Gravitational force
It's because of the sun's pull of gravity and force, which is so strong, pulls a lot of heavenly bodies that are around it.
The mass of the planet, and the distance from the center of gravity. Gravitational pull is a relation between the mass of two bodies and their distance apart.

Gravitatonal pull
A pull. Gravity is always attractive, so in the long run, gravity is the deciding factor in the motions of planetary bodies
Which type of pull? This is still gravity, but now it's the Moon's gravity or "Lunar gravity".
It keeps them in orbit around the sun.
Yes, The Sun Is always moving due to gravitational pull from heavenly bodies in the solar system.
The planets mass creates gravity which pulls it into a spherical shape. This is the difference between planets and other heavenly bodies such as moons and asteroids. To be defined as a planet, a body must have enough gravity to pull itself into a spherical shape and it's gravity must be sufficient to clear its area of other debris.
