He is, yes.
It really depends - there is a wide variety of history in our galaxy with any number of threats. It doesn't seem that anything larger than a person has been brought here at this point so it seems unlikely that we'd get entire ships, but it isn't impossible. Imperial ships are certainly going to be the most likely to be a threat from our era. That or the Yuuzhan Vong... They'd be a great threat to this planet.
