1 out of 7000 is very very small but not as small as I thought it was gonna be.
What would happen if a 40 meter asteroid hit earth?
The Tunguska comet in 1908 is estimated to have been a little bigger and mostly composed of water. It would be a very big event, kind of like a small atomic bomb.
Imagine if you will.. A giant hunk of space rock. A planet in its crosshairs. moving ever closer at ludicrous speed and accelerating.
One of these days .. it’ll take more than Bond-o and PROACTIV to fix the crater.. The size? Depends where it lands and the angle.. Think small hydrogen bomb tonnage energy potential.. Maybe.
The average density for an asteroid is 2g per cc. That gives it a total mass of about 536 million kg. You can expect an impact velocity of around 30-40 km per second. That gives it an energy anywhere between 57 and 102 megatons of TNT. Big, but not earth-shattering. Not an extinction event.
I can see the ICR news article now:
An asteroid came blazing out of the dark skies
at 0454 this morning over and crashed into the
Texas city of Beaumont, striking with the
intensity of a low yield nuclear weapon. Most
heavily damaged was the suburb of Wellspring.
ICR experts have determined that for an asteroid
to be steered so precisely as to hit a tiny pinpoint
on the surface of the planet, when there are uncountable
other sites that might have been hit, would require an
intelligence surpassing anything mortal and could
only have been a Act of God.
Astrophysicist Benjamin McLarkey told ICR that if
proof were needed that a deity was behind the
creation and control of the universe, this was it.
