moon

Last night I looked from my window and saw the moon. How long is it before I can see the moon in exactly the same place again!

[Zacs-Master]

Technically as were all flying thru space it will never be in the same place again.

From your window? You can probably see it again through it tonight.

1 lunar month = 29.53059 days, if that is any use.

Since the distance between the earth and the moon is increasing it will never be in the same place again.

The moon was extra high last night. I don't think you'll see it that far above the horison from your window again until 2020.

It will take at least 18.6 years for inclination in the Earth's axis and the inclined orbital plane of the moon to coincide to put the moon in the same apparent position that you saw it in last night. As to whether this will happen at the exact same time of night would depend on a more precise figure for the the 18.6 years being divisible by 24 (hours) to result in a whole number. If it isn't a whole number, you'd see the moon in the same position, but somewhat earlier or later in the evening. To obtain the same time as last night, you'd have to to keep multiplying the 18.6 years to obtain a figure that would result in a whole figure when divided by 24.

Thank you for your answers, I think I know what you mean, so if it is 18+ years, I may not be around to see it, by then I'll be well into my 90s. I'll probably have been carted off to an old peoples home by then. You never know though!

If you go to an old peoples home nearer the equator it will appear higher.
