The Risk List is a catalogue of all objects for which a non-zero impact probability has been detected. Each entry contains details on the highest-probability impact event for the specific object, including its date, time and probability. In most cases, the size presented in the table is estimated indirectly from the absolute magnitude, and flagged with an asterisk to denote its large uncertainty. When a better measurement is available in the literature, it replaces the estimated value.
