While the planets of our solar system orbit in a flat plane, the Oort Cloud is believed to be a giant spherical shell surrounding the Sun, planets and Kuiper Belt Objects. It's like a big, thick bubble around our solar system, made of icy, comet-like objects.
The Oort Cloud's icy bodies can be as large as mountains — and sometimes larger. In the silence and darkness between the stars, where our Sun appears as just a particularly bright star, a theorized group of icy objects collectively called the Oort Cloud coast along their orbits like lazy moths around a porch light.
Scale and Distance. The Oort Cloud is the most distant region in our solar system, and it's jaw-droppingly far away,extending perhaps one-quarter to halfway from our Sun to the next star. The inner edge of the Oort Cloud, however, is thought to be located between 2, and 5, AU from the Sun, with the outer edge being located somewhere between 10, and , AU from the Sun.
If those distances are difficult to visualize, you can instead use time as your ruler. Even if you could travel at the speed of light about million miles per hour, or 1 billion kilometers per hour , a trip to the Oort Cloud would require that you pack for a lengthy expedition.

Sometimes those debris are jostled out of the cloud and fall toward the Sun, becoming comets.
It can take thousands of years for an Oort Cloud comet to go around the Sun. More Resources. Oort Cloud. The Latest. Oort Cloud Illustration. Oort Cloud Comet Siding Spring. The path through the solar system is a rocky road. Asteroids, comets, Kuiper Belt Objects—all kinds of small bodies of rock, metal and ice are in constant motion as they orbit the Sun. Why do these miniature worlds fascinate space explorers so much? A new dwarf planet-like body has been found on the outer edges of the Solar System.
This object, called VP , is about km wide and is the second body of its class found since the identification of the dwarf planet Sedna in , and it joins an exclusive club composed of some of the strangest objects in the Solar System.
The observable Solar System can be divided into three regions: the rocky terrestrial planets and asteroids of the inner Solar System, the gas giant planets, and the icy Kuiper Belt objects, which include Pluto.
Sedna and VP are strange objects because they reside in a region where there should be nothing, according to our theories of the Solar System formation. Their orbit is well beyond that of Neptune, the last recognized planet of the Solar System, and even beyond that of Pluto, which differs from planets because of its size, unusual orbit, and composition.
Pluto, once considered a planet, is now considered the lead object of a group of bodies called plutinos.THE OORT CLOUD By: Austin Fitter Structure & Composition Surprisingly enough the Oort Cloud is believed to be created from the same elements as the original protoplanetary disc that formed the sun. Also it was estimated to be billion years ago that the Oort Cloud was created.
