>>> let's give each other a pat on the back. we made it. a short time ago an asteroid passed by the earth trailed by its own moon at a distance from us of about 3.6 million miles . had it gone differently it would have left a mark. it's about 2,000 feet wide, roughly nine times the size of an ocean liner . it's traveling at a high rate of speed.
