(meteorobs) between a rock or a bolt

With the recent crash in space between the two satellites, a new source
material for "shooting stars" have become available.

To assist in sorting out natural and man made meteorids I came across a
book  that may be of interest to some:    "Space Debris:  Models and
Risk Analysis"
By Heiner Klinkrad, Published by Birkhäuser, 2006, ISBN 354025448X,
9783540254485

>From summary:
"Apart from the non-trackable objects produced by historic on-orbit
fragmentation events, several other sources of space debris will be
outlined. Models will be described to allow the generation and
propagation of the different debris families and permit the assessment
of the associated collision risk on representative target orbits for
present and future conditions. Using traffic models and possible
mitigation practices, the future evolution of the space debris
environment will be forecast. For large-size, trackable objects methods
will be described for conjunction event predictions and related risk
assessments. For hazardous re-entry objects, procedures will be outlined
to enable the prediction of re-entry times and likely impact areas, to
assess uncertainties in these factors, and to quantify the risk due to
ground impact. Models will also be described for meteoroids, which
prevail over space debris at small particle sizes."

Portions of the book can be found on google books.
