HOW DID THE SOLAR SYSTEM BEGIN...?

Scientists think there are two ways in which the solar system could have begun. According to the nebular theory, and the solar system was born from a great cloud of whiring gases. The attraction of gravity drew the atoms of the gas closet together. As the gas condensed into a ball, the circular motion increased. Rings of matter were left spinning around the central mass. These  condensed to form the planets, and the central ball of gas become the sun.

COULD THERE BE A COLLISION OF PLANETS....?

Are you guys afraid or fear about the collision of planets..?

Simply the answer is NO. There is no reason for such a fear. The planets and stars are so far away from each other, even though we don't realise it. Let's imagine that your own head is the Sun, both in its size and location in the solar system. Your head is then in the centre of a number of rings of different size. These rings are the orbits which the planets travel around the Sun. With your head as the centre, Mercury, revolving in the nearest ring, is six metres away from you! it is about as large as the dot at the end of this sentence.(Remember, the size of your head is the size of the Sun.)
