NASA has doubled its estimate of the number of killer space rocks following orbits closely aligned with Earth’s in a paper accepted for publication in the Astrophysical Journal.

It says there are now believed to be about 4700 potentially hazardous asteroids (PHAs) sharing the space near our planet, which it defines as having diameters at least 100 metres.

    If it was determined that Apophis was going to hit in 2053, there is absolutely no chance of effective action to deflect it, even if it were technically feasible. International conferences held to come up with an action plan will be taken up with arguments about who’s going to pay for it, with everyone arguing why it should be someone else. Any democratic government that took some responsibility would be turfed out in an election campaign about a ‘great new asteroid tax’ or something along those lines. Meanwhile the Heartland institute, the IPA and similar organisations will set out to convince people that the asteroid doesn’t exist or if it does it won’t hit and anyway its all a leftist plot to institute one world government. Others will say the asteroid is ‘weightless, colourless and odourless’ and therefore couldn’t possibly be a problem.
