Care to recheck that one? I always thought that the lowest point in
an orbit was perigee.

I think there are probably times when the closest point on earth to
the moon might be Mauna Kea (coincidentally, site of a huge observatory
complex). Mauna Kea, Hawaii, mid-Pacific. Think about it.

So you caught my deliberate mistake :-)

That rather depends on whether perigee is in the Northern or Southern
hemisphere. Think about it. |

Man, I only got as far as thinking that Everest could equally likely
be the farthest you could get from the Moon by walking.
Sounds more likely that the Moon will come to Mohammed. |

I didn't mean YOU should think about it, that would clearly be an
impossibility. |

The moon's orbit precesses fast, with a period of only about 19
years. If, at some time, perigee occurs as far north as possible,
than about 9.5 years later it will happen as far south as possible.
So anywhere on the earth's surface beween about +/- 28.5
degrees latitude can be directly below the moon at perigee.
What point on the earth's surface is furthest from its centre?
It's bound ot be fairly close to the equator. That point will be
the one that comes closest to the moon 's centre.
Does the topography of the moon's surface matter? I'm
not sure...

I don't have the Guiness Book at hand, but I seem to recall that it
says the farthest point from the Earth's center is Chimborazo
(20,561'/6,265m), in Ecuador.

Androcles, you're right. Please don't hurt me with your awesomeness, I give
in. You've made it so that I can only reply to alt.morons, thank you, I
deserved that. Please, if you think of any more clever turns, by all means,
feel free to censor my opinions, because you deserve better.
Sincerely, Dwight |

Definitely not a high-value target, too bad.

Hey, don't give up on the guy too quick.
First a deliberate mistake, then deliberate provocation; I was afraid
that a pun was coming next.
If he gets to that place closest to the Moon, I bet he'd let me stand
on his shoulders to prove that you can get still closer to the Moon by
walking. |

Well no, this has no importance at all. All we'd done is proven
Sir Ranulph Fiennes ascent of Everest and his claim "This is the
closest you can get to the moon by walking" has no real basis in
geometry, there are many places you could walk to that are
closest to the moon at the time you take a stroll up a mountain.
The moon will be where it will be and if Everest is facing away
from the Moon then Sir Ranulph Fiennes is FURTHEST from
the Moon (which he will be 12 hours later as the Earth turns).
Not 12 hours, not unless Everest is on the equator, which it isn't.
But there will be a time, when the latitude of the sub-lunar point is
roughly equal and opposite to that of Everest, when the peak of
Everest is the most distant point on the earth from the moon .

I don't think it was deliberate, he's a meglomaniac like MV of
rec.backcountry fame. If he proves smart enough to be dangerous, maybe, I'll
change my mind.

You know, I was kinda getting into the thread until Mr. Munn Mann went off
the deep end...
Takes all kinds I guess.
