Exhibition Text

The Sun, an unremarkable star, holds in orbit a system of planets.  If most Sun-like stars have planets, then there should be billions of planets in our Milky Way Galaxy. Numerous other planetary systems have already been detected, many with configurations quite different than that of our solar system.
