(First, since this is a common problem which many people notice in people's writing and is not a typo but a misunderstanding of our grammar: "its" is possessive and "it is" is contracted to "it's", though other possessives have an apostrophe, because they used to have an "e" in them which is now dropped.)
I cyber corrected.
Second, the Earth will still rotate around its axis if its forward momentum is stopped somehow. That is the answer.
I was specifically talking about the Earth eventually doing
with the Sun what the Moon does with the Earth now. It will
slow down to match and become tidally locked in the future. I
wrote nothing about stopping it's movement, only the slowing
of rotation which is inevitable. You didn't actually answer
my question unless you can somehow explain how the Earth's
behavior with the Sun is different from the Moon's behavior
with the Earth.
Quoting: DrPostmanThe latter IS different, because the Earth actually spins on its way forward, as well as rotates around the Sun. It also has a movement of rotation with the Moon forward with the Sun. Yes? Now, if the Earth's spin is only due to its relationship with the Moon, and not true spin either -- something I am not sure of because of the barycentre dual system -- then yes, if the Moon were not there the Earth would not rotate, only move forward (as the Moon does). I suspect, however, that since it is its spin which determines the Moon's direction, the Earth would still spin if forward momentum alone stopped. In other words, that the Moon pulls it a bit off its direct spin, into a dual rotation instead of direct true spin. Clare
