Cindy's Solar System PPY

  1. 1. Solar system web quest<br />By: Cindy Chang 8C<br />
  2. 2. The general facts<br />Revolve: To revolve is to complete an orbit around an object<br />Rotate: To rotate is to circle around your center<br />Orbit: To travel in a curved path around an object<br />Currently there are now 8 planets in the solar<br />The inner planets include Mercury, Venus, Earth and Mars<br />The outer planets include Jupiter, Saturn, Uranus, and Neptune<br />The inner planets are mainly made up of rock and dirt, while the outer planets are made up of gas balls<br />In the first 600 million years which inner planets existed, they were constantly being hit by meteoroids<br /> To be a planet, an object must have a round shape due to its gravity, orbit around the sun, and its orbit path must not have stuffs that are about its own size floating around<br />A dwarf planet is a planet that meets the first 2 requirements but not the third one<br />Three dwarf planets are Pluto, Eris, and Ceres<br />
  3. 3. Mercury<br />Mercury's atmosphere is caused by the heating of the sun - the sun heated mercury so much that its atmosphere is very thin.<br />Mercury's atmosphere is consisted of sodium and helium.<br />Objects striking the surface of mercury making craters, lava on the surface because of volcanoes, and the crust of mercury <br />moving so that mercury can adjust to the contraction it has shaped mercury.<br />
  4. 4. Venus<br />Venus is called the evening star because when you look from earth it is considered the brightest planet that could be seen.<br />The clouds in Venus reflects the sun's light.<br />You can find carbon dioxide and sulfuric acid in Venus.<br />Retrograde rotation is rotation in which that the planet rotates in a clockwise direction unlike other planets.<br />A Venus day lasts longer than a Venus year because its rotation is slower than its revolution! Rotating takes 243 Earth days, and<br />a revolution takes 225 Earth days.<br />The sun seems to rise in the west and set in the east because it rotates clockwise unlike the other planets so the sun comes out<br />in the west.<br />Venus is the hottest planet in your solar system because its atmosphere acts like a green house which traps the heat that is <br />from the sun.<br />
  5. 5. Earth<br />Earth's atmosphere consists of 21% oxygen, 78% nitrogen, 0.9% argon, and 0.1% of other gases.<br />Earth’s atmosphere protects us from solar radiation and meteors who are trying to crash into Earth at anytime.<br />The rotational tilt of Earth is 23.5 degrees.<br />The rapid spin of Earth with a hot core produces Earth’s magnetic field.<br />The satellite of Earth is the Moon.<br />
  6. 6. Mars<br />Pieces of meteorites found in Earth from Mars had traces of bacteria, so life may have existed in Mars in the past.<br />The atmosphere of Mars is mostly made of carbon dioxide.<br />Mars appears to be red because of its iron in Mar’s soil.<br />Olympus Mons is the largest volcano in Mars.<br />Phobos and Deimos are the two satellites on Mars.<br />
  7. 7. Jupiter<br />Jupiter had such a rapid rotation that its equator bulged and its poles were flattened.<br />Sulfur, helium, nitrogen, and hydrogen are believed to be components of Jupiter’s atmosphere.<br />A huge storm that looks like a hurricane in Jupiter is the Giant Red Spot.<br />Jupiter had 63 natural satellites.<br />One of Jupiter’s satellites called Io has active volcanoes on it.<br />
  8. 8. Saturn<br />Hydrogen and helium makes up Saturn’s atmosphere. <br />The leftovers of meteoroids which crashed into Saturn caused Saturn to have rings.<br />Ice and dust make up Saturn’s rings.<br />Saturn’s low density makes it float in water.<br />Seasons on Saturn lasts more than 7 Earth years.<br />
  9. 9. Uranus<br />Uranus is tilted 98 degrees, therefore it looks like that it is rotating on the sides unlike other planets.<br />Hydrogen, helium and methane makes up Uranus's atmosphere.<br />It is known that Uranus has 27 satellites revolving around it.<br />
  10. 10. Neptune<br />Neptune’s atmosphere contains helium, methane, and ammonia.<br />Neptune has 13 known satellites.<br />Triton is the largest satellite of Neptune. Astronomers guessed that Triton was being forced into Neptune’s gravity, so it became an orbiting satellite like that.<br />
  11. 11. Pluto<br />Pluto’s three moons are Nix, Hydra, and Charon.<br />Scientists have detected frozen methane on Pluto and frozen water on Charon.<br />Charon is a bit bluer than Pluto, and it snows frosts when Pluto is farthest from the sun.<br />
  12. 12. Ceres<br />Ceres’ revolution around the sun once takes about 4.6 Earth years.<br />It was considered as an asteroid in the past because it is located in the middle of the asteroid belt.<br />You can find water, ice, carbonates and clay on Ceres.<br />
  13. 13. Eris<br />Eris’s original name was Xena, a popular TV show at the time when it was founded.<br />If Eris orbited the sun once, 557 Earth years would pass.<br />Eris’s moon is called Dysnomia.<br />Eris isn’t considered to be a planet because it has random unidentified ‘stuffs’ around its orbit path that it hasn’t cleared yet <br />
