Asteroids on the Impact Risk List Above a Probability Threshold (NASA JPL Sentry)

jplssd/sentry-risk-list

The asteroids currently on the JPL Sentry impact-monitoring list whose cumulative impact probability is at least a threshold you set, most probable first: for each the designation and full name, cumulative impact probability, Palermo scale cumulative and maximum, Torino scale maximum, number of potential impacts, the span of possible impact years, diameter in km, absolute magnitude, velocity at infinity and the last observation date. At most 100 objects are returned (total says how many matched). Optionally keep only objects brighter than an absolute magnitude H. Probabilities are small by nature; a Torino 0 means no unusual concern. NASA/JPL Solar System Dynamics data, served by Eden Engine; not an official NASA or JPL product.
