Original Note:
The hypervelocity of space objects intersecting Earth's path: for example, meteors enter our atmosphere at velocities of 6-26 mi/s or 11-42 km/s. The main reason why impact craters are symmetrically round is because it's the explosion of the impactor, not its collision. http://curious.astro.cornell.edu/about-us/38-our-solar-system/the-earth/impacts/47-why-are-craters-round-beginner. https://www.scientificamerican.com/article/why-are-impact-craters-al/
