Well satelite are nearer to earth than space objects.

Thanks for the first few answers but why space objects are pulled and smash the earth surfaces (don't know the name, meteorite i think). And why do satelites orbit the earth instead being pulled to the earth.

Satellites Are Always In A Caught State

Satelites are carefully thrown into an orbit that equates gravities pull back to Earth. Sometimes when this process is corrupted satelites do fall from the sky. An asteroid is a rock that has been thrown into space willy nilly. Sometimes they also fall to earth or other planets and moons.

David Copperfield has a trick for you.

Satellites are caught by earth's gravity. That's why they fall around the earth. If they weren't caught by gravity they would sail away into space in a straight line. But they also have to be moving fast enough "sideways" that they are falling past the earth as fast as they are falling towards the ground. That way, they keep "missing" the earth; by the time they fall all the way to where the surface was, they have moved sideways far enough that they are past it. But because they are close enough to be "caught", they keep curving toward the earth as they are falling.

BTW, every object in the entire universe is attracted at least a little bit by the earth's gravity. But unless they are very close, it's generally too weak to pull them to the earth, or earth to them.

If what your asking is about artificial satelites....

it is that these artificial satelites are in the exosphere, the outermost layer of earth's atmosphere, that they are bound to stay in orbit rather than fall. But sometimes, satelites are intentionally crushed down to earth's crust, mostly in oceans, because they are too old or dangerous to operate.

On the other hand, our natural satelite, the moon, has its own gravity to keep it in orbit while not falling even into our atmosphere.

Gravity is a force that depends on distance. Satellites are close to the Earth, and are most strongly influenced by the Earth's gravity. Farther objects are less influenced, and are not "caught". You've got it backwards.

And of course they ARE caught by the Earth's gravity, it's just that they are moving fast enough to fall AROUND the Earth rather than to the Earth's surface.

satelites are in a proper orbit around the planets and the space objects are at random so they keep on changing their distances around planets unlike in the case of satelites

They ARE caught in gravity but they are also given just enough forward propulsion to counter the constant gravity which allows them to stay in orbit.

When they are no longer useful, they stop worrying about the satellite and allow it to fall into the rigors of Earth's gravity and burn up in the atmosphere.

Objects in space are not caught by earth's gravitational force because they are outside the influence of earth. Satellites are way out in orbit, and not subject to the force of gravity.

They are caught.
Falling toward Earth plus velocity equal orbit.
