Build a better telescope and what do you see? Worlds. Lots of worlds circling suns far from our own solar system. - Thus far, we have peeped four hundred and sixty six worlds circling suns other than our own Sol. That is the number as of July 29, 2010. This said number continues to climb. - Small rocky worlds like Earth are known to exist. Their presence effect their suns and gas giants in their solar systems. What we can guess, judging from our own solar system, is that the galaxy is lousy with tiny moons. Said moons often have interesting features such as Europa and Titan. Unfortunately, moons are too small to be seen in a star system a few light years away.
