The asteroid spaceship is made from 'hexagonal basalt'. On Earth, basalt is from magma that came to the surface as lava and cooled there; magma that cools before reaching the surface becomes granite. When basalt cools relatively quickly from the top down it can fracture into generally hexagonal columns ( think of how a mud field dries into fracture plates), now think of those plates being 30 to 130 feet thick.
