Detailed explanation-3: -Read a brief summary of this topic The word comet comes from the Greek (kometes), which means “long-haired.” Indeed, it is the appearance of the bright coma that is the standard observational test for whether a newly discovered object is a comet or an asteroid.

Detailed explanation-4: -Some asteroids are round, some are elongated, and some even have a satellite. A comet also orbits the Sun, but unlike an asteroid, it’s composed of ice and dust. So, when a comet gets close to the Sun, its ice and dust content start to vaporize. So, when seen in a telescope, a comet appears fuzzy and/or has a tail.
