They are from extreme outer parts of the solar system (known as "Kuiper belt") and from a huge cloud of comets lying far beyond the orbit of Pluto, completely surrounding the Sun (known as "Oort cloud").

In what region are most comets at?
We generally believe that comets with orbits of 200 years or less, traveling in the ecliptic plane, come from the Kuiper Belt. Those comets with longer orbits, or that travel at angles to the ecliptic plane, come from the Oort Cloud.
What is the source of the solar system's comets?
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.
Do all astronomers think that Pluto is a planet?
No. It was categorised as a dwarf planet in 2006, but not all astronomers agree with that decision.
Are most comets found in either Oort cloud or the asteroid belt?
Rocky asteroids. Icy comets often live in and come from the Kuiper Belt.
Most meteor showers are associated with the orbits of?
Comets
What tool do you think helped astronomers study the sky is the most?
The telescope helps astronomers the most when studying the sky.

What did most ealy astronomers think made up the universe?
Our Solarsystem
Why do astronomers name comets?
The same reason why people name anything - to distinguish between them. Comets are named with the year of discovery, a serial number, and the discoverer's name. Most "comet hunters" are amateur astronomers who live for the fleeting fame of having discovered a comet; being an "amateur comet hunter" isn't a job that pays anything. The fame of having a comet named for them is their only reward.

Do astronomers get summer breaks?
U spelled break wrong, but i most certainly do think they dont get breaks.
What celiestial body do comets orbit?
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.
Do all astronomers think Pluto planet?
No. Most follow the new IAU definition of a planet which excludes Pluto.
Are comets from other galaxies?
No, they are not. They come from regions of asteroids that exist within our own solar system. Long period comets, the ones that appear once in thousands of years, probably come from the Oort Cloud, a spherical cloud of small icy asteroids believed to exist at the farthest outer reaches of the solar system. Short period comets like Halley's probably come from the Kuiper Belt, a ring of asteroids just beyone Neptune's orbit. The minor planet Pluto is the most famous Kuiper object. Not all objects in the Oort Cloud and Kuiper Belt are comets; in fact most are not.
