impact event

An impact event refers to a significant occurrence where a celestial object, such as an asteroid or comet, collides with a planet or moon. These events can cause substantial changes to the environment, including massive explosions, climate shifts, and even extinction of species, as seen with the dinosaur extinction event 66 million years ago. Impact events are essential in understanding the history of Earth and other bodies in the solar system, revealing how such collisions have shaped surfaces and influenced life over millions of years.
