"All 786 known planets (as of June 2012) to scale (some planet sizes estimated based on mass). This [small box] is our solar system. The rest of these orbit other stars and were only discovered recently. Most of them are huge because those are the kind we learned to detect first, but now we’re finding that small ones are actually more common. We know nothing about what’s on any of them. With better telescopes, that would change. This is an exciting time.”
