How long till the Earth becomes tidally locked to the Moon?

Question

The moon is currently tidally locked to the Earth right? So how long till the Earth becomes tidally Locked to the Moon?

Answer 1

The time earth takes to spin once around the axis will be the same time it takes for the moon to revolve once around the earth.)

The effect on the Moon is static because the Moon no longer rotates in relation to the Earth. All these exerted forces are costs in energy. They have to come from somewhere. The Moon did have a much higher rotation rate long before anyone was living on the Earth to observe it, but the tidal forces slowed it down until it reached an equilibrium point, i.e., where keeping the same face toward the Earth was the point of least expended energy. Both will still rotate, both keeping the same face toward the opposite body.

Moon is going further from it's orbit so there will be less effect of the pull of the moon and visa-versa over millions of years.

There is a formala at

I think you should say with earth becomes tidally locked to the sun.
Screw it, I don't know what I'm talking about.

Answer 2

Not for a long time. The slowing effect of Earth's rotation caused by the Moon, is a long process involving tidal coupling and gravitational locking. The current estimate is another 4 billion years until Earth shows one side to the Moon as the Moon currently shows towards Earth. By then, the Sun will be at the later stage of it's life and will be preparing to enter it's Red Giant stage.

Answer 3

The average distance from the earth to the moon is about 240,000 miles. The earth and moon are already tidally locked, meaning they both orbit a common center of gravity. Because the earth is much more massive than the moon, that center of gravity is within the earth.

Answer 4

The Moon's origin as a disk of material which coalesced in orbit with no original concentric spin explains the rotation matching the revolution of the Moon.

I haven't a clue, and don't know that the answer is available, but I can say with certainty, it's not anytime soon, Perhaps not even in the lifetime of our sun.

Answer 5

This is from memory, but as the moon slowly moves away from the Earth, the *rate* at which time is added to our day slows; If I remember correctly, I think the moon's period will be 39 or 40 days, and it'll be around 12 billion years from now.

Answer 6

Just an educated guess here..........but it probably won't because the earth is bigger than the moon.

Answer 7

Never.

Answer 8

mmmmmm gd ?not for a very long time

Answer 9

Never----

Answer 10

This sounds celestially kinky!
