This item is an interactive tool that calculates the crater depth and energy released when an asteroid or comet collides with a planet. Users can choose to bombard any planet in our solar system, and may also set the diameter, composition, and velocity of the impacting object. This resource was designed to help students understand the relationship between mass and momentum, and how a planet's atmosphere helps protect it from bombardment.

This item is part of a larger collection of animations, simulations, and interactive tools for astronomy students.  SEE RELATED MATERIALS on this page for a link to the full collection.

4. The Physical Setting

4A. The Universe
  • 6-8: 4A/M4. Many chunks of rock orbit the sun. Those that meet the earth glow and disintegrate from friction as they plunge through the atmosphere—and sometimes impact the ground. Other chunks of rock mixed with ice have long, off-center orbits that carry them close to the sun, where the sun's radiation (of light and particles) boils off frozen materials from their surfaces and pushes it into a long, illuminated tail.

AAAS Benchmark Alignments (1993 Version)


B. Mathematics, Science, and Technology
  • 2B (9-12) #1.  Mathematical modeling aids in technological design by simulating how a proposed system would theoretically behave.
