Yes !!!!! However----- The only way that the object will come back to haunt our placid life here on earth is IF the orbital parameter dealing in TIME is precisely the same time, (or some whole number multiple), or a fraction of the earth's orbit. (The earths year and the objects year or period of rotation must be the same.) Then and only then will we need to worry but I rather doubt the orbits of any near miss objects have this particular orbital parameter. One last thought, I do not have the computer facilites to research this, but a near miss by an object with an oddball timed orbit MAY have the errors add up or subtract so that it COULD come back to haunt us, but I doubt we will be around to worry about it.
