I guess the probability of impact won't reach the >50% level until a few months before impact due to variations in earth's orbit and by that point the ability to do anything about it is limited.
- pfdietz 2y ago> due to variations in earth's orbit I don't see how this could possibly be correct. Earth's orbit is very precisely known.
- hermitcrab 2y agoI think the uncertainties are down to not precisely knowing: -the size of the object -the orbit of the object -the velocity of the object -effect of outgassing and solar wind on the object (as mentioned in the top comment) Rather than uncertainties in the earth's orbit.
