Notes. Table columns: calendar date (year, month, and day) for the potential impact for asteroid 2011 MD, approximate σ value of the virtual impactor location along the LOV, minimum distance (the lateral distance from the LOV to the center of the Earth on the TP confidence region), stretching (how much the confidence region at the epoch has been stretched by the time of impact), probability of Earth impact (IP), and Palermo Scale (PS). The width of the TP confidence region is always few kilometre, thus not reported.
