Practical exercise 4: What are the planets’ sizes?


• models of the Sun and planets (see section a), calculator, charts, chalk


1. You can use the practical exercise from section b) in this section as well.

2. Take the model of Jupiter as the basis.

• Calculate how big would be the models of other planets and the Sun.

• Try to compare what spherical objects would have the size which you have calculated; what would be the correct models instead of table tennis balls?

• Now calculate what would be the distances of individual planets from the Sun in this model.
