Earth Four Hours From Destruction!

Ok, not really.
On the evening of Wednesday November 5, 2008 (for most of North America) a giant rocky body will pass through Earth's position in space less than 4 hours after Earth was there. If Earth were 3 hours and 40 minutes farther back in its orbit at that time, the collision would wipe out all life on Earth. In fact, it would render Earth's surface uninhabitable for millions of years.

Should the tabloids media run headlines like "Earth 4 Hours from Destruction"?

No, because there's a catch to this story. It's revealed by the question "What will the rocky body look like in our skies on the "eve of (near) destruction?" The answer is that the object will appear as bright as a first-quarter Moon. For a good reason — the object is the first-quarter Moon.
