Abstract
Bennu's Earth close approaches are deterministic over the interval 1654-2135, beyond which the predictions are statistical in nature. In particular, the 2135 close approach is likely within the lunar distance and leads to strong scattering and numerous potential impacts in subsequent years, from 2175 to 2196. The highest individual impact probability is 9.5Ã10-5 in 2196, and the cumulative impact probability is 3.7Ã10-4, leading to a cumulative Palermo Scale of â1.70.
