As another poster mentioned, each planet tends to hold a certain distance. So you might ask "how do they maintain that distance? Why won't gravity just make the planets collide?" Before I get to that, quick backstory.. 
 
There are 3 parts to this issue.
First, in the young solar system, there were such collisions on regular basis. These collisions were essential in making the particles coalesce to form larger and large lumps of mass, which we call planets. These planets gained enough mass that its gravity helped clear out the path in its orbit around the sun. That’s how planets formed and the gravity cleaned out the inner solar system where the planets are located. Luckily, we don’t have to worry anymore about any dangerous mass of asteroids still present in inner solar system.
 
Second.. So how do these planets maintain their respective orbits around the sun? Every planet is in something called 'free fall', much like how the International Space Station (ISS) stays in orbit around Earth rather than just falling back to Earth. As the ISS is getting tugged towards Earth’s center of gravity in the core, ISS is also accelerating. As it accelerates, it speeds up. The acceleration essentially forces the ISS to move perpendicular to the acceleration (overall, it would be sideways). If Earth’s gravitational tug would shut down for a moment, the ISS would shoot out into space. If the sideways acceleration stopped for a moment, the ISS would come straight down to Earth. Both things keep the ISS in free fall & locked into Earth’s orbit, albeit maintaining the orbit. Similarly, each of the planets are in free fall around the sun, and they maintain their orbits through that.
 
Third.. So how do these planets keep from colliding with each other? The simple answer is that their free-fall orbits are in lock with the sun (or more specifically, the solar system’s center of gravity, which happens to be in the sun). Unless if the sun’s gravity changed for whatever reason or if something happened to the acceleration & impacted free-fall, the planets will not collide. In fact, since the inner solar system cleared up of asteroids billions of years ago, all the planets have been in same constant orbits at same revolving speeds around the sun. Remember, Newton’s law of inertia states that an object in motion will stay in motion at same velocity/speed unless acted upon by an external force. That’s how the planets maintain their distances, motion, and keep from colliding with each other.

Bro planets will not collide here are the following:

1 :there is an huge space between planet to planet

2: the gravitational force act such as it will not collide.

3 :due to zero gravity in the the planets will not move.

Hope it helps you....!☺️☺️
