Multiple potential impact corridors of 69 asteroids are shown to visualise the international nature of the impact hazard as every nation could be affected by a future impact. The colour indicates local impact probability as powers of 10. The corridors in this figure correspond to extremely unlikely impact events where a colour reading of -10 represents a probability of one in ten billion and, thus, no significant threat.
