What If 3I/ATLAS Collided with Earth?

This is a simulation of what would happen if an interstellar harbinger of doom smashed into Earth. That odd cigar-shaped asteroid is Oumuamua, the very first interstellar rock on record. 'Interstellar' means it came from outside the Solar System. The force of a collision with this rock would carve a crater the size of a city, vaporizing everything nearby. However, Oumuamua is not the worst interstellar rock.
