Here's what an asteroid collision with Earth might look like from space.
A massive impact could cause large tsunamis or what is called an impact winter where a large amount of dust collects in the stratosphere and blocks sunlight. An impact winter may have caused the extinction of dinosaurs.
An asteroid this large would create a crater of a little more than 1/2 mile wide according to an Impact Earth chart developed at Purdue University.
