Default The moon?

Ok something that I've been pondering for some time.

I'm sure you have all seen that at midday sometimes you can see the moon... Does that meen that the people on the other side of the planet have no moon at night?

I ask this because I have never seen a night with no moon

It's probs a stupid question with a easy answer but... Thought I'd ask anyway

Hey hey,

Interesting :=] I'm hopeless at visualising things and rotating objects mentally, but I had a look on google.

Apparently, the moon is always in the sky at some point at night, where ever you are. Sometimes, though, it's not visible because the position of the sun is exactly wrong i.e. a new moon.

But but but :=] I was just thinking if the moon's visible for you at mid-day in London then for me in NZ (which is pretty much the exact opposite side of the planet) it can't possibly be visible too at the same time (midnight here, ignoring daylght savings lol.) The earth rotates on its axis once every 24 hours and the moon goes around the earth once every 29 or so days. I can't see how there's enough time for either the earth's rotation or the moon's orbit to make it so the moon appeared in my sky at any point that night.

Fuck, my brain hurts now :=] It's really confusing. One website I checked told me that this diagram should make it relatively clear. As clear as mud :=]

yeah it buggered my mind too..... even when its a new moon, we can still see it just, because the earth now gives of a small amount of light.
Idk, maybe next time i see the moon midday, i will PM you to see weather its in your sky lol

I love love it too LC

lol- do that :=] Although, I might lie, I'm a bit contrary like that. Although, we could all be getting it very wrong and this could be Arrakis not Earth, so maybe there's two moons :=]

Actually, I had a bit more a thunk. What I reckon is that the moon will always be in the sky for some hours over a 24 hour period rather than specifically at night. That kinda makes sense. Could be during the day or the night and I suppose whether or not the moon's visible during the day depends on how much sunlight it's reflecting?

To be honest, there just has to be nights when the moon's not visible. It's either a new moon or it's in the sky during the day not at night. I wonder if it's one of those things when you're far more likely to notice and remember the presence of the moon rather than lack of it?

Did you know that the moon rotates at exactly the same speed that it orbits the earth... So we only ever see one side of it.

A general assumption is that the moon used to rotate much faster, and over millions of years it has slowed to its equilibrium orbit, where one lunar day = one lunar year, as mmch85 describes. Maybe it was in a higher orbit around Earth too.

I think the answer to your question about where the moon is, is to say that it rises and sets over your horizon like the sun does, making an arc in the sky that changes position daily. Depending on where you are and the calendar date, it might rise at, say, 2 am and set the next afternoon.

People elsewhere would experience different moonrise and moonset times. I found this: Sun or Moon Rise/Set Table for One Year
