Between Mars and Jupiter lies the asteroid belt, home to rocky asteroids that orbit the sun. Comets are balls of ice and rocks that develop long tails as they near the sun due to warming and gas release. Meteoroids are small objects that orbit the sun and occasionally collide with celestial bodies like the moon, and meteors are meteoroids that burn up in a planet's atmosphere in a bright streak. Those that reach a planet's surface are called meteorites.

Asteroids ,comets and meteors
- 1. Asteroids • Between the orbits of Mars and Jupiter are asteroids, rocky or metallic objects that orbit the Sun. • Most asteroids are located in the asteroid belt . • Some asteroids travel as far from the Sun as Saturn’s orbit . • Other asteroids have orbits that cross earth’s path .
- 2. Comets • It is a ball of ice and rocks that orbits the Sun. • As a comet approaches the sun ,the sunlight warms the comet ice causing the ice to turn to gas forming a cloud of gases. • Near the sun the radiations pushes the cloud away forming comet tail which is always pointing away from the Sun .
- 3. Meteoroids • They are small rocky or metallic objects that orbits the Sun. • The craters on the moon where formed by meteoroids collisions
- 4. Meteor • It is a meteoroid that enters Earth’s atmosphere, it appears as a bright streak in the sky .
- 5. Meteorite •If a meteor fails to break apart and burn up in the atmosphere it can hit Earth’s surface . •A meteoroids that strikes Earth’s surface is a meteorites
