0 one of several very small planets that move around the sun -- asteroid
Asteroids sometimes collide with each other.
In the former case, comets are rocky asteroids surrounded by a debris cloud.
Other discoveries have led to the conclusion that several percent of all asteroids have satellites large enough to be discovered remotely.
The jumps take place in an apparently chaotic fashion and lead to random walks across the asteroid belt.
In addition, it is smack in the middle of a mineral-rich asteroid path, and has already benefited from many mineral-rich asteroids.
In these cases, the nonhuman comes in the form of a rogue comet or asteroid, shattering the stability of the human world.
These would be easy to identify because of their tangential touchdown onto the asteroid, resulting in considerable rolling from their orbital momentum.
Imagine that you are traveling in a spaceship and have learned that there is a mineral-rich asteroid heading your way.
Impacts by comets and asteroids with rocky planets are known to displace large masses of material.
