A combination of the bodies' inertia, and the Sun's gravitational attraction.
It is the balance between gravitational attraction and their motion.
why do we say that the solar system is an orderly arangement of heavenly bodies
The difference is semantic; the solar system is the collective identity of all bodies considered together as a whole, i.e., the Sun, planets, etc.; whereas the bodies would refer to each of those making up the solar system: the planet Neptune for example is "a" body in the solar system.
the major bodies of the solar system are mercuay,venus,earth and mars because they are before the asteroid belt
The sun is able to do this by exerting a gravitational force on the various bodies within our solar system.
The eight planets of our system are not considered small solar system bodies, to qualify as a planet in the first place means that they have to be quite large. Small solar system bodies are such things as comets, asteroids, meterorids, moons or minor planets.
There are millions of bodies that are part of our solar system, possibly billions or trillions.
There are various small bodies in the solar system .These include moon, asteroids, rocks etc.

But ... there are many bodies in our Solar system that have no atmosphere.
Yes, It holds the whole solar system together.

Please be more specific about which solar system.

Gravity holds the planets in their orbit
