Detecting Exoplanets

The detection and discovery of planets around other stars has only become possible in my lifetime. There are two primary methods used to discover exoplanets - the Doppler Method and the Transit Method.
Watch this video Introduction to the Doppler Method of detecting exoplanets (also known as the “Radial Velocity Method.”)
Then watch this video for an Introduction to the Transit Method of discovering exoplanets.
Read 21.4 Planets beyond the Solar System: Search and Discovery for an overview of observational techniques used to detect exoplanets, including direct and indirect methods such as the Doppler and transit techniques.
