Impact events are occurrences where celestial objects, like asteroids or comets, collide with a planet, such as Earth. These events can vary in size and frequency, with larger impacts being rare but potentially catastrophic. For example, the Chicxulub impactor is believed to have caused the mass extinction of the dinosaurs around 66 million years ago. When an impact event happens, it can create craters, release massive amounts of energy, and lead to significant changes in the environment. The aftermath can include wildfires, tsunamis, and climate shifts, affecting life on the planet. Understanding these events helps scientists prepare for potential future impacts.
