Actually, there's a small chance that an
asteroid will be pulled by Earth's gravity.
It's just that these asteroids are usually far
away from us (they're mostly in the asteroid belt
between Mars and Jupiter), and Earth's gravity is
not strong enough to affect them. However, once in
a while, an asteroid gets a little too close to
One of the most famous asteroids is the one
that struck Earth during the time of the
dinosaurs, which scientists have blamed for their
extinction. I hope I answered your question. Good
luck with your studies!
