It is solid ice and rock. The ice melts as it's coming near the sun though.
The nucleus is the solid part of a comet.
We believe comets have a composition like a dirty snowball. They contain alot of ice and dust. The ice does trun into a gas when the comet approaches near to the sun and this causes the comet's tail to form.
The center of a comet is called its nucleus.
Nucleus: The solid core of a comet composed of ice, rock, and dust. Coma: The gas and dust envelope that surrounds the nucleus when the comet approaches the sun. Tail: The long stream of gas and dust particles that is pushed away from the coma by solar radiation pressure, always pointing away from the sun.
a comet
The solid object at the head of a comet is called the comet nucleus.
The nucleus and the coma compose the core of the comet. The nucleus is the solid, rocky part at the center, while the coma is the surrounding cloud of gas and dust that forms as the comet gets closer to the Sun and begins to vaporize.
Rock: asteroid. Liquid: none. Gas: comet.
The dense section of a comet's head is called the nucleus. It is composed of ice, rock, and dust, typically ranging in size from a few hundred meters to tens of kilometers. The nucleus is the solid core of the comet from which gas and dust are released to form the comet's coma and tail when it gets closer to the Sun.

The Comet's Tail forms when sunlight causes the Comet's ice to change to a gas. The gas or ion , tail of a comet streams from the comet's head, carrying with it dust particles. The solar wind electrically charged particles, expand away from the sun pushes the gas away from the comet's head. Regardless of where its going the tail points away from the sun.
The length of the comet tail increases as it approaches the Sun because the heat causes volatile materials within the comet, like ice, to sublimate (turn directly from solid to gas). This process releases gas and dust particles, creating a long tail that points away from the Sun due to solar radiation and solar wind.
