Expert Answer:

Earth is moving around sun under the influence of gravitational force in closed orbit.
 
Gravitational force is a conservative force.
 
"If the particle is moving in a closed path under conservative force acting on it, the work done is always zero"
 
Hence, work done on earth moving around sun is zero always.
