Look. Do a google search on 'au in miles' and google will provide a number of 93 million miles.
Then do a search on 'nasa au' and you'll find that Nasa's website gives a number of 93 million miles.
I didn't say 100 times, I said 40, and I stand by that statement.
I don't think it was close enough to be a concern. I know that with the advent of accurate astrological equipment, people realize that there is a lot of things out there whirling around like mad. I do not think that we should be scared by this in any way. We do know that large objects can hit the earth, but it's not like this happens often.
