Hello. Just arrived here, saw a question in phys.org feeds and thought I could help a bit with it. I already like it here.

In real life, similar events have happened - An example is the 2009 iridium 33 / cosmos 2251 collision over the Siberia. https://en.wikipedia.org/wiki/2009_satellite_collision Their velocities were at the order of 7.5 km/s (altitude 780km,or 480 miles) and their relative velocity nearly 1.4...
