Exploring Comets, Meteoroids, Asteroids, and the Oort Cloud in Our Solar System

Discover the fascinating world of comets, meteoroids, and asteroids, the other objects in our solar system. Comets are composed of dust, rock, and frozen gases, originating from the mysterious Oort Cloud. Learn about the spectacular Hale-Bopp comet and its structure when it approaches the sun. Dive into the nature of meteoroids, meteors, and meteorites, and how they interact with Earth’s atmosphere. Explore the Asteroid Belt, its formation, and the sizes of asteroids that range from tiny fragments to massive bodies.

  1. Chapter 12Other Objects in the Solar System Pgs. 356 - 359

  2. Comets • Made of dust and rock particles, mixed with frozen water, methane, ammonia • Oort cloud – billions of comets that surround the solar system • Hale-Bopp – seen from earth, larger than most that came close to the sun • Structure – when close to the sun vaporizes and releases dust and jets of gas

  3. Meteoroids • Pieces of a comet’s nucleus, dust and rock

  4. Meteor • A meteoroid that burns up in Earth’s atmosphere

  5. Meteorite • When a meteoroid does not burn up completely in the atmosphere and strikes Earth

  6. Asteroid • Piece of rock similar to the materials planets were formed from • Asteroid Belt – between Mars and Jupiter, due to Jupiter’s gravity • Size – range from tiny to 940 km • Formed early in the history of the solar system

  7. Questions • What is a comet? • Draw the structure of a comet. • What is a meteorite? • What is a meteor? • What is a meteorite? • Where can asteroids be found? • What is an Oort Cloud?
