The Comets.
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.
The planet that fits this description is Pluto. It is considered a dwarf planet and is composed of rock, water ice, and frozen gases like methane and nitrogen, giving it a "dirty snowball" appearance.
because they are made of rocky balls and ice.
None, really. That might describe Pluto, but Pluto was recategorized as a "dwarf planet" a few years ago. "Dirty snowball" is also a good description of most comets.

The Comets.
Comets can be described as "Dirty Snowballs" and are composed of rock, dust, water ice, and frozen gases.

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.
Neptune's moon Triton could be described as a large dirty iceball. It is the seventh largest moon in the solar system and is covered with a mix of water ice and frozen nitrogen, giving it a dirty appearance. Its surface is also composed of rocky material, making it a unique and intriguing world in our solar system.
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.
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.
because they are made of rocky balls and ice.
Yes.
