GENERAL KNOWLEDGE

Detailed explanation-1: -Comets are frozen leftovers from the formation of the solar system composed of dust, rock, and ices. They range from a few miles to tens of miles wide, but as they orbit closer to the Sun, they heat up and spew gases and dust into a glowing head that can be larger than a planet.

Detailed explanation-2: -Comets are small celestial bodies that have highly eccentric orbits around our Sun, meaning that their orbital paths take them close past the Sun, and then hurl them out deep into the Solar System, beyond Neptune’s orbit.

Detailed explanation-3: -Scientists sometimes call comets dirty snowballs or snowy dirtballs, depending on whether they contain more ice material or rocky debris according to NASA.

Detailed explanation-4: -Halley’s Comet is composed of about 50% rocks combined with about 50% ice. The ices on the comet appear to be composed mostly of water, carbon dioxide and ammonia. As Halley’s Comet approaches the Sun, its surface heats up and these ices sublimate off to create the comet’s tail.
