Due to Earth's escape velocity, the minimum impact velocity is 11 km/s with asteroid impacts averaging around 17 km/s on the Earth. The most probable impact angle is 45 degrees. Impact conditions such as asteroid size and speed, but also density and impact angle determine the kinetic energy released in an impact event.

One way in which asteroid impacts have literally shaped Earth is through the resulting craters from large objects crashing into the crust. For instance, the Vredefort Dome in South Africa is the largest verified impact crater on Earth, estimated to be 300 kilometers wide when it was originally created.
