Asteroid Apophis 99942

  1. 2. What is an Asteroid? <ul><li>Large rocky or Metal bodies </li></ul><ul><li>relatively warm inner solar </li></ul><ul><li>system </li></ul>
  2. 3. Why chose this topic?
  3. 4. Apophis 99942
  4. 5. <ul><li>History...? </li></ul><ul><li>A ncient spirit of evil and destruction.. </li></ul><ul><li> Demon.. </li></ul>
  5. 6. <ul><li>The impact would 100,000 times more powerful than the nuclear bomb dropped on Hiroshima </li></ul><ul><li>broke the record for the highest level on the Torino Scale, </li></ul><ul><li>diameter is approximately 390 meters (1280 ft). </li></ul>What is Apophis 99942?
  6. 7. Apophis 99942 <ul><li>f irst discovered by.. </li></ul><ul><li>- Roy A. Tucker, David J. Tholen and Fabrizio Bernardi and the Kitt Peak National Observatory on </li></ul><ul><li>June 19,2004. </li></ul><ul><li>At first.. </li></ul><ul><li>-received the provisional designation “2004 MN4” </li></ul><ul><li>On June 24,2005.. </li></ul><ul><li>- received the permanent number 99942 </li></ul>
  7. 8. <ul><li>Actual photo of Apophis 99946 </li></ul>Predicted date: April 13 2036
  8. 9. <ul><li>There are ways to change the track of the asteroid: </li></ul><ul><li>Bump it: a 1-ton Kinetic energy impact </li></ul><ul><li>Thrust it: a ION-Drive rocket engine builds thrust over few weeks on the asteroid </li></ul><ul><li>Tug it: Gravity Tractor </li></ul><ul><li>Nuke it: Nuclear Explosion just above the surface </li></ul>
  9. 10. Kinetic Energy impact <ul><li>- A device that will deflect objects like asteroids and comets by hitting them with a high-speed spacecraft.. As the material blows away from the object, preventing an impact. Kinetic energy equals the speed of impact squared times mass. </li></ul>
  10. 11. ION Thrust <ul><li>- The ion propulsion system will provide the spacecraft with the thrust that it will require to reach its target asteroids. Ion propulsion was proved on NASA's Deep Space 1 mission, which tested it and 11 other technologies while journeying to an asteroid and a comet.   </li></ul>
  11. 12. Gravity Tractor <ul><li>- A  gravity tractor  (GT) is a spacecraft that deflects another object in space, using only its gravitational field to transmit the required impulse. </li></ul>
  12. 13. Nuclear Explosion <ul><li>- Nuclear explosion plan is the gravity tractor attaching to an asteroid and firing the craft's engines to push the space rock away using the nuclear missile. </li></ul>
  13. 14. More Ways to stop this collision <ul><li>Solar Sail </li></ul><ul><li>- the solar energy from the sun can actually apply pressure on an object. </li></ul><ul><li>Robert Munch on it. </li></ul><ul><li>- Rocketing packs of ravenous robots out to an asteroid. </li></ul>
