Distances

13.12 - Be able to determine astronomical distances using heliocentric parallax

13.16 - Understand how Cepheid variables can be used to determine distances

13.13 - Understand how to use a Hertzsprung-Russell diagram to determine distances to stars

We will look at three ways to determine distances to stars:

  • Heliocentric Parallax
  • Cepheid Variables
  • Using the HR Diagram
