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.
No part of the atmosphere of any planet is any part of the Oort cloud.
The outer Oort cloud. (The inner Oort cloud is believed to be disk-shaped.)
True. We think; the Oort Cloud is a hypothesis, because so far we are unable to detect small dark objects so far from the Earth. We have never actually detected anything in the Oort Cloud. But long-period comets come from SOMEWHERE, and Jan Oort's idea of a "cloud" of primitive objects makes sense.
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.
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.
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.
As of now, we have not observed any objects or phenomena beyond the Oort Cloud. The Oort Cloud is the theoretical boundary of the solar system, so anything beyond it would be in interstellar space. Technology limitations make it difficult to observe objects at such extreme distances.
A black hole could potentially disrupt the orbits of objects in the Oort Cloud through its gravitational pull, but it is unlikely to "suck in" the entire cloud. The vast distance of the Oort Cloud from any known black holes reduces the probability of such an event occurring.
No. The Oort Cloud is "leftover" mass from the formation of the Sun and the planets.
We do not believe that any life currently exists in the Oort Cloud. Eventually, of course, human beings will go there to harvest raw materials to build space habitats.
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.
Jan Hendrik Oort suggested that comets come from the Oort Cloud. This is sometimes called the Oort Hypothesis.
