  • Students will use a mathematical formula to determine a celestial body’s unknown distance to the Sun.
  • Students will recognize the large distances between objects in our solar system.

Vocabulary

  • astronomical unit
  • celestial body
  • light intensity
  • inverse

About the Lesson

In this lesson, students will investigate relationships between light and distance and explore distances between objects in our solar system.

 As a result, students will:

  • Understand how to determine the distance of an object from the Sun by measuring the light intensity at the surface of the object.
  • Calculate an object’s location using the inverse square law.
