Asteroids, Comets, and Meteors

What is an Asteroid?

• A small rocky body orbiting the sun, mostly found in the asteroid belt between Mars and Jupiter.

• A large ball of gas that emits light and heat.

• A frozen mass of ice and dust that orbits the sun in a long, elliptical path.

• A natural satellite that orbits a planet.

What is a Dust tail (of a comet)?

What is the Kuiper belt?

• A region of the solar system beyond Neptune, containing many small icy bodies and dwarf planets.

What are Trojan asteroids?

• Asteroids that share an orbit with a larger planet, such as Jupiter, but do not collide with it because they gather around two special places in the orbit called Lagrange points.

• Asteroids that are found only in the asteroid belt between Mars and Jupiter.

• Asteroids that travel in highly elliptical orbits around the Sun.

• Asteroids that frequently collide with planets in the solar system.

Near-Earth objects (NEO) include all small ______ bodies that move near Earth.

• orbiting

• stationary

• burning

• falling
