In this video we will begin to look at some of the key features that describe the parts our Solar System.

Quite simply it is the name given to the collection of planets and other bodies that orbit a star.

It is only recently by using satellites, such as Kepler, that we now know that our own solar system is not unique and indeed they may be common around many other stars.

Our Solar System consists of a central star, our Sun, and 8 orbiting planets

Beyond the orbit of Mars there is the asteroid belt.

This is about 150 million kilometres wide and consists of irregular bodies that orbit the Sun which are made from rock and ice varying in size from dust grains up to one so large, 945 kilometres across, it has a name : Ceres.

It is thought that the asteroid belt is parts of a planet that failed to form because of the gravitational influence of nearby Jupiter.

The warmest planet, if you checked, is Venus and not Mercury. Although it is much further away from the Sun than Mercury, it has an atmosphere very rich in carbon dioxide which has resulted in a very effective greenhouse effect.

Few probes sent to the surface of Venus have survived for more than a few hours in the hot and corrosive atmosphere.

The Earth exists in what we call the Goldilocks zone. We are neither too near to the Sun nor too far away to prevent water being a liquid.

Although we have now discovered many distant solar systems, very few have planets in their equivalent Goldilocks zone, so we are unsure if life maybe common, rare or non existent around other stars.
