Why You’ve Never Seen the Back Side of the Moon

Through this orrery demonstration, you will see that the Moon isn't just sitting still up there - it's actually spinning on its own axis while also orbiting around the Earth. It takes the same amount of time for the Moon to complete one full rotation as it does to complete one full orbit around the Earth. So, as it spins, we're always seeing the same side facing us! It's like the Moon has a favorite face, and it wants to show it off to us all the time! Pretty cool, huh?

I understand the concept, but i didnt get any understanding from the demonstration. I was expecting the earth to rotate and the moon on its base to also be moving.

[ronkvogel]

Why is Moons own rotation exactly so that it keeps facing the Earth?

[sasmalprasanjit]

Just 1 sentence will be enough to explain and that is " MOON is Tidally locked with Earth gravity "

[shambalaspaceoflove]

If Earth and Moon were spinning....why do we see the same moon face in the sky constantly during hours and hours (whole day) footage?

[anwaralobaidy]

The question is not why we facing the same face... The question why all around the earth see the same face

[dragonboi]

What's the difference between this and tidal locking

[eduardohollauer]

In this instrument the periodicidade related to the moon own rotation must bê regulated by the ratio between the two circles in the orerry (the Blue and Black circles). You should regulamento both radius to provide the correct periodicity !

Well duh, you only hear Dark Side of The Moon, you don’t see it

[Aurochhunter]

Yep, I’ve encountered someone who didn’t think the moon rotated.

[bogdanditu]

But Earth is also spinning on its axis

[chemistcollins]

The Moon is modest so it Never shows its "behind"..😅

[seafoodpizza]

Wow I didn't know that. And I'm old 😅

Interesting fact cars work with water no need for petrol. It's all about making money. The sun the moon are the same size both are smaller than the earth in fact very tiny compared to the Earth like a penny compared to trampoline.

[brendalimitone]

Propaganda. It's not a ball, it's a light, plasma, in the firmament.

[denisebranquinho]

But you forget that the earth is spinning as well...

[vcythandle]

poor explanation.. i don’t think you understand yourself

[AiMachine]

Interesting fact so call Down Under Australia can see the moon at the same time as United States and United Kingdom because it's flat Earth

This is great, BUT you speak much too quickly. Please practice speaking slower, you will be better understood especially by kids ! Thanks !
