Some students assume that the distances between planets in the solar system are much smaller than they are

Earth and Space

Misconception RESEARCH REVIEW

This may be because of the misrepresentation of the distances between the celestial bodies in diagrams. 

Diagnostic Resources

The following worksheets may help to identify whether students hold this particular misconception.

  • Movements in the solar system (5-11)

    This activity is a summary of what is known about the solar system.

  • Building a model of the solar system with fruit (11-14)

    Here you construct a model of the solar system to show the relative size of the planets, the distance of each planet from the Sun and the spacing between the planets.

    It shows clearly why the sizes and distances are often drawn with different scales.

  • Planets in the Copernican system (11-16)

    Copernicus not only offered an alternative model that looked simpler than the heliocentric model. He also extracted new information from his heliocentric scheme: the order and relative sizes of the planetary orbits.

    Estimating the size of the planets themselves would have to wait until telescopes had been invented. A rough model of the solar system known to Copernicus would require the items listed.
