Space in a Snap: Where does the solar system end? The Oort Cloud.

The solar system we call home has our sun, eight planets, all their moons, the asteroid belt, and lots of comets. Outside Neptune’s orbit is the Kuiper Belt. An almost empty ring around the sun that has icy bodies, almost all smaller than Pluto, making slow orbits around the sun. But what’s beyond the Kuiper belt? Beyond the fringes of the Kuiper belt is the Oort Cloud.
