Seriously, this is a hyped article.
The current Torino Scale rating and classification on Palermo risk places this in the category defined by NAEO as:
A routine discovery in which a pass near the Earth is predicted that poses no unusual level of danger. Current calculations show the chance of collision is extremely unlikely with no cause for public attention or public concern. New telescopic observations very likely will lead to re-assignment to Level 0.or as NEO explains when giving the probability of any impact0.018000000% chance of Earth impact
or
1 in 5,560 chance
or
99.98200000% chance the asteroid will miss the Earth
or
1 in 5,560 chance
or
99.98200000% chance the asteroid will miss the Earth
But that takes the fun out of watching all of the idiots running around, screaming "The sky is falling!!! The sky is falling!!!"
Sure. That's what they want you to believe.
Have a nice day! :-)
