  1. Comets and Asteroid By: Jowb Borja and AlyannaSharyce D. Aparilla

  3. What are Asteroids? • rocky-metallic • to small to be planets • Planetoids (minorplanets) • leftover material • Solar System • Asteroid Belt • dangerous

  4. Types of Asteroids (primary) C-TYPE M-TYPE S-TYPE

  5. C-TYPE • Carbonaceous • Common variety • 75% of known asteroids • Much darker en.wikipedia.org

  6. M-TYPE • Moderately bright • Made of nickel-iron • Third most common abyss.uoregon.edu

  7. S-TYPE • Second most common • Moderately bright • Consists of iron-magnesium • Dominant • Inner asteroid belt http://en.wikipedia.org

  8. HOW ARE ASTEROIDS FORMED? • leftovers • formation of solar system • birth of Jupiter • Prevented planetary bodies • from forming • gap between Mars and Jupiter • Causing small objects • collide with each other • fragment into the asteroids seen today.

  9. What Are Comets ? • snowy dirtballs • Inhabit the Oort cloud, • Kuiper Belt • Asteroid Belt

  10. Physical characteristics • Solid nucleus consist • -ice (frozen water) • - dust coated with dark organic material • - ammonia • - carbon dioxide • - carbon monoxide • - methane • Coma • Dust tail • Ion tail

  11. Formation • material left over from formation of planets • solar wind pushed remains into the outer • region • remained to form lumps of frozen gas and dust. • temperature :cold enough

  12. Orbital Characteristics • Elliptical Orbit • Perihelion • Kepler’s Law • Main Belt comets • Short Period comets (periodic comets) • Long Period comets • Single apparition comets • Sun grazers

  13. Main Belt comets Comets in the Asteroid belt

  14. Short period comets (Periodic Comets) • 1 orbit takes 200 yrs or less • originate from kuiper’s belt • active comets dragged by the gravitational • interactions with inner planets

  15. Long Period comets • 1 orbit takes 200 yrs or more • originate from Oort cloud • get slung inward by gravitational pull of passing • stars

  16. Single apparition comets Comets that are not bound to the sun

  17. Sun grazers Comets that smash into the sun

  18. Naming Named after their discoverer

  19. History • Thought to be traveling the earths atmospere • 1577 astronomer Tycho Brahe revealed that comets travels far beyond the moon • Isaac newton • a. comets orbit around the sun • b. predicted it will return again and again
