Here's a breakdown:
* The Kuiper Belt: This region beyond Neptune is home to countless icy bodies, including many comets. It's like a giant frozen reservoir of comets.
* The Oort Cloud: This even more distant spherical cloud is thought to hold trillions of comets. It's the source of long-period comets, those that take thousands of years to orbit the Sun.
Only a small percentage of comets, known as short-period comets, have orbits that bring them closer to the inner solar system, including the region between Mars and Jupiter.
So, while it's true that some comets pass through the area between Mars and Jupiter, the vast majority spend their time much farther away from the Sun.
