No, comets have been measured and their constituent material has been characterized. Calling it a dirty snowball is more a model.
snowball
because they are made of rocky balls and ice.
All comets, including Encke, are made of rocks, ice, dust, and frozen gases such as ammonia, methane, carbon monoxide and carbon dioxide. The center of a comet is sometimes referred to as a dirty snowball.
A comet, a dirty snowball actually.
its called a dirty snowball because of the wau it looks

What are comets made of? Gravity holds stars and planets together, but what holds the other (little stuff) together. Ionic bonds. And it turns out that are only 3 that seem to work: Water (ice), Silicon oxide rock, and ferromagnetic metals (iron, nickel, cobalt). Comets don't seem to have much metal, so "dirty snow-ball". In 1949, Fred Lawrence Whipple theorized that the nucleus of a comet is made of frozen water, rocky debris, and frozen gases. This was called the "icy comglomerate" theory and is now known as the "dirty snowball" theory. However, in 1999, the Stardust spacecraft was launched and in 2004 it retrieved tiny particles from the comet Wild-2's surface and came back two years later in a capsule, landing in Utah. Minerals that formed in the presence of liquid water were discovered, proving that, at some point, pockets of water had existed on the comet. This disproved the "dirty snowball" theory.

Yes.
Comets are often referred to as "dirty snowballs" because they are a mixture of ice, dust, and rocky particles. As a comet travels closer to the sun, the ice sublimates, releasing gas and creating a glowing coma (atmosphere) and tail. The appearance of a comet can resemble a snowball covered in dirt due to this process.

A comet is often referred to as a "dirty snowball" in science. Comets are made up of ice, dust, and rocky materials, giving them a reflective icy appearance when they are closer to the Sun.
A comet has this nickname.
A dirty snowball is a snowball that is covered in some type of filth. It is also what many people refer to a comet as.
