Col Beausabre: I don’t know this for sure, but I think getting there is not straightforward, and will take a lot of time. Moreover, Hayabusa-2 has ion engines, which while very efficient have a very tiny impulse. They can change the planned path only very very slowly.

Once every three and a half years for a close approach is actually the opposite of rare.
