Glad someone is out there standing guard..
My question is this.. Whilst you are 'watching our backs, If it all goes pair shaped, what are you going to do to protect us from a 770m asteroid? Got some superman abilities that your not telling us about hmm??
All seriousness though, its a good image.. The asteroid sure traveled a long way in the field of view.. Any ideas of what its made of? Surely NASA have some idea, but whether or not its public is another thing..
