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.
Rocky asteroids. Icy comets often live in and come from the Kuiper Belt.
every 5-10 years.
The Oort Cloud
The correct answer is comet!
No. The Oort cloud is way beyond the orbit of Saturn. It's where many of the comets come from.
The Oort Cloud or the Asteroid Belt.
Comets.

Comets come from the Oort cloud and the Kupier Belt

Any object with greater mass than another can cause the lesser object to orbit it. Most of our comets come from the Oort Cloud, beyond Pluto, and they orbit our Sun.

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 space rock is the celestial space object that a meteoroid comes from.
