- 2. LEARNING COMPETENCY • Compareand contrast comets, meteors, and asteroids.
- 3. IMPORTANCE • It isimportant to compare and contrast comets, meteors, and asteroids in order to identify and understand these celestial objects in the outer space.
- 4. Celestial Objects • Celestial Objectsare sometimes referred to as Near-Earth Objects.
- 5. Celestial Objects • CelestialObjects are sometimes referred to as Near-Earth Objects. • COMETS, ASTEROIDS, and METEORS are examples.
- 6. LEARNING COMPETENCY • Compareand contrast comets, meteors, and asteroids.
- 7. Can you identifythese celestial objects? COMET ASTEROID METEOR

- 10. COMET • COMET ismade up mostly of ice mixed with dusts, and rocks. • Its main body, the NUCLEUS, contains frozen methane, ammonia, and water ice.
- 11. PARTS OF ACOMET
- 12. ORIGINS OF COMETS KuiperBelt and Oort Cloud
- 13. ORIGINS OF COMETS KuiperBelt and Oort Cloud
- 14. TAIL EFFECT • Whena comet is heated by the sun, its ice begins to sublimate. The mixture of ice crystals and dust blows away from the comet's nucleus in the solar wind, creating a pair of tails. DUST TAIL and PLASMA/GAS/ION TAIL
- 15. COMET'S ORBIT Elliptical Orbit Perihelion- closest point in a comet's orbit to the sun. Aphelion - farthest point in a comet's orbit to the sun.
- 16. FAMOUS COMETS Periodic Comet •Comet Halley (1986) Non-periodic Comet • Hale -Bopp (1995) • Hyakutake (1996) • McNaught (2006) • Lovejoy (2011)
- 17. FAMOUS COMETS Periodic Comet •Comet Halley (1986)
- 18. FAMOUS COMETS Non-periodic Comet •Hale -Bopp (1995)
- 19. FAMOUS COMETS Non-periodic Comet •Hyakutake (1996)
- 20. FAMOUS COMETS Non-periodic Comet •McNaught (2006)
- 21. FAMOUS COMETS Non-periodic Comet •Lovejoy (2011)
- 22. FAMOUS COMETS Comet Halley returnsto the inner solar system once every 76 years. Edmund Halley - British astronomer
- 23. Modeling Predict the appearanceof comets based on recorded data of previous appearance. COMET HALLEY YEAR First Recorded Appearance 1531 Predicted Year of the Next Appearance 1682 Predicted Year of the Next Appearance 1607 1758 1531 + 76 = 1682 + 76 =
- 24. Modeling The basis ofthe prediction is simply by adding 76 on the previously recorded year of apearance of the Comet Halley. It takes 76 years for the Comet Halley to orbit around the sun.
- 25. GUIDED PRACTICE INSTRUCTION: Predictthe appearance of comets based on recorded data of previous appearance. COMET HALLEY YEAR First Recorded Appearance 1531 Predicted Year of the Next Appearance 1682 Predicted Year of the Next Appearance 1835 Predicted Year of the Next Appearance
- 26. GUIDED PRACTICE What isthe basis of your prediction? How long it takes for the Comet Halley to orbit around the sun?
- 27. GUIDED PRACTICE INSTRUCTION: Predictthe appearance of comets based on recorded data of previous appearance. COMET HALLEY YEAR First Recorded Appearance 1531 Predicted Year of the Next Appearance 1682 Predicted Year of the Next Appearance 1835 Predicted Year of the Next Appearance 1531 + 76 = 1682 + 76 = 1607 1758 1682 + 76 = 1911
- 28. GUIDED PRACTICE The basisof the prediction is simply by adding 76 on the previously recorded year of apearance of the Comet Halley. It takes 76 years for the Comet Halley to orbit around the sun.
- 29. INDEPENDENT PRACTICE INSTRUCTION: Predictthe appearance of comets based on recorded data of previous appearance. COMET HALLEY YEAR First Recorded Appearance 1531 Predicted Year of the Next Appearance 1682 Predicted Year of the Next Appearance 1835 Predicted Year of the Next Appearance 1986 Predicted Year of the Next Appearance
- 30. INDEPENDENT PRACTICE What isthe basis of your prediction? How long it takes for the Comet Halley to orbit around the sun?
