Most are thought to come from the kuiper belt, further out than the orbit of Neptune. Long term comets may also come from the Oort cloud, which is further out still.
The Oort Cloud.
The sun makes everything in the solar system visible.
they were formed the same time as the planets (after our sun)
No. Most comets are about the same age as the solar system as they formed with it.
Not necessarily! System with one sun (star) at its centre is called solar system. A solar system may have anything. Our solar system has, of course eight planets, asteriods, comets. But any other solar system in the cosmos may have different things,
.... errr - well comets.

All the comets that have been seen in history were in the solar system and most still are.
There are no visible comets at this time.
I scientifically believe that comets are closer to the outer part of the solar system.

comets can be found in the oort cloud to the south of Pluto
No, comets have tails due to solar radiation subliming ices and other volatile substances into a temporary atmosphere that is tail shaped due to the comets velocity.
It helps us to know about the solar system's early history. That's because we think comets are leftovers from the formation of the planets, etc. They are very old, primitive bodies, like the asteroids.
