Vil en asteroide ramme os i 2036?
Det tror jeg ikke.

Didn't I just state in a previous answer that is the next doomsday "event" after the Mayan calendar failure of 12/21/2012? The 2036 event is based on whether or not the asteroid passes through a keyhole (the right spot in space) on a near-miss (20,000 miles) in April 2029... see
http://en.wikipedia.org/wiki/99942_Apophis
Even in the unlikely chance (one in a hundred) that Apophis does eventually strike the Earth, it's only about 1000 feet in diameter, far short of the 6 mile or greater size for near-worldwide extinction like the dinosaur strike 65 million years ago. Plus the odds are for a water strike, thus creating a tsunami that would rival the world's worst past tsunami's. But certainly not a concern for a mass extinction. That size, if land were involved, would knock out a state or two (USA) or a couple of European countries, if average speed is involved. The velocity is the key component, remembering that your kinetic energy formula is energy = 1/2 mv squared, (velocity squared).
Information based on future observations, NASA will decide whether or not to send a transponder to that asteroid in the future, so they can accurately track it... we'll know more about the orbit of Apophis after a relatively closer approach I believe in 2013 or 2014. It's something we should keep track of, but I wouldn't lose any sleep over it.

Mayan kalender eller ej, ingen kender dagen, står der i bibelen, ikke engang Jesus, kun Faderen. Det er hvad vi har at forholde os til. Og heldigvis. Gider ikke ryste i bukserne fra nu af og til 2012 fordi Mayanere har givet os en skrækindgydende dato.
Den kan komme i morgen
For få år siden var der en mindre men kraftig sværm der eksploderede over store områder af Jupiter.....det kom totalt bag på forskerne, de har nu ellers rimeligt tjek på det.
