We are famous as the Comets

A ball of snow and dust with a nucleus at the centre and an extending tail, believed to be orbiting the Sun are called Comets. Comets are believed to be the residues from the process of planet formation that occurred around 4.6 billion years ago. The highly elliptical*elliptical*

orbits of the Comets compel the materials from the head of the comet to push away as they approach the Sun; thus resulting in the formation of the tail. Frozen gases like carbondioxide, ammonia and methane with the presence of dust and rocky materials in the water and ice forms the composition of the Comets. Kuiper belt and the Oort Cloud are considered to be the hosts of these celestial*celestial*
