solar system

  1. 1. The Solar System By Ahmed, Youseff, Hannah, Ayah
  2. 2. Planet’s Formation <ul><li>The planets were formed by the Big Bang Theory, which was when all sorts of gases combined in one place, and a huge explosion occurred. Rocks formed, over a million of years they cooled down, and became planets, that was considered billions of years before any life was in the universe. Because of the Big Bang theory the universe will still expand, making new planets form!!! </li></ul>
  3. 3. The Order of Planets from the sun <ul><li>1.Mercury 2.Venus 3.Earth 4.Mars 5.Jupitor 6.Saturn 7.Uranus 8.Neptune </li></ul>
  4. 4. Mercury <ul><li>Types of temperature in </li></ul><ul><li>Mercury, the nearest planet form the sun, are </li></ul><ul><li>totally different than any other planets. The temperature </li></ul><ul><li>rises to 450 degrees Celsius, and at night it </li></ul><ul><li>goes to -180 degrees Celsius. Mercury is 58 million </li></ul><ul><li>kilometers away from the sun </li></ul><ul><li>and orbits around the sun for 88 </li></ul><ul><li>days. Mercury’s equator is about 3,024 miles, </li></ul><ul><li>and it takes 58.6 days to turn on its axis. </li></ul><ul><li>There is cliffs which are 2 </li></ul><ul><li>miles high, it shows that this had been </li></ul><ul><li>formed three billion years ago. Its surface is </li></ul><ul><li>filled with thousands of craters which was made of </li></ul><ul><li>meteors crashing into Mercury. </li></ul>
  5. 5. Venus <ul><li>Venus is a very interesting planet. Its </li></ul><ul><li>about the same size as Earth, and much </li></ul><ul><li>hotter than Mercury with about a difference </li></ul><ul><li>of 30 degrees Celsius. </li></ul><ul><li>The distance from the </li></ul><ul><li>sun is 108 million kilometers, and </li></ul><ul><li>255 days to have a full </li></ul><ul><li>circle around the sun, its equator is </li></ul><ul><li>about 7.504 miles, and it takes 243 days to </li></ul><ul><li>Turn on its axis. Its very </li></ul><ul><li>hard to see through the clouds </li></ul><ul><li>of Venus, they almost kept every </li></ul><ul><li>part of Venus hidden. The most </li></ul><ul><li>interesting part is that Venus actually </li></ul><ul><li>has thousands of volcanoes, and they may be </li></ul><ul><li>erupting right now! </li></ul>
  6. 6. Our Home Planet <ul><li>Earth is the is the biggest rocky planet in </li></ul><ul><li>the Solar System, and also the only planet that </li></ul><ul><li>has life on it, at least </li></ul><ul><li>that what we know until </li></ul><ul><li>now. Earth is similar to </li></ul><ul><li>other planets, it has </li></ul><ul><li>craters, which is similar to </li></ul><ul><li>Mercury, and it has similarities </li></ul><ul><li>with Venus such as the volcanoes. Earth is </li></ul><ul><li>150 million kilometers from the sun, and orbits </li></ul><ul><li>around for 365 days. Its equator is 7,909 </li></ul><ul><li>Miles. Earth is the nearest planet to the sun </li></ul><ul><li>which has a moon orbit around it. Earth has </li></ul><ul><li>about 70% of water, that’s one of the reasons we can </li></ul><ul><li>live in this planet. Also Earth has 21% oxygen </li></ul><ul><li>, and 78% nitrogen, all sorts of organisms </li></ul><ul><li>depend on them. </li></ul>
  7. 7. Mars <ul><li>If you saw Mars you would say its a </li></ul><ul><li>desert while its much </li></ul><ul><li>bigger than that. The </li></ul><ul><li>Atmosphere is mainly </li></ul><ul><li>carbon dioxide. The </li></ul><ul><li>temperatures rise to </li></ul><ul><li>20 degrees Celsius, but </li></ul><ul><li>usually it lowers lesser </li></ul><ul><li>than -23 degrees Celsius. </li></ul><ul><li>Mars billion years ago it was very different </li></ul><ul><li>, the atmosphere was much more thicker, there </li></ul><ul><li>was erupting volcanoes, and there is several </li></ul><ul><li>volcanoes now located in the northern </li></ul><ul><li>hemisphere, but there are not erupting no longer. Some </li></ul><ul><li>Astronomers believe there would be microscopic </li></ul><ul><li>Organisms living there from the many similarities it </li></ul><ul><li>has like Earth ! Mars's equator is 4,213 miles </li></ul><ul><li>,and 228 million kilometers from the sun. It takes 24.6 </li></ul><ul><li>hours to spin on its axis, and it takes 1.88 years to </li></ul><ul><li>orbit the sun. Mars got two moons. </li></ul>
  8. 8. Jupiter <ul><li>Jupiter is the largest planet </li></ul><ul><li>in our Solar System. The </li></ul><ul><li>planet has winds that goes </li></ul><ul><li>to 400 kilometers per hour! </li></ul><ul><li>It has amazing clouds, which </li></ul><ul><li>are made of frozen water </li></ul><ul><li>crystals, its atmosphere is </li></ul><ul><li>made of helium, and </li></ul><ul><li>hydrogen. If you compare </li></ul><ul><li>Earth with Jupiter, Jupiter </li></ul><ul><li>would be 11 times bigger! </li></ul><ul><li>Jupiter’s gravity is very strong </li></ul><ul><li>because of it’s humongous mass. It has </li></ul><ul><li>a thin unclear ring around it, and made of </li></ul><ul><li>fine dust! Jupiter’s equator is 88.650 miles, </li></ul><ul><li>482 million miles from the sun, It takes </li></ul><ul><li>9.9 hours to spin on its axis, and it takes </li></ul><ul><li>11.8 years to have a full orbit around the sun. </li></ul><ul><li>Jupiter has 28 moons! </li></ul>
  9. 9. Saturn <ul><li>Saturn is second largest planet in the Solar </li></ul><ul><li>System. It consists of liquid and gas. Saturn </li></ul><ul><li>has fierce winds that </li></ul><ul><li>goes 992 miles per hour. </li></ul><ul><li>Saturn has extraordinary </li></ul><ul><li>rings they consist of rock, </li></ul><ul><li>frozen water, and dust altogether. </li></ul><ul><li>About every 5 years the position of </li></ul><ul><li>Saturn changes, it goes up then down. </li></ul><ul><li>Its equator is 80,389 miles, 885 million miles </li></ul><ul><li>from the sun, 10.5 hours to spin on its axis, </li></ul><ul><li>It takes 24.46 years to orbit around the sun </li></ul><ul><li>, and it has at least 33 moons attached to it. </li></ul>
  10. 10. Uranus <ul><li>Uranus as you can </li></ul><ul><li>see its rings are </li></ul><ul><li>upside down, but its </li></ul><ul><li>Not only the rings, </li></ul><ul><li>so as Uranus! </li></ul><ul><li>Hypotheses were </li></ul><ul><li>made that the planet </li></ul><ul><li>could have had a </li></ul><ul><li>collision in the period of </li></ul><ul><li>The planets’ formation. Uranus’s rings are </li></ul><ul><li>very dark, and consists of boulders. </li></ul><ul><li>Uranus’s atmosphere is </li></ul><ul><li>made of hydrogen, and helium. </li></ul><ul><li>Uranus’s equator is 31,693 miles, </li></ul><ul><li>1.8 billion miles from the sun, 17.2 hours </li></ul><ul><li>To spin on its axis, it takes 84.01 years </li></ul><ul><li>To orbit the sun, and it has 21 moons. </li></ul>
  11. 11. Neptune <ul><li>Neptune is very similar </li></ul><ul><li>to Uranus, its also the </li></ul><ul><li>most distant planet </li></ul><ul><li>from the sun. Neptune’s </li></ul><ul><li>rings are narrow, and </li></ul><ul><li>dark. The clouds in there </li></ul><ul><li>are constantly changing. </li></ul><ul><li>Neptune, and Uranus both </li></ul><ul><li>colored blue because of the </li></ul><ul><li>non smelling gas called methane </li></ul><ul><li>Neptune’s equator is 30,710,2.8 </li></ul><ul><li>billion miles from the sun it takes 16.1 </li></ul><ul><li>hours to spin on its axis, and 165.8 years </li></ul><ul><li>To orbit around the sun. It got 8 moons. </li></ul>
  12. 12. Terrestrial Planets <ul><li>The terrestrial planets </li></ul><ul><li>are as shown in the </li></ul><ul><li>diagram; Mercury, </li></ul><ul><li>Venus, Earth, and </li></ul><ul><li>Mars. You can as well </li></ul><ul><li>say they are rocky </li></ul><ul><li>planets. They all have </li></ul><ul><li>rocky surfaces, and </li></ul><ul><li>most of them are similar </li></ul><ul><li>to each other in many ways. </li></ul><ul><li>Venus has volcanoes like Earth, and </li></ul><ul><li>Mars, which is not active in Mars. </li></ul><ul><li>Earth has craters like Mercury, and other </li></ul><ul><li>many other similarities they share. </li></ul>
  13. 13. Jovian Planets <ul><li>Jovian planets are </li></ul><ul><li>also known as the Gas </li></ul><ul><li>Giants. They are; </li></ul><ul><li>Saturn, Jupiter, </li></ul><ul><li>Neptune, and </li></ul><ul><li>Uranus. These are </li></ul><ul><li>the largest planets </li></ul><ul><li>in the solar system. Like </li></ul><ul><li>The terrestrial planets all </li></ul><ul><li>of them have common </li></ul><ul><li>things. They all have rings. </li></ul><ul><li>Neptune, and Uranus are like twins </li></ul><ul><li>for all the similarities they have in </li></ul><ul><li>common. Jupiter and Saturn share about </li></ul><ul><li>The same size in the equator. </li></ul>
  14. 14. Pluto is not a Planet!!! <ul><li>I am sure you have </li></ul><ul><li>been wandering </li></ul><ul><li>why I did not </li></ul><ul><li>mention Pluto, when </li></ul><ul><li>I described each </li></ul><ul><li>planet. I did that </li></ul><ul><li>because Pluto is no </li></ul><ul><li>longer a planet! That </li></ul><ul><li>decision was made in </li></ul><ul><li>the summer of 2006, </li></ul><ul><li>when all astronomers </li></ul><ul><li>gathered, and made a new </li></ul><ul><li>definition for the word “planet” </li></ul><ul><li>which is that a planet must go </li></ul><ul><li>around the planets in a circler orbit. </li></ul><ul><li>Unfortunately, Pluto didn’t have one </li></ul><ul><li>instead it had an elliptical orbit. That </li></ul><ul><li>demoted Pluto from being a planet! </li></ul>
  15. 15. Rings Formation on planets <ul><li>The cause of rings becoming formed </li></ul><ul><li>is still confusing. Hypotheses said that it happens if a moon or any size that is similar comes too near to a Planet its gravity’s strength tears it into lots of pieces then it keeps orbiting its planets. Earth cannot have rings, because even if it had the moon would tear it apart first. That was what astronomers think that this might be the way the rings were formed. </li></ul>
