Rusty's AAOA (and NEO Size-Frequency Diagram by Alan Harris)

Here is Rusty's Alternative Analysis of Alternatives from the B612 Foundation website. I also show below the size-frequency diagram for near-Earth objects by Alan Harris that is in Rusty's report.

Size-frequency diagram for near-Earth objects, courtesy Alan Harris. The superposed intersecting lines bound the 99% of NEO impacts most likely to be encountered and trigger a call for deflection. These NEOs range from 45 – 400 meters in diameter. The left vertical line reflects the most recent estimate of the impact energy (5 MT) associated with the Tunguska event in 1908.
