Gravity and motion. Gravity pulls the planets in and keeps them from flying away, while the velocity of the planets keeps them from being sucked in completely.
The solar system stays together due to the gravitational force exerted by the Sun. Gravity keeps all the planets, moons, and other objects in orbit around the Sun. It is this balance between the outward force of the planets' motion and the inward force of gravity that maintains the stability of the solar system.

The suns gravitational pull.
Gravity.
The force of the Sun's gravity keeps them in their orbits.
Neptune stays in orbit around the Sun due to the gravitational pull between the two bodies. The Sun's gravity keeps Neptune in its orbit, just as it does for all the other planets in the solar system. This balance between the Sun's gravitational pull and Neptune's orbital speed keeps it from moving away or falling into the Sun.
The sun holds celestial bodies in the solar system through its gravitational pull. This gravitational force keeps planets, moons, asteroids, and other objects in orbit around the sun. The balance between the sun's gravity and the forward motion of the celestial bodies keeps them moving in stable orbits.
In our solar system, the sun provides heat and light to the planets; also, the gravitational attraction of the sun keeps the celestial bodies in the solar system in orbit. Without the sun, there would be no solar system.
it keeps it in orbit
do it by your self dums dood
