Are made mainly of rocky particles and water ice. As they approach the sun, parts vaporize and form tails.

• Asteroids
• Comets
• Meteoroids

Are small, rocky objects that mostly lie in a belt located between the orbits of Mars and Jupiter. Is used to divide inner and outer planets

• Asteroids
• Comets
• Meteoroids

Form when asteroids collide and small pieces break off. If these pieces enter Earth’s atmosphere, they are called meteors. As they fall to Earth, they are called meteorites
