|Title:||Natural Hazards-Catastrophic Collisions|
|Abstract:||Despite our Earth-bound perceptions, our home planet is but an insignificant speck in space. It is fragile and vulnerable to hits from asteroids or space rocks on a collision course. Asteroids range in size from those like Ceres with a diameter of ~1000 km to those the size of sand grains.|
