asteroid

[woolley]

Why didn't anyone see the asteroid that came close to the Earth a couple of weeks ago?

[incitatus]

Because it was very small and dark, against a big dark background.

[6,000 Miles]

The answer is that it came from the direction of the sun and thereby got noticed only very late. I would advise to look here for more info: http://story.news.yahoo.com/news?tmpl=story&u=/spa
