Dangerous place space isn't it
One "just missed us" earlier today!

By "just missed" I mean that it came within 140,000 miles (230,000 kilometers) which is obviously not that close, however the interesting point is that we only noticed it three days ago, so not nearly enough time for President Morgan Freeman to build a huge bunker and fill it with useful people and artifacts.
