Not that close; check out the Close Approaches list on the NeoDys page
(linked from the one Ian gave). Occasionally it gets as close as 0.04AU
or so (that's about 6Mkm), but not that often. Note that the Java applet
on the JPL page comes with a warning notice that specifically tells you
not to use it for encounter prediction!

Not so good, alas. Notice that its orbit is inclined at about 11deg.
That means it passes through the ecliptic with a "vertical" velocity
of 5-6km/s, however low its relative "horizontal" velocity might be.
