Dinosaurs died
The debis from Earth was pulled into orbit to form today's moon.
Dinosaurs died
Extinction of the dinosaurs.
Depends on the mass of the asteroid
They were formed when the earth's plates collided with each other.

it shaped the moon
Most of the asteroids in the asteroid belt have stable orbits around the sun well beyond any gravitational influence from Earth worth noting.
An asteroid to happen? Asteroid cannot 'happen'. It can collide with earth, or any other object with mass, though.
a currently popular theory is that the moon came about when an asteroid collided with earth, ejecting what is now the moon into near-earth orbit.
it collided with earth. thea is now the moon
Most asteroids are in the Asteroid Belt between Mars and Jupiter. But a few do come close to the Earth; these are called Near Earth Asteroids. You can see a list of NEAs, and the dates that they will come closest to the Earth, at www.spaceweather.com. Asteroids and comets have collided with the Earth in the past, and someday one will collide with Earth in the future. Depending on the mass of the asteroid, the damage could be catastrophic. 65 million years ago, scientists now believe that an asteroid or comet hit the Earth, causing the extinction of the dinosaurs and most life on Earth.
Dinosaurs died
Earth did not exist 65 billion years ago. However 65 million years ago an asteroid collided with Earth, triggering a mass extinction even that wiped out a wide variety of organisms, including the dinosaurs.
Smaller. Something as big as the Earth would have so much gravity that it would probably have collided with something else and been eliminated
A large comet or asteroid striking earth
Because it was headed towards earth. It was bound to happen.
wouldn't matter because we would be extinct and no one would be around to worry about it.
