  2. Unit 9 Lesson 11: Asteroids, Comets, and Meteoriods • Agenda: • Explain the interaction of the sun and comets in the solar system. • Describe other objects in the solar system, such as asteroids, comets, and meteoroids

  3. What is an asteroid? • It is an irregularly formed rock piece that has craters from collisions. They could have been formed by collisions or are pieces that didn’t form into planets due to Jupiter being nearby. • Between 1 – 480 miles in diameter

  4. Ceres • Largest found asteroid • Originally classified as a planet • ONLY dwarf planet within inner planets!!!

  5. Gaspra • Found in the inner section of the asteroid belt • Some craters and flat areas Ida • Found in the inner section of the asteroid belt • One of the most cratered surfaces • Has a moon (Dactyl)

  6. What is a comet? A comet is a body that orbits the sun, consisting of a mass of ice, gas, and dust with a tail that streams away from the sun. A comet has 3 parts: Nucleus: made up of ice, rock and dust Coma: a cloud of dust and gas that surrounds the nucleus Tail: created by gas from the solar energy melting the ice in the nucleus

  7. Halley’s Comet • Seen every 75 – 76 years • Recorded as being seen as early as 240 B.C. • Last seen in 1986 • When should it be seen again???? • Shoemaker-Levy’s Comet • Fragments crashed into Jupiter in 1994 • Hale-Bopp Comet • Discovered in 1995 by American observers • How are celestial objects named?? • Previously named after discoverers or mythology • Now numbers, position in the sky, and date of discovery are used • Example: Hale-Bopp Comet = C/1995 O1

  8. Meteor vs. Meteoroid vs. Meteorite A meteoroid is any small body, usually leftover from comets, traveling through space. A meteor is a meteoroid that has entered earth´s atmosphere A meteorite is a meteor that is big enough that it doesn’t burn up Earth’s atmosphere. A crater is formed by a meteorite impacting the earth’s surface.
