This site lets you play with some variables involving the impact of any size asteroid or comet hitting the earth. Some of the variables you get to enter are; size of asteroid, density of asteroid, angle of impact, composition of asteroid, and your distance from the impact.

 

 

 

 

 

 

 

Once you enter these variables, the calculator gives a really detailed on how it will effect the area you put in, and basically the earth. REALLY COOL!

 

 

 

 

 

 

 

One I put in was a 5.3 mile crater hitting South Carolina, about 2,000 miles away from me, here are just some of the things it gave back:

 

 

 

 

 

 

 

Energy before atmospheric entry: 2.03 x 1023 Joules = 4.85 x 107 MegaTons TNT

 

 

 

 

 

 

 

Final Crater Diameter: 109 km = 67.6 miles

 

 

 

Final Crater Depth: 1.21 km = 0.754 miles

 

 

 

 

 

 

 

The fireball is below the horizon. There is no direct thermal radiation.

 

 

 

 

 

 

 

The major seismic shaking will arrive at approximately 644 seconds.(Felt indoors by many, outdoors by few during the day. At night, some awakened. Dishes, windows, doors disturbed; walls make cracking sound. Sensation like heavy truck striking building. Standing motor cars rocked noticeably.)

 

 

 

 

 

 

 

The ejecta will arrive approximately 1080 seconds after the impact.

 

 

 

At your position the ejecta arrives in scattered fragments

 

 

 

Average Ejecta Thickness: 4.24 mm = 0.167 inches

 

 

 

 

 

 

 

The air blast will arrive at approximately 9760 seconds.i

 

 

 

Max wind velocity: 23.7 m/s = 53 mph

 

 

 

Sound Intensity: 80 dB (Loud as heavy traffic)

Major Global Changes:

 

 

 

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

 

 

 

 

 

 

 

oops

the earth would be completely annihilated if a meteorite that size careened into the earth... i like burritos............
