Re: Blow Things Up - Asteroid program - link to online program for impacts

http://www.lpl.arizona.edu/impacteffect … cteffects/

The link is to an online program that allows you to try out various scenerios involving asteroid impacts. Try it out, but be safe.  big_smile

Earth Impact Effects Program

created by: Robert Marcus, H. Jay Melosh, and Gareth Collins

This program will estimate the seismic, blast wave, and thermal effects of an impact as well as the size of the crater produced by the impact. The crater size is determined using pi-scaling.

Re: Blow Things Up - Asteroid program - link to online program for impacts

They just had a Slashdot thread about this - expect it to get slashdotted right out of existence soon.  IT's somewhat ironic that this site is about to get hit by the Internet equivelent to an extinction level asteroid...

Just for giggles, I was running the results for a 100 km diameter asteroid hitting a planet at 100 km/s.  It's pretty amusing...

Your position was inside the transient crater and ejected upon impact.

Re: Blow Things Up - Asteroid program - link to online program for impacts

Heh, exactly!  I like how the initial impact crater for that collision is about 1500 km in radius.  I also love how your curent position is buried under 30,000 feet of impact ejecta.

Incidentally, the 100 km meteor at 100 km/s is what it would take to get Venus a 24 hour day as poeple were discussing over in the terraforming section.
