Articles and discussion about Asteroids.
Asteroids are small rocky, metallic, or icy bodies that orbit around the Solar System. Larger asteroids have also been called planetoids, and those with a tail are referred to as comets.
Asteroids have collided with the major planets before in the past, releasing huge quantities of energy, leaving craters and devastation in their wake. However, most asteroids orbit far from any planet on relatively stable orbits. Asteroid mining has been proposed as a future industry - if successful, a huge wealth of minerals and resources could be within our grasp.

Diagram showing how the impact of an asteroid or meteorite works.
So I thought this was a cool-looking set of pictures that show the different stages of an asteroid or meteorite impact like of course now it first lands from Space and hits the solid surface of a planet or moon and what not as it is very fascinating stuff. Enjoy!

How far away can debris from an asteroid impact reach?
I know this question has a ton of variables from the size of the meteor, it's speed, trajectory, impact site, etc.
But do we have an understanding of how far a piece of rock can be flung away from the site of an impact center from an asteroid?
