Solar system

  1. 1. SOLAR SYSTEM<br />Planet Webquest<br />
  2. 2. General Info<br />Revolution- a small object going around a bigger object<br />Rotation- an object spinning on its axis.<br />8 planets + 5 dwarf planets in our solar system<br />Inner planets:<br />Mercury<br />Venus<br />Mars<br />Earth<br />Outer planets:<br />Jupiter<br />Saturn<br />Uranus<br />neptune<br />
  3. 3. General Info (cont)<br />Differences between inner and outer planets<br />There are more craters on the inner planets because the outer planets are not solid, therefore impact with smaller objects is impossible<br />Orbit- a path followed by a planet/satellite as it revolves around a larger object<br />
  4. 4. General info (cont 2)<br />To be considered a planet, need to meet 3 requirements:<br />Revolve around the sun<br />Have enough mass to turn round because of gravity<br />Clears out objects in its path<br />Dwarf planet- a body that meets the first 2 requirements but not the third one<br />Dwarf planets:<br />Pluto<br />Ceres<br />Eris<br />Haumea<br />Makemake<br />
  5. 5. THE INNER PLANETS<br />Mercury, Venus, Earth, Mars<br />
  6. 6. Mercury<br />It has no substantial atmosphere because it’s so tiny.<br />Atmosphere is composed of helium and sodium. <br />Three processes shaped mercury:<br />Impact cratering<br />Volcanism<br />Tectonic activity<br />
  7. 7. Venus<br />Aka. The evening star because it is the brightest planet that could be viewed from earth.<br />Atmosphere is composed of carbon dioxide and sulfuric acid<br />Retrograde rotation- it rotates in the opposite direction as the other planets<br />It rotates really slow, so a day is longer than a year.<br />It spins the wrong way, so on Venus the sun rises in the west and sets in the east.<br />It’s greenhouse effect makes it the hottest planet in the solar system.<br />
  8. 8. Earth<br />Atmosphere:<br />21% oxygen<br />78% nitrogen<br />0.9% argon<br />0.1% other gases<br />Our atmosphere protects us from meteorites and the sun's harmful waves.<br />Tilts at a 23.5o angle.<br />The magnetic field is produced by the Earth’s rotation and it’s metal core.<br />Has a natural satellite called “The Moon”, plus lots of artificial ones.<br />
  9. 9. Mars<br />Scientists study little pieces of rock from mars to try and find sign of life.<br />Atmosphere is mostly carbon dioxide.<br />It appears red because of the rusty iron on the surface.<br />Olympus Mons is the largest volcano in the solar system. It is on mars.<br />To small moons:<br />Phobos<br />Deimos<br />
  10. 10. THE OUTER PLANETS<br />Jupiter, Saturn, Uranus, Neptune<br />
  11. 11. Jupiter<br />It rotates really fast so the equator bulges while the ends are flatter<br />Atmosphere<br />Hydrogen<br />Helium<br />Sulfur<br />Nitrogen<br />Giant red spot- a huge hurricane that has been there since almost forever ago<br />Has at least 63 moons (more to be discovered)<br />Io is volcanic, and the hot spots are hotter than any other body in the solar system.<br />
  12. 12. Saturn<br />Atmosphere:<br />Hydrogen<br />Helium<br />Rings are caused by the breakup of old moons.<br />Rings are made of water ice and dust.<br />Saturn is very light, could float on water<br />Seasons on Saturn last 30 times longer than seasons on earth.<br />
  13. 13. Uranus<br />It rotates on its side<br />Atmosphere:<br />Hydrogen<br />Helium<br />Methane<br />27 known satellites.<br />
  14. 14. Neptune<br />Atmosphere:<br />Ammonia<br />Helium<br />Methane<br />On the question sheet it asks how many moons does Uranus have. I assume that it is a typo and it was meant to ask how many moons does Neptune have.<br />13 known natural satellites<br />Triton might originally be a dwarf planet, or moon of Uranus, or moon of Pluto, or something else that got sucked into Neptune's gravitational pull<br />
  15. 15. DWARF PLANETS<br />Pluto, Ceres, Eris<br />
  16. 16. Pluto<br />Moons:<br />Charon<br />Nix<br />Hydra<br />By using a spectroscope, scientists detected methane frost on Pluto and water frost on Charon. <br />Charon is half the size of pluto<br />
  17. 17. Ceres<br />One revolution= 4.6 earth years<br />It is among lots of asteroids so it was considered an asteroid for a period of time.<br /> Water ice, carbonates, and clays can be found on the surface<br />
  18. 18. Eris<br />Old name is Xena<br />One revolution= 557 earth years<br />Moon= Dysnomia<br />It did not clear out its orbit so it is not considered a planet. <br />
