WHEN WILL ASTEROID HIT US?

ASTEROIDS ARE JUST ROCKS FORMED FROM THE REMIANS OF DUST AND ROCK MATERIALS FROM THE SOLAR SYSTEM, THE SUN IS THE MOST GRAVITAITONAL BODY IN THE SOLAR SYSTEM AND THIS STAR IS ABLE TO GRAVITATIONALLY ATTRACT  ALL THE  ASTEROIDS INTO ORBIT  AROUND HER IN BILLIONS OF MILES AWAY AND ALSO  THAT  EACH OF THESE BILLIONS OF MILES, THEY ARE ABLE TO TRAVEL AND ALSO SPIN ON THEIR OWN AXIS, OR JUST EVEN THAT EACH OF THEM COULD BE EVEN TRAVELING AT THE DISTANT SPEEDS AND EVEN JUST HIT US....
SOME OF THESE  ASTEROIDS TEND TO BE EVEN JUST CLOSER ON US, BUT THAT DEPENDS AT THE KEY ROLE THAT OUR PLANETS GRAVITY IS ABLE TO PLAY ON THAT ASTEROID, AND ALSO THAT, IF JUST ABLE TO CONTROL THE WHOLE PULL OF THE ASTEROID AND DRAG IT, TOWARDS THE SURFACE OF THE PLANET.

ASTEROIDS WILL HIT US, WHEN THE EARTHS GRAVITY IS GOING TO ATTRACT THEM, WHEN THE ORBIT AROUND THE SUN IS SO UNSTABLE.
