I'm replying late enough that additional observations have already significantly reduced the inferred probability of a collision. QQ47 is now downgraded to a Torino Scale of zero.
Still, I couldn't help noting that the period is 1.14 years. Isn't that suggestive of an 8:7 resonance? That is, when an asteriod clearly intercepts the orbit of a planet, it is possible that they haven't collided yet because a stable resonance exists.
These resonances can be weird and wonderful. Looking at the orbit, this one would be fairly ordinary, except that resonances are usualy small integer ratios like 3:2 or 4:3.
