Working Model - Sun, Earth and Moon

Explore key events like phases of moon, Eclipse, zodiac transition with the help of this mechanical model.
Let us understand various events associated with Sun, Earth and moon with the help of a model.
Model is built with small balls, beads and lots of gears. Let us assume that we are way up in the sky and observing these objects from a pole star. Earth revolves around the Sun, not in clockwise direction but in anti clockwise direction.
During this journey around the Sun, it also rotates around its own axis. This axis is not straight but slightly tilted at an angle of 23.5 degrees like this. This tilt is the reason we have seasons on Earth.
Just like it's revolutions around the Sun, Earth also rotates in anti-clockwise direction around it-self. One complete rotation around itself takes 24 hours while one complete revolution around Sun is finished in 365 days or 1 year. Let's take help of this dial so that position of Earth can be referenced as it revolves.
There are numerous stars around our solar system. These were grouped by our ancestors for easier identification. Also know as constellations. There are many but 12 are most important. These constellations mark out the path that Sun appears to take throughout the year.
Mostly known to us as Zodiac signs. Circle is divided into 12 equal parts. One part per zodiac sign.
This outer ring has months marked on it as per Gregorian calendar. Useful while discussing Seasons.
Zodiac signs are arranged like this… Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces.
And months as January, February, March, April, May….
Let's move Earth by hand in steps and study orientation of axis as it revolves around the Sun. Front view is better for this instead of top view
This imaginary line represents Equator. It divides Earth in two equal parts. Northern hemisphere and Southern hemisphere.
Let us start with 21st June.
21st June is the longest day in Northern hemisphere. North pole is at its nearest point towards Sun on this day. Hence this part gets more sunlight. Longest day and shortest night.
Exactly opposite situation is there in the southern hemisphere. Longest night and shortest day .
It's also known as summer solstice.

This is the best, what I have ever seen about the Sun - Earth - Moon relationship!! Congratulation and thank you very much!!!!🥰

[@TheWeightOutdoors]

As someone who relies heavily on visual depictions in order to understand & learn, I found this video to be remarkable. Thank you, so much.

[@RavindraGodbole]

Welcome

[@kishorambi2614]

I want to make this project in can you help mi for this

[@beeankha]

Amazing model!!! Only critique is that it doesn't show the elliptical shape of the earth's orbit around the sun, but otherwise fantastic job and great explanation - I really like how you added parts as you went along, which makes it easier to digest the concepts. Will be using your video in future teaching :)

[@RavindraGodbole]

Ok, thanks

[@amudhadhanabalan404]

Very beautiful explanation sir. The effort you have taken for a visual view is remarkable

[@MelissaAvery-h4b]

This is great. This really helps visualise the relative positioning of the Sun, moon and earth. Adding images of the stars would add an extra level of detail

[@RavindraGodbole]

Thanks for the suggestion. I will explore how images of stars can be added.

[@MrTomEdo]

The step by step explanations work extremely well here. Even someone with almost no knowledge in astronomy should be able to grasp this model and understand why certain phenomena happens. I feel like it would be great for schools to create such models to explain basics of the earth orbit to children.

[@RavindraGodbole]

Thanks

[@theplacebeyondthelies2429]

but it's false, it doesn't work, don't be fooled by models, observe reality as it is and you will learn the actual truth.

[@aa16121978]

Excellent model sir, it's beauty lies in the simplicity of explanation.

[@sasi0263]

simple & crisp info. thanks

[@krithikagokulnath4160]

Sir, Please make this available like a model project as a DIY kit.. amazing 🙏🏼

[@RavindraGodbole]

Thanks. I have built another version with Acrylic but its slightly bigger. Will work on the DIY kit in near future. All the details about the model is in the link available in description.

[@tiemposdelruido]

@@RavindraGodbole I'd buy that kit immediately!!!

[@lcguerrerocovo]

@@RavindraGodbole would also buy a kit, this is amazing craftsmanship :)

[@stanzinnorlha-x7n]

Sir ... Very nice explanation. ..

[@sudhirphadke3630]

Very useful information.!!!!!

[@knagrawal]

You have developed a very innovative model, which can be very helpful in learning by school children, the relative movements of Earth and Moon with reference to the Sun. Are such models available in market place?

[@RavindraGodbole]

Let me know if you are interested. I can make one for you. Here is the latest version. kzbin.info/www/bejne/j2TIkqppaLCXppY

[@whynotcreatelove]

Brilliant! Thank You

[@muraliganesan3605]

What is that material u used. Is that cardboard

[@kneedragnr1]

Oh, but you forgot about the supposed aphelion and perihelion. How does the supposed "23.4° constant axial tilt" account for the seasonal changes, which would merely be a few thousand miles, at best and the supposed 3.1 million miles difference between aphelion and perihelion not make any difference?

[@RavindraGodbole]

Thanks for the note. I wanted to cover it as a separate topic. Here is the video and model for the same. kzbin.info/www/bejne/aIe5n4B3aNJnZtEsi=_vSNIUitRHenm3DE Right now it is not in English but you will get the idea.

[@dipan246]

Thanks it was very interesting, I understand somethings 🎉🎉🎉

[@mine4548]

Awesome clip!

[@SamirGholap-b3u]

Please make video on काळसर्प दोष

[@sciglassblower]

The Earth rotates counterclockwise around the Sun? What if you are looking from the other direction, south instead of north? Like many things, it depends on your perspective.

[@RavindraGodbole]

You are right. It depends from where you are viewing. I have mentioned that if we look all the way from above the north pole towards this sun, earth, moon system then its rotation is anti-clockwise. it will change if we look from down under !. Rotation of speed around earth is not to the scale. It is the number of revolution which is discussed and not the speed. There are many things which have to be assumed/simplified in order to explain a particular concept. Hope that helps.

[@shareesecastillo8725]

Can you help explain how tides are affected by the moon if moon phases are simply portions of light reflected from the sun?

[@beeankha]

this has a little animation that explains it: oceanservice.noaa.gov/education/tutorial_tides/tides05_lunarday.html

[@the4playz828]

Can you also add the moon's apsidal precession, please? With more accurately, Love your project, I'm also going to do it❤

[@RavindraGodbole]

Thanks for the inputs. That will need another model though. It is also in my TODO list. Eager to know what you come up with.

[@gowthamreddy824]

Excellent video

[@RavindraGodbole]

Glad you liked it

[@sophlefnort]

At 10:30 why does the shadow of the solar esclipse (the moon shadow) move from west to east? Its path of totality moves from west to east. The moon moves slower than the earths orbit and that's why it appears to rise from the East. But for some reason during the eclipse it was coming from the wrong direction.

[@RavindraGodbole]

Need to investigate further. Another model on the shadow movements during eclipse can help.

[@sophlefnort]

@@RavindraGodbole This is definitely showing movement from west to east. kzbin.info/www/bejne/qJvdZIGgbrF4hKM Starting in Oregon and going through South Carolina. Thanks! Really great model you did though!

[@JayanP-o6c]

is this model available to buy

[@RavindraGodbole]

Yes. Please connect on whatsapp [phone] Here is the updated version : kzbin.info/www/bejne/j2TIkqppaLCXppY

[@sophlefnort]

During a lunar eclipse, does the earth move infront of the moon over the 2 hour period or does the moon move into the earth's shadow over a 2 hr period?

[@RavindraGodbole]

Both are moving. Moon covers more distance in the same period

[@sophlefnort]

@@RavindraGodbole In your model where would the moon be for the lunar eclipse to happen and why doesn't it happen every fullmoon?

[@RavindraGodbole]

@@sophlefnort moon orbits at an angle of 5 degrees. Hence it does not happen every full moon

[@bonggojbihonggo991]

👌👌 🇧🇩

[@krishnendusengupta7068]

Good attempt. But our earth revolves around the sun in an elliptical path, not a circular one.

[@RavindraGodbole]

Thanks. It's challenging to build an elliptical path. Still thinking 🤔.

[@kitcanyon658]

At the scale built you wouldn’t be able to see the amount of non-circularity.
