I just don't see why the press is freaking out about asteroid 2006QV89. The 2006 in its name means it was found in the year 2006. See pix.
The NASA Sentry (automated collision monitoring system) website doesn't even list 2006QV89. Go to website and search for 2006 - only six asteroids found in 2006 are listed and none is 2006QV89 or 2006 QV89. Website table is sorted by the Palermo Scale that rates technical impact hazard.

------------------------
The International Astronomical Union Minor Planet Center website shows Potentially Hazardous Asteroids (PHAs) as of 2017 (so the 2006 one surely fell within the time range of consideration) but 2006QV89 is not on the list. Go to website to see the whole table, which is sorted by distance from Earth (2006QV89 is predicted to pass Earth at a disance of 0.04587 AU or 6,861,695 km.
