The following link will provide the ephemrides for that asteroid.

This link: http://neo.jpl.nasa.gov/orbits/
has identified 386 NEO and can provide orbits and ephemrides for
each. Click on the NEO you're interested in and then on the new page
click on the ephemrides link and it generates reams of data that is
too technical for me to decipher.

I too wonder if there is the subset of NEO that are in Earth-Mars
resonance but I have absolutely no clue what to look for.
