comet definition An object that enters the inner solar system, typically in a very elongated orbit around the sun. Material is boiled off from the comet by the heat of the sun, so that a characteristic tail is formed.
Comets are small celestial bodies that orbit the Sun. They are primarily made of dust and ice. Considered to be remnants of the formation of our Solar System, most comets belong to the Kuiper Belt, a region beyond the orbit of the planet Neptune.Comet PanSTARRS was visible in early 2013.Comet PanSTARRS C/2011 L4 was visible to observers on Earth in early 2013.hey are primarily made of dust and ice.
