Check out this uber cool graphic of the size of exoplanet candidates (planets to be confirmed beyond our solar system) from NASA's Kepler mission
We live in a time when we know of thousands of planets beyond our solar system that are orbiting other stars - think about that.....
It is quite clear that planets are a natural byproduct of stellar formation and our Milky Way probably contains BILLIONS if not TRILLIONS of planets.
Oh, and each of the 200 billion plus galaxies we can see should also have planets as well.
What a Universe!
