Other then its tail like figure in space (which is made of gas and dust), just about all comets have similar traits, such as how they are made of ice of very deep cold temperature, almost as cold as dry ice. Except the ice, they also have the similar trait of having dirt attached to them or even in them, which is why some people call comets a "dirty snowball."
No. It's a comet.
