Hello,
Given the recent close conjunction between Compass-1 and Sich 1, I was curious how common such encounters were. Using SOCRATES on the celestrak site, http://celestrak.com/SOCRATES/, it looks like they are fairly common.
Here are some up coming conjunctions:
Objects Date Time UTC Distance KM
AO-51 (28375) & Cosmos 676 (07433) 27 Jan. 2010 09:05:36 1.93
Hope-1 (36122) & Cosmos 272 (03818) 30 Jan. 2010 15:07:21 0.511
Hamsat (28650) & TIROS 8 Deb. (19396) 1 Feb. 2010 01:26:28 0.926

Take those forecasts with a grain of salt since they are based on TLE's with limited accuracy. On the day Iridium 33 and Cosmos 2251 collided, SOCRATES forecast a couple other conjunctions closer. SOCRATES predicted a miss of 584 m.
Fortunately for us, there is a lot of space in space.

Sort of like walking 1000 paces, turning, and firing...not much danger of anyone perishing in such a duel? Better yet try to hit the other's bullet. The most amazing is that two orbiting satellites actually collided.
