The Sun's Gravitational pull keeps the planets orbiting it, not flying into deep space.
The Sun has a powerful gravitational pull. This, combined with the velocities of the planets, keeps the planets in orbit.
the suns gravitational pull pulls them toward it but the planets try to escape its gravity

The pull of the Sun's gravity.
the gravitational pull from the sun keeps the planets and other small things in the orbit of the sun.(;
Because the Sun's gravitational pull keeps them in orbit.
The question probably means "What keeps the planets in orbit around the Sun?" The answer to that is : The Sun's gravitational attraction provides the force needed to keep the planets in orbit. This force doesn't pull the planets any closer to the Sun, but it stops the planets moving away (at a tangent to their orbits) due to their own velocities.
Gravity.

Gravity
The planets are kept in orbit around the sun due to the gravitational force between them. This force, which is a balance between the planet's inertia and the sun's gravitational pull, keeps the planets moving in a stable path around the sun.
