Future Moon Orbital Questions
So imagine my surprise the other night to be "channel surfing while intoxicated" through what seem to be hundreds of channels I didn't know I had, only to see the Bad Astronomer's face go blipping by! It was the only reason I stopped! I figured somebody was going to take him out of context to prove mermaids can't be found because they're all hiding from the megladons, as predicted by the second coming of Niburu.
(That fact that that sentence can be parsed out on a science board, even in jest, should be a forever stain on the Discovery Channel...)
Back tracking a few clicks I chance upon a science channel I didn't know existed and it doesn't make me cringe ever ten minutes! Who knew!
But to my point.
As the moon coasts inward billions of years from now, the inner Hill sphere limit seems to be 11,000 miles before lunar break-up. The questions I have are thus.
Is that inner orbit accurate?
And more importantly...
Who can tell me how fast the Moon's orbit would be prior to destruction? An average of the last couple of thousand years would be close enough.
Who much sky would the Moon take up that close?
Also any input whatsoever about the tides would be welcome. Ever question I try to form just sort of sticks when I try to imagine the Moon that close and presumably "that fast".
I'll even entertain the possibility of lunar induced tide tracks carved through whatever continents exist at that time.
