Meteoroids
Definition
A meteoroid is a small rock or particle of debris in our solar system. They range in size from small grains to 1 meter-wide objects. Most meteoroids are fragments from comets or asteroids, while others are the result of collisions between asteroids.
Characteristics
- Size: Meteoroids can range in size from tiny dust particles to objects about 1 meter in diameter.
- Composition: They are composed of various materials including rock, iron, and nickel.
- Origin: Most meteoroids are remnants from the formation of the solar system, while others are fragments from comets or asteroids.
Formation and Origin
Meteoroids are formed through various processes such as the breakup of asteroids or comets, or as debris left over from the early solar system. They can be found throughout the solar system, with many of them orbiting the sun in the asteroid belt between Mars and Jupiter.
Study Guide
Here are some key points to focus on while studying meteoroids:
- What is a meteoroid and how does it differ from a meteor and a meteorite?
- Discuss the origin and composition of meteoroids.
- Explain how meteoroids are formed and where they are typically found in the solar system.
- Explore the potential impact of meteoroids on Earth and other celestial bodies.
- Research famous meteoroid impacts and their effects on Earth's geology and biology.
