The student is correct. Since the planet move around the stars orbit in a stable manner, the only force that can put it in space and make it move round the star will be the force of gravity from the star.

Lucian · Answer 2

The orbit of the planet is considered to be stable and does not change over time. This means that the force of gravity and inertia are perfectly balanced. Leading to forward motion of Planet and moons under force of gravity of some other large body (Most probably stars). This is in turns leads to formation of orbit.
