I wouldn't be concerned about either. The probablility of impact for Apophis in 2029 is nil. Same for XP-14. Why should anyone be concerned about something we know absolutely for sure, won't happen? If you want to worry about something look up the NEO page at JPL, find an asteriod which has a positive probability for impact for a relatively near time and be concerned about that one Actually Apophis for 2036 may be a good guess. BTW Apophis is 2029 won't be too big a hazard for satelites. Even if we didn't know it was there the chance of random impact with a satelite is tiny, much smaller than meeting a piece of space junk.

Which brings me to my answer on what I'm worried about. I'm not worried about any of the NEOs we've found. It seems neither is a substantial hazard and in any case we should have an advance warning if one of them were to hit. I'm worried about the ones we haven't found yet. Especially the ones which are mostly within Earth's orbit becouse they are next to impossible to find from the ground. Those are the real danger becouse a large one could hit without us knowing anything about it beforehand.
