There is currently no technology on Earth that could stop a massive asteroid from wiping out Europe, according to a simulations carried out by leading space agencies. The week-long exercise led by Nasa concluded that catastrophe would be unavoidable, even given six months to prepare.
The hypothetical impact scenario, which took place during a planetary defense conference hosted by the United Nations, proved that governments are woefully unprepared for this kind of disaster.
If confronted with the scenario in real life, we would not be able to launch any spacecraft on such short notice with current capabilities, the participants said. The only response to such an event would be to evacuate the area before the asteroid hit, however the impact zone was across large parts of North Africa and Europe.
Nasa is currently tracking roughly 25,000 NEOs (near-Earth objects) and new discoveries are being added at a rate of around 30 each week.

We had such a passage about 70,000 years ago. Comets should arrive in about two million years.
Now what about passages that happened before? We might not be so sure about that especially if it was a planet instead of a star. We can see bombardments on the moon from prior events.
