As of a month ago when I last updated my spreadsheet from the IAU Minor
Planet Center, there were 7 NEOs of absolute magnitude H>(:
1991 VG
2000 LG6
1991 TU
1994 ES1
1994 XM1
1991 BA
1993 KA2.
Read http://cfa-www.harvard.edu/iau/lists/Sizes.html to see how to convert
from absolute magnitude to diameter, and the uncertainties in that
conversion. All these NEOs should be less than 12 meters in diameter.
Some could potentially be less than 1 meter in diameter.
Based on my very rudimentary knowledge of orbital mechanics, the order in
which I've listed these NEOs should roughly correspond to the ease of
reaching them, with 1991 VG being the easiest. Perhaps Al Globus could
opine on why he mentioned 1991 BA in his AsterAnts article (c.f.,
http://www.nas.nasa.gov/~globus/papers/AsterAnts/paper.html ), but he did
not mention 1991 VG, although presumably both were known at the time of
writing.

Perhaps we need one that brings back a baby asteroid to the ISS. That would be something. Does anyone know of a candidate asteroid?
