The color of the table row gives a rough interpretation of the severity of the threat. White or gray colors indicate a Torino scale of 0 or undefined. All other colors (green, yellow, orange, and red) represent their respective Torino scale.
Temporary designation or permanent number for this object.
Calendar date (UTC) of the potential impact.
Probability that the tabulated impact will occur. The probability computation is complex and depends on a number of assumptions that are difficult to verify. For these reasons the stated probability can easily be inaccurate by a factor of a few, and occasionally by a factor of ten or more.
Impact Energy (Mt)
Kinetic energy at impact, based upon the computed absolute magnitude and impact velocity for the particular case, and computed in accordance with the guidelines stated for the Palermo Technical Scale. Uncertainty in this value is dominated by mass uncertainty and the stated value will generally be good to within a factor of three.
Hazard rating according to the Torino impact hazard scale, based on the tabulated impact probability and impact energy. The Torino scale is defined only for potential impacts less than 100 years in the future.
