: -72% hydrogen - 25% helium - Little bit of methane and ice• 23 rings (6 visible rings)• These super-fast winds, combined with heat rising from within the planets interior, cause the yellow and gold bands visible in the atmosphere. -The rings are mostly made of water ice• The rings are believed to be pieces of comets, asteroids or shattered moons that broke up before they reached the planet. Each ring orbits at a different speed around the planet.• Stormy and Warm
  • URANUS• Discovered in 1781• Seventh planet from the Sun• Third largest planet• Orbit- 84.3 years• 27 moons• Atmosphere: -83% hydrogen -15% helium -2% methane• 13 rings (are not visible)• Icy and cold• Clouds that blow around rapidly -made of methane ice• The blue color is because of methane gas in the atmosphere• Has only been visited by Voyager 2 in 1986
  • NEPTUNE• Discovered in 1846• Strongest winds than any other planet in the solar system (1500 M.P.H)• Orbit- 146 years• Orbit defies Newton’s first law• 13 known moons• Nine rings (none are visible to the human eye)• Atmosphere: -Hydrogen -Helium -Methane• Icy• Has on been visited by Voyager 2 (1989)
