Heya user !!!
Here's the answer you are looking for
I don't agree that work must be done by Earth.
Because the force on earth is along the radius towards sun. But the displacement of the earth is tangential to the circular path followed by it.
Since the force and displacement are at right angles to each other, zero work is done by it.
Work done = FScosA where A is the angle between F and S.
So work done by Earth
= FS cos90
= FS × 0
=0

The force and displacement are at right angles so theta is 90.
W=FS cos theta
W=FS cos 90
W=FS 0
W=0
I hope it will help for u ☺.
