6. Asteroids Asteroids, Meteors and Comets
A rocky mass that orbits the sun
Range in size from nearly 600 miles across to dust particles
Most are found in the asteroid belt  between the orbits of Mars and Jupiter
A few pass close to the Earth or enter the atmosphere as meteors.

7. Asteroids Asteroids, Meteors and Comets
There are millions of asteroids in the solar system but most have not been identified.
They may be the remains of the formation of the solar system.
The largest asteroid on record is Ceres, which is large enough to be considered a dwarf planet.

8. Asteroids, Meteors and Comets
Meteoroid A general term for a small particle from a comet or asteroid orbiting the Sun.

9. Meteor Asteroids, Meteors and Comets
A meteor is a meteoroid that burns and vaporizes upon entry into the Earth's atmosphere, commonly called a shooting star.
The light emitted is created by friction between the meteoroid and the atmosphere.

10. Asteroids, Meteors and Comets
Meteorite A meteoroid that survives its passage through the Earth's atmosphere and lands on the Earth's surface

11. Crater Asteroids, Meteors and Comets
A bowl-shaped depression with a raised rim, formed by the impact of a meteoroid.

12. Comets Asteroids, Meteors and Comets
A celestial object made of ice and dust that orbits the Sun.
Because they can rarely be seen with the naked eye and many have large orbits, you will be lucky to see one in your lifetime.

13. Comets Asteroids, Meteors and Comets Oort Cloud
Longer period comets originate here in a region of the solar system far beyond the orbit of the dwarf planet, Pluto.
Here, billions of comets move in nearly circular orbits around the Sun rather than in the elliptical plane of our planets.

14. Comets Asteroids, Meteors and Comets Kuiper Belt
Another belt in the Solar System (besides the Asteroid Belt) that lies out past the orbit of Pluto.
Shorter period comets originate here
This belt has millions of icy comets which circle the Sun in the same plane as our planets.

15. Comets Asteroids, Meteors and Comets Has three components:
Nucleus – (called a dirty snowball) frozen ice, gas and dust
Coma - water vapor and other gases
Tail - made of gas (ions) and dust

16. Comets Asteroids, Meteors and Comets
Every once in a while, comets are disturbed by a passing star or collision with other comets and some fall in toward the solar system.
Because their orbits are so large some comets will only pass near the Sun once. 
When a comet nears the sun, the “tail” always points away from the sun due to the solar winds.
