Meteoroids
A meteoroid is a small particle from a comet or asteroid that is in orbit around the Sun. These particles range in size from small grains to boulders. When a meteoroid enters the Earth's atmosphere and vaporizes, it becomes a meteor, often referred to as a shooting star.
Characteristics of Meteoroids
- Size: Meteoroids can be as small as a grain of sand or as large as a boulder.
- Composition: They are composed of various materials, including rock, metal, and ice.
- Origin: Meteoroids come from comets or asteroids in the solar system.
- Speed: They travel at high speeds when entering the Earth's atmosphere, causing them to heat up and produce a bright trail of light.
Study Guide
Here are some key points to focus on when studying meteoroids:
- Describe the characteristics of meteoroids, including their size, composition, and origin.
- Explain the difference between a meteoroid, meteor, and meteorite.
- Discuss the process of how a meteoroid becomes a meteor when entering the Earth's atmosphere.
- Explore the potential impacts of larger meteoroids on Earth and how scientists track and study them.
- Compare and contrast meteoroids with other celestial bodies, such as asteroids and comets.
Understanding meteoroids is an important aspect of studying the solar system and the potential hazards they may pose to Earth.
