Nope....they have dust, rocks and even some ice crystals in them that gives the appearance of a large solid ball. Sun shining on the mass gives it a glow and makes it appear solid.
It is a comet.
Comet Swift-Tuttle is a periodic comet with a nucleus primarily composed of rock, dust, water ice, and frozen gases such as carbon dioxide, carbon monoxide, and methane. When the comet approaches the Sun, these materials heat up and form a glowing coma and long tail as they are expelled into space.
A comet is a mixture of ice, dust, rocky material, and gases such as water vapor, carbon dioxide, and methane. As a comet approaches the Sun, the heat causes these materials to evaporate, creating the glowing coma and tail that are characteristic of comets.
A comet is made of ice, rock, and dust, and as it approaches the sun, the heat causes the ice to vaporize, releasing gas and dust that forms a glowing tail. This tail is what gives comets their spectacular appearance as they travel through space.
This description matches that of a comet. Comets are composed of ice, rock, dust, and frozen gases, and form a glowing coma and tail when they approach the Sun due to the heating and outgassing of these volatile components.
Comets consist of a nucleus made of rock, dust, and frozen gases like water, methane, ammonia, and carbon dioxide. When a comet gets closer to the sun, these ices vaporize and form a glowing coma and tail due to solar radiation and solar wind interactions.
The celestial form made of frozen gases and solid rock is called a comet. Comets typically have a nucleus of rock and ice surrounded by a glowing coma and sometimes a tail when they come close to the sun.
Comet.
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.

A comet is a tailed heavenly body composed of dust, rock, and ice that orbits the sun in an elongated path. When a comet gets closer to the sun, the heat causes some of its ice to vaporize, creating a glowing tail that points away from the sun due to solar wind.

A comet is a large body of frozen ice and rock that travels towards the center of the solar system. It orbits the sun in an elongated path, and as it gets closer to the sun, the heat causes the ice and rock to vaporize, creating a glowing tail that points away from the sun.
