NEO Uncertainty Graph help needed.

Okay, I was looking across the net and found a NEO pegged as potentially dangerous. I was able to get hold of the uncertainty map.

This is it...


Now i'm not astronomically savvy but when people start discussing this as a "sudden approach" and "came into the light unexpectedly" i begin to worry.

Put me at ease folks

If you're serious and want full details of the NEO then u2u me and i'll provide you with it.
