Of course. There is not nearly as much funding into watching for these as there needs to be. Moving them off course requires knowing far in advance. I would be more concerned about Apophis [1] for known objects. It's orbit may be tugged on by earth on the next pass, increasing chances of impact 2 passes from now.
