Outer Space Stuff

Distance from Impact: 3.22 km.
Projectile diameter: 9.14 meters.
Projectile Density: 3000 kg/m.
Impact Velocity: 25.80 km per second.


The projectile begins to breakup at an altitude of 60,700 meters.
The projectile bursts into a cloud of fragments at an altitude of 33,500 meters.

The air blast will arrive approximately 1.7 minutes after impact.
Sound Intensity: 21 dB (Easily Heard).


The Earth is not strongly disturbed by the impact and loses negligible mass.
The impact does not shift the Earth's orbit noticeably.

These are just a few of the calculated results of an impact that I created using the Earth Impact Effects Program. If it sounds complicated, don't worry, it's not. The website form is both easy to understand and to use, requiring very few inputs and having built-in presets to assist you in creating an impact scenario.

From the actual website:

Welcome to the Earth Impact Effects Program: an easy-to-use, interactive web site for estimating the regional environmental consequences of an impact on Earth. This program will estimate the ejecta distribution, ground shaking, atmospheric blast wave, and thermal effects of an impact as well as the size of the crater produced.

Please enter values in the boxes below to describe your impact event of choice and your distance away. Then click "Calculate Effects" to learn about the environmental consequences.
