A coma
Its called the 'Coma'. Its is both the dust that the solar wind blows off the comet as well as gases expelled as the comet heats up.
The frozen portion of a comet consists mainly of ice, including water ice, carbon dioxide ice (dry ice), and various other frozen gases and compounds. This frozen portion makes up the nucleus of the comet, which is surrounded by a cloud of gas and dust when the comet is active.
The part of a comet around the nucleus is called the coma. It is a dense cloud of gas and dust that forms around the nucleus as the comet approaches the Sun and starts to heat up, creating a glowing halo.
When a comet's nucleus approaches the sun, the intense heat causes the frozen gases and dust on the surface to vaporize, creating a glowing cloud or coma around the nucleus. This cloud consists mostly of water vapor, along with carbon dioxide, ammonia, and other volatile compounds. The interaction of these gases with sunlight and solar wind creates the characteristic tails of a comet.
The bright glowing gases at the central part of a comet are called the coma. They are produced as the comet comes closer to the sun and the heat causes the ice and other volatile compounds on the comet's surface to sublimate, creating a cloud of gas and dust around the nucleus.

The heart, or center of a comet is called the nucleus. The nucleus is made of a solid piece of ice surrounded by a cloud of particles and gases.
Coma
a coma
A comet is made up of frozen gases, rock particles, and cosmic dust. As a comet gets closer to the sun, the heat causes the frozen gases to vaporize, creating a glowing coma around the nucleus.
The composition of a comet is frozen gases, dust, and rocks.
Comets are frozen collections of ice,dust and gases which moves around the Sun.
