Sub-index for this section on astronomy - as well as planet Earth, what else is there out in space? and how do we find out?

1. History of Solar System models

2. Our contemporary model of our Solar System, planet data, and beyond

3. Methods of astronomical observation - types of telescope and what thy can observe

4. Details, definitions and explanations of the different objects in our Solar System!

5. Physics of circular motion, forces involved in solar and planetary systems
