NSO Investigation - Comparing Planets

Comparing Planets

Planets are found a very long way from the Earth and a powerful telescope is required to make accurate measurements.

To get some idea of the distances involved look in the NSO Astronomy Section at the planet links in the Solar System page.

You can find out facts and figures relating to all the planets.

Stages of the investigation

• The investigation is broken down into four stages.

• Carry out each stage one in turn, beginning with the planning stage.

• Information in support of your work is available as you proceed.
