        2001 PM9 <= May 10, 2003 vs ZETATALK May 15, 2003

        It will make a relatively CLOSE PASS to within .089AU on
        MAY 10, 2003. The first possible impact date calculated
        and the one with the highest probability of occurring is
        set for June 17, 2005. If it misses Earth on that pass there
        are another 28 possible impact dates calculated between
        2005 and 2079. The orbit simulator is interesting
        (http://neo.jpl.nasa.gov/cgi-bin/db?) On June 3, 2003 we
        will be in the area of the solar system where 2001PM9
        was 10 days before.  .... This plot simulator
        (http://newton.dm.unipi.it/cgi-bin/neodys/neoibo?) places
        2001PM9 closest to Earth in between April 7 and
        April 11 2003.
