There's a giant asteroid that's going to be passing very near the Earth, but don't be alarmed. You'll be fine.
A very large asteroid will pass very close to the Earth on Friday, but it's nothing to worry about. It's only close in astronomical terms, and poses no threat to our planet. So what's all the fuss about? The asteroid, dubbed 1998 QE2, will be a prime target for radar telescopes to study. Those of us with non-radar telescopes might be lucky enough to catch a dim glimpse.
