In 2013, motion and orbit of the Moon and the Sun and the Earth (astronomy teaching materials)

This is a video of movement and orbit of the Moon and the Sun and the Earth in 2013.
I mede this as astronomy teaching materials.

In the two videos of the lower stage, orbit and size of the Earth and the Moon and the Sun are deformed. When they are deformed, the shadows goes incorrect. So I set they never cast shadow over each other in the rendering software’s setting.

In the upper side video, orbit and size of the Earth and the Moon and the Sun are real.
The Earth in the left side video is viewed from the Sun. The Moon in the right side video is viewed from the Earth.

Here The Earth and the Moon will cast a shadow over each other. So you can view the eclipses. However, the Earth and the Moon are very small compared to the size of orbit of the Earth, the position of shadow is not accurate by the error of rendering software. Why the Earth and the Moon are jiggling is on the same reason.

1 frame = 1 hour. Because it is 24 frames / sec, 1 second = 1 day. The position of the Earth and Moon in the first and the last frame, and the Position of the Earth of the first day of every month are accurate. In the other frames they are not accurate, because the speed of the Earth and the Moon are assumed as constant. ( In reality, they are not constant because their orbit are oval. )

- A yellow ellipse surrounding the sun is the orbit the Earth.
- A character of γ with a yellow line running through the the Sun is the direction of the vernal equinox.
- A red line towards the earth from the sun is the direction of the perihelion of the Earth.
- A gray ellipse surrounding the Earth is the orbit of the Moon.
- A gray line running through the Earth is the intersection of the orbital plane of the Earth and the orbital plane of the Moon.
- Two lines of light blue is the range of eclipse season.
- A Red line toward the Moon from the Earth is the direction of the perihelion of the Moon
- A red line on the planet is 0 degrees longitude.
- A Short red line running through the Moon or the Earth is the rotation axis of each.

ABOUT ECLIPSE IN 2013
Between noon on January 1, 2013 and noon on January 1, 2014, There are twice solar eclipse and once lunar eclipse and twice penumbral lunar eclipse.
- A partial lunar eclipse on April 26, is reflected before and after the frame of 02:00.
- An Annular solar eclipse on May 10 is reflected before and after the frame of 11:00.
- A penumbral lunar eclipse on May 25 cannot be seen on the Moon, however the Moon passes behind the Earth after the frame of 04:00.
- A penumbral lunar eclipse on Ovtober 19 is reflected after the frame of 01:00. the 19th October. the bottom of the Moon is slightly dark.
- An annular total solar eclipse on November 3 is reflected before and after the frame of 09:00.

If any wrong English, please teach me.

One of the best astro-simulations I have seen! The moon phase simulation is like a cherry on top! :D Thank you Astrosimulator keep up the work!

The moonrise seems to vary along the horizon throughout it's 27 day cycle.. For instance, here in the northern hemisphere in the winter, a new moon will rise south east with the sun while a full moon will rise much farther north in the sky indicating a significant change in orbital inclination throughout it's 27 day trip around the earth. Also, the opposite in the summer as a new moon will rise North of east, and a full moon will rise south of east. How can you explain this variation with the moon having a fixed orbit around the earth?

@ 6:03 Came to this video wondering why the moon changes position from winter to summer opposite the sun's position. Wouldn't the moon appear to be in the Southern horizon during the day? Shouldn't the moon's position stay the same throughout the seasons if the rotation around the earth is fixed??

[Johntheheroman]

Thank you for producing this. It is very informative and is exactly what I was searching for.

[aleksandar]

How do you explain that Moon shadow goes from west to east during a Sun eclipse, when your animation shows different?

[lornaduwn]

If this is accurate, then why does the half moon sometimes look like a bowl in the sky? Throughout this animation the dark/light division remains basically up and down not across.

[donconrad]

Exceptionally well done. Thanks for your great work.

[ForensicCats]

Astro, please allow me to share this on my channel? I will, of course give your channel full credit for this data...

[mahsiseua]

ok i understand how eclipse was formed but from this model, why it looks like eclipse should happen every month?

[Cassie]

so why is the moon lite up when it is on the far side of earth ? Shouldn't the earth be making a shadow on the moon?

[gibbsbg]

So the moon doesn't spin around its own centre? Its one side is locked to the earths centre? is this right?

[Sandra-qtsv]

La Luna no tiene su órbita algo inclinada respecto a la de la Tierra?

[surendrasharma]

Does the moon has a fixed orbit around the earth?The moon appears to rise from a point in the east and travels to west following a typical path, in summer; and this path appears to be the same as traveled by sun in winters. can any one explain or give a reference where I can read the information. Thanks.

[bujorcristian]

The animation even though is nice is incorrect as the Moon never goes "forward" and "backward" related to the Sun, it only goes "forward" related to the Sun while orbiting the Earth.

[beninchicago]

does the moon actually wobble or is this just a mistake in the video

[jrjmc]

Can you show the moons movement across the horizon from day to day ? Moonrise

[renjithpr]

Super, thanks... Now I got some idea about how Sun, Earth, Moon rotations

[Pinkmaster]

This really helped me a lot! Thank you!!!!

[jlin]

Could someone tell me why the axis of the earth on the upper left corner is changing?

[Guinea]

given this model and the idea that the moon rises in the east and sets in the west because of the speed of the earths rotation in relation to the speed at which the moon travels across the vast distances of the horizon.. how does the shadow during the solar eclipse cast from west to east? can anyone explain this.. cause anytime i picture the moon casting a shadow it seems like we should experience it on earth from east to west just as we experience the moon itself.. what makes the shadow of the moon travel faster than our rotation? is it the shape of the orbit? like if we connected a laser beam from earth to the moon... i don't think the laser beam is going to travel faster than our rotation because then how would the moon rise in the east?
