Can’t we just look at it?
In episode 56 and episode 57, we looked at a couple of methods of detecting planets that are orbiting around stars other than our own sun. These methods involve a good deal of analysis and inference.

Since this is the last episode on finding exoplanets, here are a couple of links to pages about finding them, should you desire to dig a bit deeper.
