Hexagonal craters.

How can the hexagon shape be formed due to meteor/asteroid impacts?

How are irregular polygons and similar angles of the crater rim be formed in very different local conditions from very different asteroid types?

Hexagonal craters on Earth, planets, moons and asteroids

Hexagonal craters shape formation

They look to be created as a natural shape, one that nature constantly forms in very different physical environments. Electromagnetic geometry? Atomicmagnetic geometry? Morphicfield geometry?

Mark Slater in a couple of hexagonal comments has suggested some form of magnetic/atom process

Electric Universe theory about hexagon craters and possible explanations of how they were created.

What other possible sources for their formation and shape are there?
