While asteroids do occasionally enter Earth's atmosphere and burn up, there have been no confirmed asteroid impacts in the US.

There was a meteor that exploded over Chelyabinsk, Russia in 2013, but it did not impact the US.

It's important to remember that smaller asteroids burn up in the atmosphere and rarely cause significant damage. Larger asteroids are much rarer and are tracked by scientists.
