If a comet was to hit the earth, it would cause some serious damage. As an example even if something relatively small in size hit the earth, it would cause great damage. Small from an comet's point of size is around 200 metres in diameter and if this was to hit an ocean it would create devastation to all cities within a large radius.
Asteroid's are described as small or minor planets that are members of the solar system and move in what are called elliptical orbits. They are usually found between the orbits of Mars and Jupiter. The first Space Exploration started in 1957 with the launch of the first artificial satellite, Sputnik 1, sent into space by the Soviets. Since ancient times people have dreamed of leaving their home planet and exploring other worlds not known to man. Every era through out history has had a belief as to what the "heavens" are made form. The Greeks believed that the stars and space were made of a material called "Quitenses", and other culture once thought that the stars were made of their peoples passed away.
