Discuss the kinds of planetary systems we are finding around other starsīefore the discovery of exoplanets, most astronomers expected that other planetary systems would be much like our own-planets following roughly circular orbits, with the most massive planets several AU from their parent star.

Identify which kind of exoplanets appear to be the most common in the Galaxy.

Explain what we have learned from our discovery of exoplanets.
