- Mmmm, not necessarily. A small body striking a larger one might easily
- disrupt the larger without dispersing the pieces. No doubt someone has
- already attempted to calculate a distribution of such collisions based
- on the known distribution of asteroid sizes and orbits.
- Remember that so far these contact binaries have been observed only at
- low resolution. I'll predict that higher resolution images will show
- most of them to consist of "rubble piles", that is, many pieces of
- varied sizes, not just two big ones. (If so,
- they ought to named Barksian asteroids, after artist Carl Barks who first
- suggested the idea.) What does your theory predict?

-
- Indeed. Further bold prediction: high resolution images will show nearly
- no co-orbiting asteroids or asteroids with satellites.
-
- (By the way: is the exploded planet idea a consequence of your
- Meta Theory?)
