A mechanical working model of the solar system is called an orrery. Many observatories have them, as do thousands of individuals.
A solar system could simply have one planet, the most important thing is that it has to have a sun with celestial bodies that revolve around it in its gravitational field to be classified as a solar system.
No, the asteroid belt is located within our solar system. It is a region between the orbits of Mars and Jupiter where many small rocky bodies, known as asteroids, orbit the Sun.
The main ones are: The Sun, Mercury (a weak field only), Earth, Jupiter, Saturn, Uranus, and Neptune. So, that's seven bodies.
Earth and our solar system formed approximately 4.6 billion years ago, which is around 4,600 million years ago. This formation occurred from the gravitational collapse of a region within a large molecular cloud. The process led to the creation of the Sun, planets, and other celestial bodies in our solar system.
Heavenly bodies, by their very definition, are not "in the world" - they are in the heavens - that is, they are out of this world. Heavenly bodies include the Sun, the moon, the planets of the solar system and other stars and their planets. They are - literally - too many to count.
There are so many people studying about the Solar System and the whole universe!...
It normally depends upon what it is. Even though they aren't considered heavily, there are many objects out there such as dwarf planets and comets.

135. This only counts celestial bodies such as the sun, planets and moons. There is 1 star (sun), 8 planets, 123 moons and 3 unclassified bodies (Pluto and others).
But ... there are many bodies in our Solar system that have no atmosphere.
Earth has one moon, the Moon. I don't know what you mean by "heavenly bodies".

Mercury. There are many smaller bodies orbiting the Sun but they are not classed as planets.
I'm not sure you can really call that a "body" but for me it's definitely Black Holes - and many scientists share that opinion :)
