      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.
