What is the diameter of the Oort cloud?
The Oort cloud is estimated to extend from 2,000 to 100,000 astronomical units (AU) from the Sun. This vast distance means that the diameter of the Oort cloud can range from about 0.03 to 1.5 light-years.
The Oort Cloud is believed to be?
The Oort Cloud is believed to be a vast spherical region of icy debris extending far beyond the orbits of Neptune and Pluto. It is thought to be the source of long-period comets that occasionally enter the inner solar system.
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.
How far is the orrt cloud away from earth?
The Oort Cloud is a vast spherical shell of icy objects that lies far beyond the furthest reaches of our solar system, approximately 0.5 to 3 light-years away from Earth. This puts it at an estimated distance of about 30,000 to 190,000 astronomical units (AU) from the Sun.
Whats the angular size of long thin cloud that is stretched straight over head to the horizon would have?
The angular size of the cloud would depend on its length and how far it extends from directly overhead to the horizon. Assuming the cloud is very long and extends all the way to the horizon, it would have a wide angular size approaching 180 degrees when looking from directly underneath it.
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 cloud that surrounds the solar system?
The Oort Cloud is a region of space surrounding our solar system that is believed to contain trillions of icy objects, such as comets, extending out to about 1 light year from the Sun. It is thought to be the source of long-period comets that occasionally enter the inner solar system.
A spherical cloud of small icy fragments at the farthest reaches of the Sun's gravitational influence?
This icy cloud is known as the Oort Cloud and is located about 1 to 3 light-years away from the Sun. It is believed to be the source of long-period comets that occasionally enter the inner solar system. The Oort Cloud is a remnant of the early solar system and holds valuable clues about its formation.
Is Sedna a oort cloud?
Sedna is not located in the Oort Cloud. It is a trans-Neptunian object with a highly elliptical orbit that takes it far from the Sun, but it does not reach the distant reaches of the Oort Cloud.
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.
What color is an Oort cloud?
The Oort cloud is a region of space surrounding the solar system that is composed of icy objects. It does not emit light itself, so it does not have a specific color.
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.
Is Saturn part of the Oort cloud?
No. The Oort cloud is way beyond the orbit of Saturn. It's where many of the comets come from.
Is there any gravity on the oort cloud?
Any object will attract any other object - the comets of the Oort Cloud will attract each other and other objects; also, the gravity of the Sun will still be active at the Oort Cloud.
The oort cloud is the home of?
Comets.
Can people see the Oort cloud?
No
