Isn't it Rosetta (not-a-stone)?
2007 VN84 (H=26.3) had a close encounter with Mars in the last decade
of February this year.
Compare the dates and distances with those of Rosetta spacecraft
(http://www.esa.int/esaCP/SEMC20VOM8F_index_1.html):
Closest approach will take place on 13 November 2007 at 21:57 CET, at
which time Rosetta will speed past at 45 000 km/h (about 12.5 km/s)
relative to Earth. At this time, Rosetta will be 5301km above the
Pacific Ocean, south-west of Chile, at 63° 46' south and 74° 35' west.
