because they are made of rocky balls and ice.
Comets, sometimes called a dirty snowball, are composed of ice covered by a crust. Rock, dust, and frozen gases such as carbon monoxide, carbon dioxide, methane, and ammonia make up the crust.
It's call a comet it's tail faces away from the sun so it is backwards.

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.
Dirty Snowball
All comets, we believe, are composed of a lot of ices such as frozen carbon dioxide, nitrogen, oxygen, water, and other gasses, with a lot of dust and some rocks. Science fiction writers Jerry Pournelle and Larry Niven described a comet as a "dirty snowball".
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.

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.
