2013 refinement The close approach in 2029 will substantially alter the object's orbit, making predictions uncertain without more data. "If we get radar ranging in 2013 [the next good opportunity], we should be able to predict the location of 2004 MN4 out to at least 2070." said Jon Giorgini of JPL. Apophis will pass within 0.0966 AU (14,450,000 km; 8,980,000 mi) of the Earth in 2013, allowing astronomers to refine the trajectory for future close passes. Just after the close approach on 9 January 2013, the asteroid should peak at about apparent magnitude 15.7, On January 31, 2011, astronomers took the first new images of Apophis in more than 3 years.

google space engine. It's a free game that's mind blowing and really show's you how big space is.Honestly no offence meant, but seriously you have no idea until you try space ship mode and see how long it takes to get to the point where you can see the entire earth, and the distance is less than 0.001 AU.

1 LD = Lunar Distance = 238,606 mi
Distance of Moon from Earth = 238,900 mi
Meteorite 2012 KP24 is: 0.1 Lunar Distance = 23,862 mi
About 1/10th distance to the moon.
Low Earth orbit: Geocentric orbits ranging in altitude from 0–1240 mi
International Space Station, Hubble
Medium Earth orbit: Geocentric orbits ranging in altitude from 1,200 mi to about 22,236 mi
Communications satellites, GPS
High Earth orbit: Geocentric orbits above the altitude of about 22,236 mi

It will only be a threat if EXISTING advanced techs do not eliminate it. In the future n a few more years these techs will be even more advanced, so if a threat makes it thru related to asteriod/comet impact then it may be due to stragetic forcing of the celestial object evading advanced asteriod/comet defense tech or it may not even be a asteriod/comet at all???
