Understanding Comets: Structure, Behavior, and Famous Examples

Comets are celestial bodies in the form of balls of ice and dust that orbit the sun in our solar system. When a comet approaches the sun, its heat causes the comet’s ice and dust to evaporate and form a tail that appears to glow. This tail is usually pointed away from the sun by the pressure of the solar wind, which is called the solar wind.

Comets consist of a dense core of ice called a nucleus, and as they approach the sun, the layers of ice and dust around the nucleus form a coma that can be seen glistening in the sky. Comets can move in long elliptical orbits and have varying periods of time to complete one rotation around the sun.

Many comets are known because they have repeated orbital cycles and can be observed from Earth for a certain period. Some comets are visible to the naked eye when they are close to Earth, while others are visible only through telescopes. Some examples of famous comets are Halley’s Comet, Hale-Bopp’s Comet, and ISON’s Comet.
