Gravitational force is not absent in space. In fact, gravitational force is what keeps the universe together. The planets orbit the sun based on gravitational force.
Planets and moons remain in their orbits because of the gravitational pull other bigger planets or stars have on them, for example the Earth stays in its orbit because of the gravitational force it is subjects to created by the Sun, and the moon stays in its orbit because of the gravitational force it is subject to created by the Earth. It's all about gravity and force.
Sun's gravitational force keeps all the planets bound to the sun
It's true that gravity holds planets in orbit. However, this is due to the gravitational influence of the sun, not the gravitational influence of other planets.
Gravitational pull is less for Mercury, Venus, Mars and Uranus. And th eother planets have higher gravitational pull.
Planets orbit around the Sun because of the Sun's gravitational force, it makes the planets move by its gravitational force.
Their mass is. Gravitational force is a force between masses.
Planets and moons remain in their orbits because of the gravitational pull other bigger planets or stars have on them, for example the Earth stays in its orbit because of the gravitational force it is subjects to created by the Sun, and the moon stays in its orbit because of the gravitational force it is subject to created by the Earth. It's all about gravity and force.
The greater the mass, the greater the gravitational force.

Gravitational Pull?
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.
That explanation is logical however the sun DOES have a gravitational force because all the planets orbit around the sun.
gravitational
The sun's gravitational force is so much greater than that of the planets because the sun has so much more mass (matter) than the planets. Of all the matter in the Solar System, 99.8% is in the sun and only 0.2% is in all the planets combined.
