This downloadable resource is an activity to determine the distance to the Sun.

In this activity, students use an image of the Sun to determine its distance from the Earth using mathematics.

The ratio of distance to the width of the image is used to obtain an experimental value for the distance to the Sun, which students can compare to the known value.

This activity introduces the idea of sources of error and allows students to make a percentage error calculation based on their result.
