The concept of a near-Earth object (NEO) impact projection metric (PM) based on the ratio of the observation time to the impact time, rho(t), for a projected NEO impact is developed. The PM can assist NEO mitigation decision-making that is based on the discontinuously changing cumulative impact probability and help mitigate false alarms of NEO impact with Earth that have undermined public perception toward the veracity of predicting NEO threats.
