The Nine Planets

  2. 2. Can you name the NINE planets?
  3. 3. The NINE planets
  4. 4. Mercury
  5. 5. Venus <ul><li>Venus is the second planet from the Sun, and the sixth largest of all the nine planets. </li></ul><ul><li>Venus' hot temperature is due to what we call &quot;the Greenhouse Effect.&quot; The large amount of carbon dioxide in Venus' atmosphere acts like a blanket. The heat gets trapped underneath the thick layer of clouds. Because the heat has nowhere to go, Venus gets hotter and stays hot. </li></ul>
  6. 6. Earth <ul><li>Average Distance From Sun </li></ul><ul><li>Kilometers: 149,600,000 </li></ul><ul><li>Miles: 93,000,000 </li></ul><ul><li>Astronomical Units: 1.000 </li></ul><ul><li>Length of Year : 365.26 days </li></ul><ul><li>Length of Day : 23 hours 56 minutes 4 seconds </li></ul><ul><li>Average Orbital Speed </li></ul><ul><li>Kilometers/Second: 29.79 </li></ul><ul><li>Miles/Second: 18.51 </li></ul><ul><li>Equatorial Diameter </li></ul><ul><li>Kilometers: 12,756 </li></ul><ul><li>Miles: 7,926 </li></ul><ul><li>Earth=1: 1.000 </li></ul><ul><li>Mass (Earth=1): 1.000 </li></ul><ul><li>Volume (Earth=1): 1.000 </li></ul><ul><li>Number of Known Satellites : 1 </li></ul><ul><li>The Earth is a small, rocky planet which supports a variety of life. As far as we know, Earth is unique from all other planets in this respect. </li></ul><ul><li>The Earth moves around the sun, taking one year to go around once. The moon goes around the Earth. It is smaller than the sun, but it looks as big as the sun because it is much closer to us. </li></ul>
  7. 7. Earth’s Moon <ul><li>The moon is roughly one sixth the size of Earth. It rotates around Earth every twenty-seven days, seven hours, and forty-three minutes. However, we only see one side of it because the other side never faces the Earth. </li></ul><ul><li>Several Americans have walked on the moon as part of the Apollo space program. </li></ul><ul><li>Average Distance From Earth </li></ul><ul><li>Kilometers: 384,500 </li></ul><ul><li>Miles: 238,900 </li></ul><ul><li>Astronomical Units: 0.0026 </li></ul><ul><li>Length of Year (To Orbit Earth): 27.32 days </li></ul><ul><li>Length of Day: 27 days 7 hours 43 minutes </li></ul><ul><li>Average Orbital Speed </li></ul><ul><li>Kilometers/Second: 1.023 </li></ul><ul><li>Miles/Second: 0.636 </li></ul><ul><li>Equatorial Diameter </li></ul><ul><li>Kilometers: 3,476 </li></ul><ul><li>Miles: 2,160 </li></ul><ul><li>Earth=1: 0.24 </li></ul><ul><li>Mass (Earth=1): 0.012 </li></ul><ul><li>Volume (Earth=1): 0.020 </li></ul>
  8. 8. Moon Picture <ul><li>This picture shows you how the size of the Earth compares to the size of the moon. </li></ul>
  9. 9. Astronauts left the American flag on the moon.
  10. 10. Mars <ul><li>Mars is a small, rocky planet. There are no seas and it is always very cold. The air is so thin that we could not breath it. It is smaller than the Earth, though bigger than our moon. </li></ul><ul><li>Mars has permanent ice caps at both poles made up mostly of solid carbon dioxide. We know this as &quot;dry ice.&quot; Very strong winds and vast dust storms sometimes blow through the entire planet for months! </li></ul><ul><li>Mars has two tiny moons which orbit very close to the surface. Their names are Phobos and Deimos. </li></ul>
  11. 11. Jupiter <ul><li>Jupiter is the fifth planet from the Sun and by far the largest of all nine planets. </li></ul><ul><li>Jupiter is not like Earth. It is made up of gases, so we could never land a rocket there. </li></ul><ul><li>Jupiter's most outstanding and interesting feature is called &quot;The Great Red Spot&quot;, which is a huge storm in Jupiter's gas. </li></ul>
  12. 12. Jupiter’s GREAT red spot <ul><li>This is a huge storm that has been going for decades!!! </li></ul>
  13. 13. Jupiter’s Rings <ul><li>Jupiter has very faint rings. They are much more difficult to see than the rings of Saturn. </li></ul>
  14. 14. Saturn <ul><li>Saturn is the sixth planet from the Sun, and the second largest of the nine planets. Like Jupiter, Saturn has a surface made up of gas. </li></ul><ul><li>Saturn has rings around it, which are made of little bits of ice moving around Saturn.  Saturn has eighteen moons that we know of. </li></ul><ul><li>Average Distance From Sun </li></ul><ul><li>Kilometers: 1,427,000,000 </li></ul><ul><li>Miles: 886,700,000 </li></ul><ul><li>Astronomical Units: 9.539 </li></ul><ul><li>Length of Year: 29.46 years </li></ul><ul><li>Length of Day: 10 hours 39 minutes 24 seconds (at equator) </li></ul><ul><li>Average Orbital Speed </li></ul><ul><li>Kilometers/Seconds: 9.64 </li></ul><ul><li>Miles/Second: 5.99 </li></ul><ul><li>Equatorial Diameter </li></ul><ul><li>Kilometers: 120,000 </li></ul><ul><li>Miles: 74,565 </li></ul><ul><li>Earth=1: 9.44 </li></ul><ul><li>Mass (Earth=1): 95.15 </li></ul><ul><li>Volume (Earth=1): 833 </li></ul><ul><li>Number of Known Satellites: 22 (plus rings) </li></ul>
  15. 15. Uranus <ul><li>Average Distance From Sun </li></ul><ul><li>Kilometers: 2,870,000,000 </li></ul><ul><li>Miles: 1,783,000,000 </li></ul><ul><li>Astronomical Units: 19.18 </li></ul><ul><li>Length of Year: 84.01 years </li></ul><ul><li>Length of Day: 17 hours 14 minutes ? seconds (Retrograde) </li></ul><ul><li>Average Orbital Speed </li></ul><ul><li>Kilometers: 6.81 </li></ul><ul><li>Miles: 4.23 </li></ul><ul><li>Equatorial Diameter </li></ul><ul><li>Kilometers: 50,800 </li></ul><ul><li>Miles: 31,600 </li></ul><ul><li>Earth=1: 4.10 </li></ul><ul><li>Mass (Earth=1): 14.54 </li></ul><ul><li>Volume (Earth=1): 63.0 </li></ul><ul><li>Number of Known Satellites: 21 (plus rings) </li></ul><ul><li>Uranus is a cold, giant gas planet which is made up of mostly rock and various ices. Uranus has a faint ring system and 21 known moons. </li></ul><ul><li>Uranus is a very odd planet. It sits on its side with the north and south poles sticking out the sides. </li></ul>
  16. 16. Neptune <ul><li>Neptune is a cold, giant gas planet which is made up of mostly rock and various ices. Neptune is about half as big as Saturn and has eight known moons; seven small ones and a large moon called Triton.  </li></ul><ul><li>Neptune is usually the eighth planet from the Sun but occasionally the ninth planet Pluto crosses Neptune's orbit and becomes the &quot;eighth planet&quot;. </li></ul><ul><li>Its bluish color comes from its atmosphere of methane gas. </li></ul>
  17. 17. Pluto <ul><li>Pluto is the farthest planet from the Sun (usually) and by far the smallest of the nine planets.  </li></ul><ul><li>Discovered in 1930, Pluto has always appeared as nothing more than a dot of light in even the largest earth-based telescopes. The Hubble Space Telescope is able to get better images of this distant planet. </li></ul><ul><li>Pluto is 2/3 the size of Earth's Moon but 1,200 times farther away. Viewing surface detail is as difficult as trying to read the printing on a golf ball located thirty-three miles away! </li></ul><ul><li>Average Distance From Sun </li></ul><ul><li>Kilometers: 5,913,520,000 </li></ul><ul><li>Miles: 3,666,000,000 </li></ul><ul><li>Astronomical Units: 39.44 </li></ul><ul><li>Length of Year: 248.54 years </li></ul><ul><li>Length of Day: 6 days 9 hours 17 minutes </li></ul><ul><li>Average Orbital Velocity </li></ul><ul><li>Kilometers/Second: 4.74 </li></ul><ul><li>Miles/Second: 2.95 </li></ul><ul><li>Equatorial Diameter </li></ul><ul><li>Kilometers: 2,294 </li></ul><ul><li>Miles: 1,425 </li></ul><ul><li>Earth=1: 0.18 </li></ul><ul><li>Mass (Earth=1): 0.0022 </li></ul><ul><li>Volume (Earth=1): 0.013? </li></ul><ul><li>Number of Known Satellites: 1 </li></ul>
  18. 18. Pluto’s size <ul><li>This shows Pluto on the left and its moon Chiron on the right. By comparing them to the map of the United States, you can see how small they are. </li></ul>
