It's only 800 feet across. No big deal I guess, but it's passing really close. They don't say it, but in the past, asteroids and comets get caught in the gravitational field when they pass by a planet. Like Hale Bopp did, but that was Jupiter, a much larger planet.
I think a rock the size of a football stadium could do some serious damage if it held together on the way in. Forget global warming, the sky is falling! Panic about this!
