    Somebody check my math, but I have that as 15 minutes, 17 seconds of earth orbit...that's pretty close.

    NASA say it will fly within the satellite orbit range, but it is not a prob.

    If they say that, I'm happy enough.

    I'm just saying - on astronomical scales, that's not even a whisker.

    How about if it hits a satellite?

    A large one?

    Exceedingly improbable.

    I think Mikelom is trying to ascertain what kind of weapon would be
    powerful enough to dislodge such a rock. Would a big gun be accurate
    enough? or would you have to employ some kind of drilling device to split
    it in two?

    Wikipedia gives the earths orbital speed as 29.7 km/s and 17 miles is about 27 km thats a bit under 1000s which is about 17 minutes. So allowing for the 10% error in my 1000s I think you got your maths right.

    But unless the thing gets trapped by the atmosphere it really doesn't matter how close it gets. The Earth has a diameter of 12,600 km so it's 2 and a bit times the diameter of the earth away. Which means we shouldn't get a problem even if it hits a satellite. If it does hit a satellite then the satellite's had it, but it won't affect us other than losing the satellite. Could be spectacular to watch though.
