The speed and mass of this asteroid
Background:
In the world of Krynn (Dragonlance) there was this worldwide catastrophe, the Cataclysm.
What happened: Gods became angery to a single person, so they threw an asteroid at him, obliterating half the known world in the process.
The World pre and post Cataclysm
KABOOOM! (that purple thing is where the asteroid hit the planet)
Information
I want to make a campaign where the gods are revealed to be beings with way higher technological levels, so in order to make this setting change proper, I should really figure out the mass and the speed of that meteor.
- I calculated the crater to be approx 637,42 miles in diameter.
- Depth is unknown.
Question
What would be the real side-effects of this level of destruction? How big would the asteroid have to be, to create this large crater, that gets filled in by the ocean later?
