Solar system

  1. 1. THE SOLAR SYSTEM <ul><li>The sun,eight planets,satellites,some celestial bodies such as asteroids and meteoroids form the solar system </li></ul>
  3. 3. SUN The sun is in the centre of the solar system it is huge and made up of extremely hot gases. It provides the pulling force that binds the solar system.The sun is the ultimate source of heat and light of solar system.The sun is about 150 million km away from the earth.
  4. 4. MERCURY <ul><li>Orbit </li></ul><ul><li>Closest to sun </li></ul><ul><li>Appears to travel fastest </li></ul>One orbit around sun- 88 days One spin on axis- 59 days One orbit around sun- 88 days One spin on axis- 59 days
  5. 5. VENUS <ul><li>2nd from Sun </li></ul><ul><li>6th largest </li></ul><ul><li>brightest </li></ul><ul><li>One orbit around sun 255 days </li></ul><ul><li>One spin on axis 243 days </li></ul>
  6. 6. EARTH <ul><li>3rd from the Sun </li></ul><ul><li>Moon is 1/6 mass of earth </li></ul><ul><li>period of rotation: 24 hours </li></ul><ul><li>period of orbit 365.25 days </li></ul><ul><li>It is known as a unique planet </li></ul>
  7. 7. MARS <ul><li>Mars is the 4th Planet from the Sun </li></ul><ul><li>Solid carbon dioxide is found at the poles </li></ul><ul><li>Mars is known as the Red Planet </li></ul><ul><li>One orbit around sun 687 days </li></ul><ul><li>One spin on axis one day </li></ul>
  8. 8. one orbit around sun- 11 years,11 months. one spin on axis 9 hours 56 mints . JUPITER <ul><li>Unlike the inner planets, Jupiter is not a solid body, but instead is a ball of gas and liquid (mostly hydrogen and helium). </li></ul>
  9. 9. SATURN <ul><ul><li>One orbit around sun 29 years 5 months. </li></ul></ul><ul><ul><li>One spin on axis 10 hours 40 mints </li></ul></ul>SATURN <ul><li>Saturn : </li></ul><ul><li>Saturn is a gas giant. </li></ul><ul><li>It has strong surface winds (500 m/sec). </li></ul><ul><li>Saturn is less dense than water. </li></ul>
  10. 10. URANUS <ul><li>One orbit around sun -84 years. </li></ul><ul><li>One spin around axis 17 hours 14 mints. </li></ul>
  11. 11. NEPTUNE <ul><li>The blue coloration of Neptune is probably due to the presence of methane </li></ul>Note the apparent storms                   One orbit around sun 164 years One spin around axis 16 hours 7 mints
  12. 12. SATELLITE <ul><li>Satellite is a celestial body that moves around the earth. </li></ul>
  13. 13. THE MOON <ul><li>Our earth has only one satellite. That is the moon. </li></ul><ul><li>It appears so big because it is nearer to our planet than other celestial bodies. </li></ul><ul><li>The moon moves around the earth in about 27 days. </li></ul><ul><li>The moon does not have conditions favorable for life. It has neither water nor air. </li></ul>
  14. 14. CELESTIAL BODIES <ul><li>Asteroids- The tiny bodies which also move </li></ul><ul><li>around the sun are called asteroids. They are found between the orbits of Mars and Jupiter. </li></ul><ul><li>Meteoroids- The small pieces of rocks which move around the sun are called meteoroids. </li></ul>
