Asteroid hit overdue? Well, technically our little corner of space isn't all that 'active' anymore; things settle down as time goes by. So theoretically the chance of Earth being nuked gets smaller every day. That's my logic speaking anyway.
Now there are still plenty of asteroids in the Kuiper Belt ofcourse, of which some might be flung our way, and rogue asteroids cruisin' through space. But we're a small target in the vastness of space, so I don't think we'd need to worry that much.
(Well, ofcourse I don't think we'd need to worry about it anyway, it's not that we can do anything about it.
