A Venus-crosser asteroid is an asteroid whose orbit crosses that of Venus. The known numbered Venus-crossers and outer-grazers (marked †) are listed below (Mercury-crossers or grazers are marked ‡).
Venus also has a quasi-satellite, 2002 VE68. This asteroid is also a Mercury- and Earth-crosser; it seems to have been a "companion" to Venus for the last 7000 years or so only, and is destined to be ejected from this orbital arrangement about 500 years from now[1] (http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=2004MNRAS.351L..63M&db_key=AST&high=40daf3f6f900097).
Note: All of these are also Earth-crossers or grazers.
