How do they know the future trajectories of future objects that are hit by other future objects at some point and both have their future trajectories changed.
Thats the fly in the ointment. The one in Russia on February 15. 2013 hit the same day that another we knew about passed around 17000 miles from the Earths surface. We knew that one was coming close. We didnt even know that other one existed until there was 440 kiloton explosion above Chelyabinsk, Russia.
The same way that politicalscumbags know what is BEST FOR US CITIZENS.
They are Psycho, I mean Psycic, Oh hell I mean CRAZY!!!

Just feed the data into the climate change models, they can predict anything accurately....Duh!
They consult meteorologists!
