No one knows. The Oort cloud is a hypothesised cloud of comets - it has not been directly observed.
It is believed to extend from about 2,000 AU to about 50,000 AU or the edge of the Solar System.

The Oort Cloud is believed to be?
a spherical cloud of cometary nuclei far beyond the Kuiper Belt
What size is the Oort cloud?
at least 3 a.u's to 5 a.u's distance across
Where is the Oort cloud located in space?
The Oort Cloud is a hypothetical sphere of comets left over from the birth of the solar system. It is named after the scientist who proposed its existence, and lies in a loose orbit far outside our Solar System. Although it has never been directly observed (because its constituents are too small and too far away for telescopes to detect) it is thought to be the source of the long period comets in the Solar System. Its existence can be inferred because the aphelia of long period comets tend be the same, suggesting they originated in some "reservoir" far outside our solar system. See the link for a very good description of the Oort Cloud and more info.
What are the ingredients of a cloud?
The condensing substance of cloud is typically water vapor, which forms small droplets or ice crystals, typically 0.01 mm in diameter. When surrounded by billions of other droplets or crystals they become visible as clouds.
What is a water droplet in a cloud that becomes rain when its diameter increases to how many times its original size?
100 times its original size. your welcome!
A spherical cloud of small icy fragments at the farthest reaches of the Sun's gravitational influence?
That is the Oort Cloud.That is the Oort Cloud.That is the Oort Cloud.That is the Oort Cloud.
What color is an Oort cloud?
the oort cloud is mostly black
What is the cloud that surrounds the solar system?
The Oort cloud.However, technically the Oort cloud IS part of our Solar System.See related link for more information.
Spherical region of comets surronding the solar system-what is it called?
The outer Oort cloud. (The inner Oort cloud is believed to be disk-shaped.)
What is the hypothetical sphere around the solar system?
Oort cloud
The name of the cloud with frozen comets?
Oort (Yes - that is what it is called)
Does the Oort cloud have rings?
No it does not. The Oort cloud is not a planet. It is a sphere of comets around our solar system.
What part of the Oort cloud is the atmosphere?
No part of the atmosphere of any planet is any part of the Oort cloud.
Is a oort cloud created by solar wind?
No. The Oort Cloud is "leftover" mass from the formation of the Sun and the planets.
Is Sedna a oort cloud?
no
Which has not actually been seen by astronomers the Main asteroid belt the Oort cloud or the Kuiper belt?
The Oort cloud
What theory suggested that comets originate in the Oort cloud and then travel in long elliptical orbits around the Sun?
Jan Hendrik Oort suggested that comets come from the Oort Cloud. This is sometimes called the Oort Hypothesis.
