At half the speed of light a ping pong ball (40mm in diameter:2,7 grams) will have the same kinetic energi as the moon. Auch.

“The impact-generated tsunami wave arrives approximately Infinity hours after impact.” could use some finetuning…

What I learned(?): the asteroid Maia aka 2011GV1 in ‘The Last Policeman’ is not necessarily an extinction level or (it seems) a civilization-ending event.

True, the simulator doesn’t talk about ‘nuclear winter’ style climate effects as such… but still. Oops?

It doesn’t handle some inputs very well. I obtained results with craters 2300000 km wide, day shifts of 11000 hours (described as not significant)…

Absolutely the best app ever for a Nihilist. I created a tsunami 1950 ft high!

“Your position is beneath the continuous ejecta deposit.” Oh, that’s usually a bad thing.

Anyone else able to create a tsunami? Having more trouble than I thought one should when creating massive craters are so easy.

The Earth is completely disrupted by the impact and its debris forms a new asteroid belt orbiting the sun between Venus and Mars.
100 percent of the Earth is melted.

I may have went a wee overboard with the size, also with the velocity, possibly the density doesn’t really matter at that point.

Why not just use the closing scenes from Nuclear War, discussed earlier..

But, what if it’s made of diamond and traveling at (near) the speed of light?
