A dirty snowball is a comet, which is composed of ice, frozen gases (such as carbon dioxide, methane, ammonia), and rock. When a comet travels close to the Sun, the heat causes the ices to vaporize, creating the tail that we see from Earth.
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.

Yes.
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.
A comet has this nickname.

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.
"DIRTY SNOWBALL" : a description of a "comet", which ordinarily orbits the Sun and partially disintegrates (from heating) to form its "tail" as it gets closer to the Sun.

it is made up of ice and dirt and is therefore also known as a "Dirty Snowball"

A comet is often described by Astronomers as a 'Dirty Snowball'. This is because a comet comprises of Ice, from frozen gases mixed with dust and other particulate matter, collected on its orbital path.
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.
