Question

We all know that SUN and the EARTH has gravity which attract particles , then the sun and the earth must be attracted towards each other and get crashed Why is that not happening??

Answer 1

the earth and sun are attracted towards each other. the secret to why they never crash lies in the revolution of the earth. the gravitational force of the sun acting as the centripetal force is counterbalanced by the revolution of the earth acting like the fictitious centrifugal force. thus there is an equilibrium which is established and they do not crash.
