Measuring the Distance to Stars

It is the goal of astronomers to determine where we are in space, and where everything else that we see is located relative to us. To know where stars are, astronomers utilize various measuring techniques that will be discussed over the following pages. By learning where stars and galaxies are, astronomers can then determine what is happening to them, how these stars and galaxies are moving, and perhaps even understand what the potential origin and fate of the entire Universe may be.

This section is divided into the following parts:


Spectroscopic Parallax:

Cepheid Variables:

Type Ia Supernovae:

Hubble Law:


You can take a break and return to Introduction to the Stars, or to the Spectral Classes of Stars. Or you can move forward to a discussion on Parallax. Just do not go back to the Syllabus as a time like this.
