Yes they do - they're mainly composed of tiny particles of 'space dust' and ice. When they get close to the sun. The 'solar wind' causes these microscopic particles on the comet's surface to detach and form the familiar 'tail'
Some comets are made of ice and dust.
Comets are made mainly from ice, with a slight mixture of small rocks and dust.

Comets.
Comets are body of ice, rocks and cosmic dust loosely packed together.Meteor is a streak of light caused when comets dust and meteoride burns up in the earth atmosphere before it reaches the ground.

Dust and gas 🌠☄
it is composed of ice and dust
In the "nebular hypothesis", clouds of gas and dust can lead to the formation of "planetesimals". Some of these become comets. So I think the question refers to "planetesimals".
Comets are made of mainly 3 parts -dust tail, ion tail and coma
Comets are composed of ice, dust, rock, and organic compounds. The ice includes water, carbon dioxide, and ammonia, while the dust and rock are made up of silicate minerals and metals like iron and nickel. Organic compounds found in comets include complex carbon-based molecules like amino acids and hydrocarbons.
Comets have a stream of gas and dust coming off them.
