This is your life, and it’s ending one minute at a time.
The asteroid has been given a 0.06 on the Palermo technical scale,
PS = log10 [PI / (fB × DT)]
where PI is the impact probability of the event in question and DT is the time until the potential event, measured in years. The annual background impact frequency,
fB = 0.03 × E-4/5
is the annual probability of an impact event with energy (E, in
megatons of TNT) at least as large as the event in question.
Several new images have been added into the rotating header image pool. Reloading this page several times should present a nice sampling. The rotation is accomplished using the Hivelogic Image Rotator.
