Hi everybody, In an article by Z.N.Khutorovskiy et al., 'Collisions of Space Objects on Low Orbits', published in 'Collisioons in Surrounding Space (Space Debris)', Moscow, Cosmosinform, 1995, a table is presented of five calculated dangerous encounters of space objects with the Mir space station in July 1992 through August 1994, see abridged version of the table below.

Unit of size unknown, probably meters. Object 6728 is an unidentified object in the Russian catalog, and it did encounter Mir twice. According to the article, the most dangerous encounter occured on Nov 08, 1992, at 10:18:01.2 UTC. Would anybody like to comment/check/etc.? Igor Lissov
