Mostly black. That's because it is so far from the Sun that the Sun itself only looks like a fairly bright star, and there would be no light there to enable you to SEE anything.
And the Oort cloud is "only" a theoretical concept; we believe that something like it must exist as a source for the comets that we occasionally see, 4.6 billion years after the birth of our solar system. (Comets that come close to the Sun can't last for a million years!) So we've never actually detected anything out there, which isn't surprising - because the stuff out there is so far away that we'd have a VERY difficult time detecting it even with a telescope 100x more powerful than the Hubble.
To summarize, then, the Oort cloud is very far away, and populated (we think) by mostly small objects spread out over an enormously vast area. So what color would it be? Black.
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.
Jan Hendrik Oort suggested that comets come from the Oort Cloud. This is sometimes called the Oort Hypothesis.
Comets are believed to have originated from asteroids in a sort of 'cloud', called the 'Oort Cloud'. It is thought all comets come from the Oort Cloud, which is a cloud of asteroids beyond the Kuiper Belt beyond Neptune. When one asteroid is knocked off from its orbit from the Oort Cloud, it makes really long trips around the Sun, which is why it becomes a comet. All of the asteroids in the Oort Cloud have some type of ice on them, since they are so far away from the sun that everything in the Oort Cloud seems to freeze.
There is no scientific evidence to support the claim of a planet-sized object like "Nibiru" passing through the Oort Cloud. The Oort Cloud is a theoretical region of space beyond the planets, containing icy bodies, comets, and debris. It is highly unlikely that such an event would create a hole in the Oort Cloud.
I presume you are referring to the 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.
The outer Oort cloud. (The inner Oort cloud is believed to be disk-shaped.)
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.
No. The Oort Cloud is "leftover" mass from the formation of the Sun and the planets.
No part of the atmosphere of any planet is any part of the Oort cloud.
Jan Hendrik Oort suggested that comets come from the Oort Cloud. This is sometimes called the Oort Hypothesis.
No. The Oort cloud is way beyond the orbit of Saturn. It's where many of the comets come from.
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.
