1.1. The Sun, planets and asteroids
• the Sun (a star) is at the center of our Solar System
• there are eight planets and the asteroid belt (Mercury, Venus, Earth, Mars, Asteroid
belt, Jupiter, Saturn, Uranus, and Neptune) in orbit around the Sun
• each planet has its own
features, size, orbit and position in relation to the Sun, composition (rocky and gas
planets) and number of moons (some have no moons)
• the planets and Asteroids take different amounts of time to revolve around the Sun*
1.2. Moons
• moons, including our Moon do not give out their own heat and light
• our Moon can be seen from Earth because the light from the Sun shines onto its
surface
• on the Moon we can see craters, lighter areas which are mountains, and darker areas
which are flat plains
KEY QUESTIONS
• How can we tell the difference between a
star and a planet? • What are asteroids? •
What is a moon? Does the Moon produce its
own light? • Can we see the Moon during
the day?

1. The solar system.
The solar system consists of the Sun and all the planets that orbit around it. It also
includes asteroids and the planets' moons. In the first image, you can see a diagram of
the solar system. In the second image in the next activity, you can see another diagram
of the solar system. Both these diagrams try to show you what the solar system is like.
The solar system was formed billions of years ago.
