Because they are formed of ice. Space is cold, so everything is frozen.
Comets are often referred to as "dirty snowballs" or "icy mudballs" due to their icy composition mixed with dust, rock, and organic compounds.
The vast disk of icy comets near Neptune's orbit is called the Kuiper Belt. It is a region of the outer Solar System that contains numerous small icy bodies and serves as a source of short-period comets.
They are called comets.
Oort cloud
Comets. The Oort Cloud is a vast region of space beyond the orbits of Pluto and the other outer planets where many comets are believed to originate. These icy objects can be pushed into the inner solar system by gravitational forces and become visible as comets when they approach the Sun.
Usually comets are icy as that is why you see the icy trail, but asteroids can be icy too.

you might be talking about Pluto, but its not considered a planet anymore.
