As the moon continues to move away, when will it have a more noticeable impact on mankind?

Question

.
It moves a little over 2 inches a year from Earth causing us to teeter more on our axis.

(never use teeter) Got it...

You guys and/or ladies have been very helpful. Thanks.

Answer 1

The moon slowly moving away from earth has two consequences:
1- the level of tides (difference between high tide and low tide) will decrease over time
2- the energy that the moon gains is taken from the rotational spin of the earth, therefore days will get longer as one revolution will take more time

Now, when are we going to notice a difference? If you have an atomic clock, a few years is enough to notice the change. There has been a cumulative adjustment of "leap seconds" to account for that effect on 23 occasions over the last 35 years (see link), for an average variation of 0.65 second change per year over that period, or 6E-10 (0.6 of a billionth part). The rate of change is however supposed to slow down, evidently as the moon moves away, the rate at witch it will slow down earth is bound to reduce as well.
How long before days are noticeably off from the current 24 hours? Million of years. So, not enough to loose any sleep over it just yet.

Answer 2

In my opinion, I've heard that the moon at one time was part of the earth, but was knocked of by a large asteroid. So it used to be very close and cause huge waves ect.. So yes it is moving away and eventually will be drift off into the dark vastness that is space. This will cause the earth to spin off it's rotational path around the sun. Well that's the theory.

Answer 3

When its been out of our lives a few weeks, then we will start to miss it, then eventually realize what a selfish , incensitive, uncaring rude people we are. Being as vain as we are, we will write letters to the moon, begging it to forgive us , yet to no avail, the moon will not return, as we were blind to the cruelty we unintentionally put it through. Either that or the earth will lose its gravitational pull from the moon, the tides will change , seasons will not change, And we will all end up paying for moonie on the streets. Do the words "off your axis" mean anything to you?

Answer 4

You will never notice it because it is happening so slowly. You would have to make a jump in time of a million years to see a noticeable difference from just the moon. It's the other stresses on the Earth's environment that we will see the most change in out life time.

Answer 5

In a few billion years, because of lack of the pull of the moon the earth will pretty much have an axis that will wobble badly. We will lose a constant temperate climate.

Answer 6

It will take more than 15 million years for the moon to move one tenth of one percent further away from earth than it is now. At that rate, it would take about a billion years for it to have a noticeable effect on anything.

Answer 7

The Earth has a wobble that takes 22,000 years to wobble once. It has always done this and it always will. Don't worry about it and don't use the word teeter ever again.

Answer 8

the Earth's rotation is gradually slowing, and the Earth's day thus lengthens by about 15 microseconds every year.

at this rate it will take several million years to have a noticable impact

Answer 9

Uhmmmmmmmm.....No. It always moves back. It's the erratic eccentric orbit that changes. Apogee and perigee, farness and nearness. It gets farthest away then returns to nearest. Always.

Answer 10

Some day we won't be able to enjoy total eclipses of the sun.
