Comets are made up of left over matter from the formation of the solar system.
The Solar System
Asteroids, meteoroids, comets and kuiper belt objects.
They seem to be bits left over from the formation of the Solar System about 4.5 billion years ago.
Comets contain various types of ice (water and also other frozen liquids or gases) which sublime to vapor when the comet approaches the inner solar system.

It is called "The Oort Cloud"
If you mean all our planets and comets, it's called the Sun. It is called "The Solar System".
Most are unchanged since their formation in the solar nebula.Correct
Comets are made of ice (frozen water and gases) and dust that for some reason didn't get incorporated into planets when the solar system was formed. The shape of a comet's orbit is oval or egg shaped, the scientific term for it is elliptical.Read more about Comets by nineplanets.org
It's a member of the Kuiper belt (the inner part of the Oort cloud), home of comets and leftovers from the formation of the solar system.
