SOLAR SYSTEM

Detailed explanation-1: -Comets are cosmic snowballs of frozen gases, rock, and dust that orbit the Sun. When frozen, they are the size of a small town.

Detailed explanation-2: -Comets are defined as icy bodies of frozen gases, rocks and dust left over from the formation of the solar system about 4.6 billion years ago. They orbit the sun in highly elliptical orbits that can take hundreds of thousands of years to complete.

Detailed explanation-3: -A comet is com-posed of dust and rock particles mixed with frozen water, methane, and ammonia. Halley’s comet was last seen from Earth in 1986. English astronomer Edmund Halley realized that comet sightings that had taken place about every 76 years were really sightings of the same comet.

Detailed explanation-4: -Comets are composed of frozen water and gases, dust and rock, and organic materials. Comets follow an elliptical orbital path around our Sun. Heating from our Sun vaporizes frozen gases and water on the surface of comets.

Detailed explanation-5: -Comets have been likened to dirty snowballs, and that’s a pretty apt description. They’re loosely bound masses of ice, dust and rock. The core or nucleus of a comet is relatively small-often just a few miles across. It consists mostly of water ice and frozen carbon dioxide, carbon monoxide, methane and ammonia.
