Asteroid Impacts with Earth
Asteroid impacts have played a dramatic role in the history of Earth. Small and frequent events the size of Chelyabinsk meteor of 2013 are visible reminders that large and destructive events such as the Chicxulub impact 65 million years ago may have changed the course of life on Earth.
