The Oort Cloud surrounds our Solar System.
The Oort Cloud contains billions and billions of frozen comet-like bodies that form a gigantic ball shaped place that surrounds our Solar System.
Objects in the Oort Cloud are also called Trans-Neptunian objects.
Objects in the Oort Cloud are mostly composed of water, ice, ammonia and methane.
The Oort Cloud lies beyond the Kuiper Belt.
The Oort Cloud stretches way beyond Pluto.
The comets within the Oort Cloud travel on vast orbits around the Sun.
From the edge of the Oort Cloud the Sun looks like a bright star.
The Oort Cloud is about 5 times the size of Earth.
The Oort cloud was named after astronomer Jaan Oort, who discovered the cloud in 1950.
