ALL ABOUT COMETS

Comets, like asteroids, are small celestial bodies that orbit the Sun. However, unlike asteroids, comets are composed primarily of frozen ammonia, methane or water, and contain only small amounts of rocky material. As a result of this composition comets have been given the nickname of "dirty snowballs."

Some comets have highly elliptical orbits that bring them relatively close to the Sun. As these comets near the Sun the ices found within them melt and brilliant features are formed. Below is a list of these features.

Below is a list of these features.Nucleus: the nucleus of a comet is composed of ice and rocky material. The nucleus of most comets ranges from about 10 to 100 km in diameter, though they can be as large as 100 km in diameter.

These gases are usually a mixture of water vapor, ammonia, carbon dioxide.

The dust tail is the most visible part of a comet.
