Expert Answer:

Dear student
 The Sun's gravitational pull on the Moon is over twice as great as the Earth's pull on the Moon; and it is this pull which keeps the moon in its trajectory around the earth. As the Moon revolves around the Earth, the Earth-Moon system moves around the Sun.
The earth-moon system forms a binary system. Both revolve in circles about the common centre of mass. The centre of mass of the earth-moon system revolves around the Sun in elliptical path.
We hope this clarifies your doubt.
