2. WHAT IS IT?
It is our Sun and everything that travels around it. Our solar system is in the Milky Way Galaxy. The Milky Way is an spiral Galaxy. Earth is located on one arm of the spiral.

3. STARS, GALAXIES AND PLANETS
A planet is an object orbiting a star that is large enough to be rounded by its own gravity.
There are eight planets in the Solar System.

4. THE MILKY WAY
We live in one of the arms of a large spiral galaxy called the Milky Way. The Sun and its planets (including Earth) lie in this quiet part of the galaxy, about half way out from the centre.

5. ASTEROIDS AND THE ASTEROID BELT
Asteroid: Are small solar system bodies that orbit the Sun. Made of rock and metal, they also contain organic compounds. Asteroids are similar to comets but do not have a visible coma (fuzzy outline and tail) like comets.
Asteroid Belt: The asteroid belt lies between the orbits of Mars and Jupiter in the Solar System. It is a group of asteroids.
