How about Near Earth Objects?

They are the stuff of disaster movies like Meteor, Armageddon and Deep Impact. It is believed that a NEO caused a mass extinction at the end of the Cretatious, yet from what I heard the number of people scanning the skies for these is equivallent to the crew compliment of your local MacDonalds.

Perhaps we could have a discussion about how likely these things will hit us and if one were on course for Earth, how much warning would we get and what we could do.
