Apophis is due to pass by earth and then be on its way around the sun in 2029/2030. It will come back in 2036 and is expected to plummet into the Pacific Ocean. Hawaii will be a devastating loss along with extensive damage to the west coast of the United States.

So says Neil deGrass Tyson in his book;

- Death by Black Hole; pages 261-262

Supposedly, everybody who knows something about this isn't saying much. o_O

Last time I checked, there was a 1 in X chance ("X" being a very large number) that Apophis would pass though the necessary "key hole" that would alter it's path in such a way that it would impact Earth on a later pass.

What concerns me most is not the thousands or tens of thousands of known objects (do you know how many NEOs there are?) but those we do not know about. Many of these are of low albedo and, when coming 'out of the Sun' stand zero chance of being seen in time. I remember around 1992 or 1994 (IIRC) there was one close miss, then the same day there was a total unknown (out of the Sun) which was not seen until it had passed us.

After the Late Heavy Bombardment we feel, rightly or wrongly, that we are comparatively secure from Theia size impact. However, there are extreme numbers of asteroids and comets (and the new category of in-betweens) in the outer Solar System. If large numbers of these were dislodged there is a remote possibility of impact eventually. Beyond a certain size there is nothing we can do to guard against catastrophic impact.

And this:
"alter it's path in such a way that it would impact Earth on a later pass."
can happen to the ones we 'know to be safe'.
