plz tell me please it's urgent..
We know that earth and sun has its own gravitation field and therefore sun attracts every planet toward it but he cannot attract them towards it as all planets have their own gravitation field to held them at their position so my question is if sun is pulling earth and earth is pulling sun towards it than they should remain constant at their position so why it moves? as they should remain constant at their position as both are pulling each other so why earth start rotating from its position as it's bound by sun's gravitational field so it should remain constant at its position so why it's start moving from its position...?? and how??​
