Top: collisional probabilities of LL-like NEOs originating from the Flora family and their temporal distribution. Individual bodies (out of 1900) are distinguished by shades of gray. The vertical range shows both low and high probabilities. For comparison, the horizontal lines indicate the mean probability p of all NEOs (orange), short-term initial probability p′ of Apophis (cyan), long-term probability p″ of Apophis (green). Bottom: Distribution of all p values (gray) and of the maximum p value (black).
