Caption
One of the keyhole probability maps of the asteroid Bennu, The crosshair corresponds to the location on the surface that minimises the asteroid impact hazard after deflection. The maps assume a 25-metre targeting uncertainty for a kinetic impactor mission. As a result, deflection sites that could result in the kinetic impactor missing as a result of this uncertainty are not considered and form a grey boundary around the targetable region of the asteroid.
