The sun
Jupiter has an effect on the orbits of the asteroids, but I wouldn't really say that's what holds them in the area beyond Mars.
No, the gravity of the Sun primarily affects the planets and large objects in the solar system. Asteroids beyond Mars are influenced by the gravitational tug of large gas giants like Jupiter and Saturn, as well as interactions with other objects in the solar system. The Sun's gravity does play a role in the general structure and dynamics of the asteroid belt, but individual asteroids are not held in place by it.
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.
The area at the edge of the solar system is known as the heliopause. It marks the point where the solar wind from the Sun meets the interstellar medium of the galaxy. It is where the influence of the Sun ends and the influence of interstellar space begins.
The region beyond Earth's atmosphere is known as outer space or simply space. This area is vast and contains stars, planets, comets, asteroids, and other celestial bodies. It is a near-vacuum environment with little to no atmosphere.
There is no definite area where asteroids are concentrated in but within our solar system, the asteroid belt should have the highest amount of asteroids.
We call that the "asteroid belt".
gravity zone is the area where gravity exists.
In a low-gravity area, it would generally be easier to do activities that involve moving or lifting objects, as there is less force pulling you down. In a high-gravity area, it would be more challenging to move or lift objects due to the increased force of gravity pulling you down.
The asteroid belt, which consists of millions of individual asteroids of varying sizes, is located between the orbits of Mars and Jupiter.
