Moon Phases animation

View of the Moon's orbit from both overhead and tracking views. Notice how, from above, half of the Moon's surface is always lit by the Sun. The phase we see is just determined by how much of that lit half we can see from our viewing angle.

Don’t forget- the moon isn’t in an equatorial orbit. It’s roughly 10° “above” the equator on one side and 10° “lower” on the other.

Thank you so much i just couldn't imagine how it "change phases"... And i needed something just like this! Thank you ❤

SOMETHING IS MISSSING, MAYBE, NEED TO SHOW A THIRD ONE SIMULATION SHOWING ALL MOVEMENTS TOGETHER, 🤔🤔🤔

O movimento da Lua se dá suavemente junto com o movimento da Terra girando sob si mesma. Como não foi mostrada a rotação da Terra vc se atém mais ao movimento da Lua ao redor sofrendo a ação da luz solar. Temos então a sequência Lua nova - quarto crescente - meia Lua - Lua cheia - quarto minguante e assim segue o ciclo.

So whenever there is a new moon there is a solar eclipse??

[@TadThurston]

That's the right idea -- the more precise way to say it is that solar eclipses *can only happen* during a new moon. What's really going on is a bit more complicated. If the Moon's orbit around the Earth was really in the same plane as the Earth's orbit around the Sun (like it's shown in most diagrams) then you'd be totally right. But the Moon's orbit is actually 5 degrees tilted, so most of the time the Moon is a bit above or below the position of the Sun and there's no eclipse. Only when they line up just right would you see it. I'm working on a new little movie that shows that very thing.

What about its punk phase 🤪 you never hear bout that one 🤔

And then you realize that it’s flat after all

[@TadThurston]

Sheesh, I hope not, because then it's 35 years of astrophysics (for me) and 2200 years of science down the drain...

Flat earth makes more sense.

[@TadThurston]

It's odd -- before a few years ago, I was pretty certain that there were no actual flat-earthers except for kids under 5 or internet trolls... but now I think they actually exist!

[@zakwanberlin]

How? The widely agreed upon flat earth model shows the moon and sun as 2D disks that act almost as spotlights, circling over the plane of the Earth. How would something circling above head ever appear to set BELOW the horizon and your head. Another thing is the moon is clearly a 3D object with shadows.

[@TadThurston]

The Moon orbits the Earth counterclockwise as seen from above the N. Pole -- you can verify this yourself next time the Moon is waxing crescent or first quarter by watching it move eastward each night.
