The solid nucleus or core of a comet consists mostly of ice and dust coated with dark organic material, according to NASA, with the ice composed mainly of frozen water but perhaps other frozen substances as well, such as ammonia, carbon dioxide, carbon monoxide and methane. The nucleus may have a small rocky core.
2.Physical structure. A comet consists of five distinct parts: a nucleus, a coma (constantly escaping atmosphere), an extended hydrogen halo, a plasma (type I) tail, and a dust (type II) tail. Associated with the dust is a trail of large dust particles distributed in the comet's orbit./A comet is made up of four visible parts: the nucleus, the coma, the ion tail, and the dust tail. The nucleus is a solid body typically a few kilometres in diameter and made up of a mixture of volatile ices (predominantly water ice) and silicate and organic dust particles
3.Comets are very small in size relative to planets. Their average diameters usually range from 750 meters (2,460 feet) or less to about 20 kilometers (12 miles).
4.Comets go around the Sun in a highly elliptical orbit. They can spend hundreds and thousands of years out in the depths of the solar system before they return to Sun at their perihelion. Like all orbiting bodies, comets follow Kepler's Laws - the closer they are to the Sun, the faster they move.
5.The mean radius of the sun is 432,450 miles (696,000 kilometers), which makes its diameter about 864,938 miles (1.392 million km). You could line up 109 Earths across the face of the sun. The sun's circumference is about 2,713,406 miles (4,366,813 km).
