Asteroid 2004 BL86 Poised for Earth Fly-By

In what seems to be a neverending stream of these,  NASA has once again announced that an asteroid is going to make a too close for comfort fly-by of planet Earth on Monday.  While this asteroid is one of the closest yet,  NASA contends that it is no threat to the Earth in any way despite it being so close it will be observable by small telescopes.  As usual, there plenty of people in conspiracy circles who disagree with this assessment.
