The Risk List is a catalogue of all objects for which a non-zero impact probability has been computed. Each entry contains details on the particular Earth approach which poses the highest risk of impact (as expressed by the Palermo Scale). It includes its date, size, velocity and probability. Impact history data can be selected in tabular and graphical form. Links to the impactor table, the physical properties and orbit visualiser are given. In most cases, the size presented in the table is estimated indirectly from the absolute magnitude, and flagged with an asterisk to denote that its uncertainty is large. When a better measurement is available in the literature, it replaces the estimated value. By default, entries are sorted by the maximum Palermo Scale value; the sorting can be changed by clicking on the table headers.
