In our solar system , we have 8 planets which are revolving around Sun . All of them are round in shape . What could be the reason ?
Planets are round because their GRAVITATIONAL FIELD acts as though it is originated from the center of planet and it pulls everything towards it .
We know that before the formation of planets ,they were all covered with fluids . As time passed , the gravitational force which was strong at the centre of the body attracted everything toward centre.
At this point of time , the shape that could be taken up by the body is only SPHERICAL . Hence planets aret round and the shape was as it is after they cool down .
Now asteroids are having different shapes . This is just because they have a weak gravitational field .
