Science Scene - Meteor Impact Simulation

Click Here to have Purdue University calculate the impacts of a meteor based on your inputs.

Asteroids and comets come in all shapes and sizes—from small pebbles, to larger SUV-sized fragments, to massive asteroids like Ceres, which has a diameter of about 621 miles (shown in picture). Much of the asteroid material that crosses paths with the Earth burns up when it enters the atmosphere. About once every 100 years, though, a fairly large asteroid strikes the Earth.
But how big does an asteroid need to be to cause major destruction? The new “Impact: Earth!”asteroid impact effects calculator will help you find out. The interactive web tool, developed by a Purdue University research team led by Jay Melosh, allows anyone to calculate the potential damage caused by a comet or asteroid striking the Earth. Users input information into several parameter fields, such as the diameter and density of the object, its angle of entry, and the location where it will hit. The calculator then estimates the impact consequences, providing information about debris distribution, ground shaking, size of the resulting crater, and whether a tsunami will be generated.

  1. And I think compasses react wildly around those craters because of the magnetic content of the meteors -- or maybe that's just something I saw in a movie.
