Science Channel had a 2 hour season premier of How the Universe Works that was dedicated to asteroid strike and went in depth too.
They had a nice animation of a smaller one taking out New York and then started talking about Apopohis and how it was much, much larger and due to
pass on a very close trajectory in 2029 (?) I think. My only quibble was that there animation of the smaller rock showed them losing the entire city
of New York, and then when the obligatory talking head went on to talk about how much larger the devastation of Apophis might be, his big talking
point was "You'd lose the whole city!" as though we hadn't already been shown that from a smaller rock.
The key takeaway there was to listen for the size of the Krakatoa blast. Krakatoa affected the entire world's climate, but should Apophis impact, it
will do so with twice the energy and destructive power of Krakatoa.
