Gas giant planets

  1. 1. Gas Giant Planets<br />By Kate, Roshan and Sophia<br />
  2. 2. What are the Gas Giant Planets?<br />The Gas Giant planets aka the Jovian Planets are a group of planets (Jupiter, Saturn, Uranus and Neptune) <br />They have the lowest temperature in the solar system and the lowest density<br />Photograph courtesy NASA/JPL/Space Science Institute<br />
  3. 3. What are Gas Giant planets made of?<br />Gas Giant Planets like Jupiter and Saturn are almost made of entirely gas. <br />In the center of these planets Is what scientists call a rocky center, this is misleading because in the center they have liquid compounds and molten metals. <br />Gas giant planets have a low density because they are comprised of mainly gas. <br />Gas giant planets are made of various gases such as hydrogen and helium. <br />
  4. 4. What is the inside of a gas Giant Planet look like?<br />"Neptune." The World Book Student Discovery Encyclopedia. Chicago: World Book, Inc., 2005.<br />
  5. 5. The Scale of Gas Giants<br />Gas giants are the largest planets in our solar system<br />They’re the lowest density planets<br />Jupiter is the biggest planet in the solar system with it’s diameter is 11 times the diameter of earth.<br />
  6. 6. Rotation and Axes<br />Gas Giant Planets have a very quick rotation are the sun. They also have very quick day ranging from 10 hours to 17 hours. <br />This has an effect on the planets shape because the faster the rotation the more flat the poles on the planes are. <br />The Jovian planets also have a 7 degree tilt.<br />
  7. 7. How where Jovian Planets formed?<br />The Jovian planets, also known as the “Gas Giants” were formed like any other planets except they formed earlier. They’re many hypotheses that explain this matter. <br />One of them is called the Nebular hypothesis.  The Nebular hypothesis involves a nebulae, a giant cloud of gas & dust. The nebulae is pulled by gravity which causes it to collapse into a rolling disk that is flat. Then it merged into the sun and planets.  Another hypothesis is a similar one to the Nebular hypothesis but it is called the Proto-planet hypothesis. The Proto-planet hypothesis includes a nebulae collapsing and the dust particles will stick together. The Jovian planets’ evolution was more evolved and it started earlier.            <br />
  8. 8. How where Jovian planets Discovered?<br />    The discovery of the Jovian planets were spaced out a lot through time.<br />Jupiter, for example was discovered a really long time ago by the Romans. <br />Also, another planet that was discovered a long time ago was Saturn. Saturn was visible in the night so the people who saw it were the people who discovered it. <br /> Uranus, also found a long time ago, was discovered by William Herschel in 1781. In 146, Johann Gelle discovered Neptune.<br />
  9. 9. What are the atmospheres of Jovian Planets like?<br />Each planet has distinct cloud layers<br />Jupiter and Saturn have their atmosphere’s made up of Ammonia clouds (150° K), Ammonium Hydrosulfide clouds (200° K) and Water clouds (270° K)<br />Uranus and Neptune have their clouds made up of Methane clouds (75 K)<br />
  10. 10. What is the Density of the Jovian planets like?<br />
  11. 11. What is a Jovian planet?<br />A Jovian planet is a large planet not mainly composed of rock and other solid material.<br />Jovian planets are made up of many gases, primarily hydrogen and helium.<br />Jovian planets are much larger and farther from the sun than terrestrial planets.<br />The four Jovian planets in our solar system are Jupiter, Uranus, Neptune, and Saturn.<br />Jovian planets have a very low density and a large diameter.<br />
