Transcript of "Planets of the solar system kevin yu"

  1. 1. Planets of the Solar System By: Kevin Yu Science 8C
  2. 2. General Information <ul><li>All the planets in The Milky Way revolve around the sun. ( Circling around) </li></ul><ul><li>Most/all the planets and moon rotate on themselves. ( Spin on own axis) </li></ul><ul><li>All these planets have their own gravity, the bigger the mass is the more gravity a planet/moon has. </li></ul><ul><li>A mass will become a planet if it has a round enough shape, revolves around the sun, and has its own gravity. </li></ul>
  3. 3. Inner/Outer Planets <ul><li>There are 8 planets in our solar system, Mercury, Venus, Earth, and Mars are inner planets, and Jupiter, Saturn, Uranus, and Neptune are the outer planets, as well as 3 dwarf planets. </li></ul><ul><li>These inner and outer planets are seperated by the asteroid belt. </li></ul><ul><li>Inner planets are often filled with craters from the many asteroids crashing it. </li></ul><ul><li>While inner planets are made of solid rock, outer planets are mostly made out of gases. </li></ul>
  4. 4. Inner Planets
  5. 5. Mercury <ul><li>Mercury’s atmosphere is not substantial because it’s too close to the sun, and it contains helium and sodium. </li></ul><ul><li>Mercury is the closest to the sun. It can reach up to 427 ° c when facing the sun, and below -183 °c when facing away from the sun. </li></ul><ul><li>Mercury has no atmosphere and is shaped by volcanos, tectonic plates, and asteroid and meteor impacts. </li></ul>
  6. 6. Venus <ul><li>Venus is also known as “The Evening Star” from Earth because of the light its cloud reflects. </li></ul><ul><li>A year in venus is even longer than a day at venus because of its slow rotation. Venus has a retrogade rotation, meaning it rotates the opposite direction from Earth, resulting the sun to rise from west to east there. </li></ul><ul><li>You would think Mercury is the hottest planet since it’s closest to the sun, but Venus is. Its greenhouse effect traps the heat in the planet. </li></ul>
  7. 7. Earth <ul><li>Our atmosphere contains 21% oxygen, 78% nitrogen, 0.9% argon, and 0.1% other elements. The atmosphere protects us from solar radiation and most meteors. </li></ul><ul><li>Earth lies on a 23.5 degree angle tilt, giving us seasonal variations. Earth also has a magnetic field produced from the molten metal inside Earth, and Earth’s fast rotation. </li></ul><ul><li>The Moon is the natural satellite of Earth and is often seen at night. </li></ul>
  8. 8. Mars <ul><li>M ars looks generally red because of the iron rich soil laying there. </li></ul><ul><li>Mars is also believed to have life because of tiny bacteria found from there. </li></ul><ul><li>95% of Mars’s atmosphere is carbon dioxide. </li></ul><ul><li>Mars also has the largest volcano in our solar system which is “Olympus Mons”. It is 26KM tall. </li></ul><ul><li>Mars also has 2 natural satallites which are Phobos and Deimos. </li></ul>
  9. 9. Outer Planets
  10. 10. Jupiter <ul><li>Its flat poles and bulgy equator makes it rotate very fast. </li></ul><ul><li>Jupiter’s atmosphere contains hydrogen, helium, sulfur, and nitrogen. </li></ul><ul><li>There is a giant red spot on Jupiter believed by scientists to be a huge hurricane. </li></ul><ul><li>Jupiter has over 50 natural satellites and one of them, Io, has volcanic activity on it. </li></ul>
  11. 11. Saturn <ul><li>Saturn’s atmosphere consists of hydrogen and helium. </li></ul><ul><li>Saturn has a large rings of ice and dust believed to be formed by the break up of nearby satellites. </li></ul><ul><li>Saturn has long seasons because it takes about 29.5 years to complete on revolution. </li></ul><ul><li>Saturn has such a low density, it can even float on water. </li></ul>
  12. 12. Uranus <ul><li>Uranus, unlike other planet has a tilt of 98 ° and practically rotates horizontally. </li></ul><ul><li>Uranus’s atmosohere includes hydrogen, helium and methane. </li></ul><ul><li>Uranus has up to 27 known natural satellites. </li></ul>
  13. 13. Neptune <ul><li>Neptune has an atmosphere of ammonia, helium, and methane. </li></ul><ul><li>Neptune has 13 known natural satellites. </li></ul><ul><li>Neptune’s largest natural satellite is Triton, and is believed that it is not originally Neptune’s satellite until Neptune’s gravitational pull grabbed Triton in its orbit. </li></ul>
  14. 14. Dwarf Planets
  15. 15. Dwarf Planets <ul><li>A dwarf planet is a planet that fails the third requirement of being a planet: Having its own gravity. </li></ul><ul><li>There are lots of dwarf planets, three of the more known ones are: Pluto, Ceres, and Eris. </li></ul><ul><li>Pluto used to be an outer planet. </li></ul>
  16. 16. Pluto <ul><li>Pluto has 3 natural satellites, Charon, Nix, and Hydra. </li></ul><ul><li>Scientists using a spectroscope have found that Pluto’s atmosphere contains methane and nitrogen. </li></ul><ul><li>It is also been found that one of Pluto’s satellites, Charon, shares the same atmosphere with Pluto. </li></ul>
  17. 17. Ceres <ul><li>Ceres takes 4.6 years to finish one revolution around the sun. </li></ul><ul><li>Ceres was once thoght as an asteroid, because it is located in the asteroid belt. </li></ul><ul><li>Ceres’s surface is covered with things lyk ice, water, carbonates, and clay. </li></ul>
  18. 18. Eris <ul><li>Eris was originally named Xena and has a natural satellite named Dysnomia. </li></ul><ul><li>It takes up to 577 years to complete one revolution! </li></ul><ul><li>Eris was originally not considered a planet until the category of “Dwarf Planets” came out. </li></ul>
