Question on moon?

Question

Before the Earth's last ice age has the orbit of the moon changed?

Sorry should have said since instead of before but another question slipped into question.

Answer 1

No, there is no reason for the ice age to affect the orbit of the moon. Even though conditions on the earth's surface changed drastically, the earth was still the same mass as it is now, so there was no gravitational change.

EDIT:
Sorry, I misread your question. I though you asked if the orbit changed BECAUSE of the ice age.

Yes, since then the moon has been moving slightly farther from the earth. It's not anything we have to worry about. It will be millions of years before it is noticable to the untrained eye. And many millions more before the moon goes flying off on it's own. ;-)

Answer 2

The orbit of the moon around the Earth actually precesses over 18 years forming a clover leaf motion. So the orbit of the moon relative to the sun is actually an oscillating cycloid. During the year there are about 13 cycloid oscillations of the moon motion around to the Sun.
Any orbital distance and angle of the moon orbit would change but very slow in conjuction to the Earth 's mass increase with time as it receives and absorbs mass from the Sun and other cosmic mass flux from space.
An ice age would occur within a 22 thousand year precession cycle of the Earth poles. At a spin angle such that the earth at certain point receives very little insolation. At that are no biological plant life would propagate.The spin angle of the Earth has little effect on Earth's orbit.
The Earth also has a precession of its orbit due the Earth's mass inrease with time.

Answer 3

Like all Moons, it is slowly moving towards the planet. So it has changed, but it is not due to any thing that is happening on the Earth, just Earths gravity.

Answer 4

The moon has always been slowly moving away.
