Expert Answer:

Dear student,

Orbit of  earth is elleiptical in reality.It can's get converted into a circular orbit just like that.The orbit is derived mathematically.Even while going away it is not ovecoming sun's gravity.Instead velocity changes in such a way that angular momentum remains constant making the motion possible.
