Hello Everyone!
Where were we in the previous part of this? Well I shall further continue from there..........
Unlike our Sun, these did not form planets. The early solar system was filled with collisions due to high density of dust, lumps and gases. Several bits of matter gradually formed one or two big masses. In this way many big bodies are formed and still there were many remnants left over such as asteroids and at far off the disk, these formed what now we call comets. The ones which have nearly circular orbits around the Sun sustained collisions and avoided bumping into each other to form today's planets.
As earlier discussed, due to the arrangement of gases in the solar nebula formed on the basis of the molecular weights of the respective gases. This caused the lighter gases such as hydrogen and methane to go near the disk whereas the heavier elements come near the Sun, thus forming the gas giants and rocky balls. Since the formation, the probability of inter-planetary bumping reduced gradually.
This process also left a ring of asteroids in the form of a belt between the orbits of Mars and Jupiter. There are many theories why this is left as a ring rather than a planet.
So, as we discussed there were many remnants in the 'now' solar system. But there is still some probability of the 'tiny' bits of rocks hitting any planet and if these hit our home planet .................. it would be a disaster for the human race......... to be continued.............
