0.00160 AU. An AU is the distance from the Sun to the Earth, or 93 million miles. By my calculations, 0.00160 AU is about 150,000 miles. Close but not too close.
Ah, misread the article, the .00016 AU is closest approch to the moon. It will stay over 200K miles away from the Earth.
The average distance between the Earth and Moon is 238,857 miles.
So .85 lunar distance would equal approximately 203,028 miles.
