Answer 2

Answer:

Comets, like planets, revolve around the Sun, but their orbits are very eccentric. A comet will occasionally travel close to the Sun. It has a longish tail that is wonderfully illuminated by sunlight before disappearing into darkness for years or millennia.

Explanation:

A comet is a small ice body in the Solar System that warms up and begins to leak gases as it gets closer to the Sun, a process known as outgassing. This causes a visible atmosphere or coma to form, as well as a tail. The influence of solar radiation and solar wind on the nucleus of the comet causes these processes. Comet nuclei are loose clusters of ice, dust, and microscopic rocky particles that range in size from a few hundred metres to tens of kilometres. The coma might be up to 15 times the size of Earth, while the tail could be larger than one astronomical unit.
