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.
The sun's gravity holds the planets in their orbits. It also holds other space objects in their orbits, such as asteroids.

Gravity :) (Gravity also holds the outer planets tightly to the Sun.)
Yes they are the sun has gravity that holds the planets in place.
The gravity that keeps the planets in orbit is the sun's gravity, which is a product of the sun's mass.

Planets move away by gravity not holding it together and also gravity holds planets together
Simple. Gravity! The planets are dragged in by the gravity of the sun.
Gravity holds everything together in the galaxy. (planets)

There is gravity in space. Gravity is what makes orbits possible.
