The Sun has a powerful gravitational pull. This, combined with the velocities of the planets, keeps the planets in orbit.
The Sun has a massive gravitational pull, it is strong enough to hold the planets in their place while they orbit it.
The Sun's Gravitational pull keeps the planets orbiting it, not flying into deep space.
