All About The Oort cloud


The Sun and the planets are at the center of the Oort Cloud.

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 mostly composed of water, ice, ammonia and methane.

Objects in the Oort Cloud are also called Trans-Neptunian objects.

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 Jan Oort, who discovered the cloud in 1950.

Not all comets come from the Oort Cloud, some also come from the Kuiper Belt.

On Earth we can only see comets when they leave the Oort Cloud.

The region of space between comets and stars is called interstellar space. It is so dark we cannot see it.

It would take about 30,000 years for the space probe Voyager 1 to travel to the far side of the Oort Cloud, such is it’s vast size.

The Oort Cloud is approximately 30 trillion kilometers from the Sun.

All of the objects in the Oort Cloud and the Kuiper Belt are believed to be the left-overs from the birth of the Solar System about 4.6 billion years ago.

The comets in the Oort Cloud orbit the Sun in every direction.

The Oort Cloud is also known as Opik-Oort.

Our best know comet, Halley’s Comet, is believed to have originated in the Oort Cloud. It is now a Kuiper Belt object.

The Oort Cloud is taught to be the built up of two regions, a spherical Oort Cloud on the outer region, and a disc shaped inner cloud, called the Hills Cloud.

Astronomers and scientists widely believe of the Oort’s Cloud existence, but we are yet to have a sighting of it.
