Why Aren't There Eclipses Every Month?

- The moon orbits the earth once per month, which means the moon is on the sun side of the earth every month. So... "why aren't there eclipses every month?" is a question we will answer in this video!

Very kind of him to account for any moon dwellers in this explanation. Forward thinking.
I'll thoroughly enjoy this video even in 2084
Yeah
around that time period it was thought that all planets/celestial bodies were inhabited by life, until we eventually realized that that was silly.
@@thezipcreatorI didn't even think of that, I thought it was just a joke from minutephysics but yeah no, it's true.
It would be nice to get a perspective of an eclipse from the vantage point of the moon.... We likely will in the near future.
It's worth mentioning that the nodes of the Moon's orbit shifts every year thus making the time of eclipse seasons shift accordingly.
Ah right, i did a double take on that one. Would be cool to have an 'eclipse season', though.
This is a really important point!
What causes the nodes to shift? Is it just a chaotic 3-body system? Or is there some simpler physics involved?
Just here for the answer ❤
I would be curious too. Is a a constant shift, so many degrees per year? If not, then what causes variation in it?
1:18 I like the touch of red hue of Earth's shadow accounting for its atmospheric diffraction
And subtly explaining Lunar eclipses without it being the main point of the video
My guy didn’t want to look stupid in case there ended up being “moon dwellers”. Love it.
I had a question as kid that why wont’t planets cast shadows on other planets
@@captainjackson18 They do, and they're called transits.
They can, if they are close enough. In practice, almost none are close enough
@@captainjackson18 That's actually how people detect planets in other solar systems! The method is Transit Spectroscopy. They measure the intensity of the light of a star and look for any dips in light intensity caused by planets passing in front of it (relative to us). The planets are casting their shadows on us from across space!
Futureproofing.
Personally, as a moon dweller, I am glad he remembered us in his explanation. I do love seeing our shadow on the earth.
Stop hoarding all that moon cheese or we'll stop sending you robots to eat!
The moon is not a planet! ruclips.net/video/13R-zKGrXvg/видео.html
So why don't you send us pictures of it? The videos I have seen from low Earth orbit of the moon's shadow on the Earth are amazing!
Seriously, were any of the (before my time) 1960's trips to the moon timed to coincide with eclipses? It would be cool to see from the moon as the moon's shadow crosses the Earth. I also suspect that a lunar eclipse would appear far more spectacular when viewed from the moon that when viewed from Earth.
As a moon dweller, how well did Lucien Rudaux do with his painting of what a lunar eclipse would look like, when viewed from the moon?
One of the very first question came to mind when i first learned about Solar System as a kid……….Finally got the answer after 19 years😅😅
Yeah all of the models and diagrams make them look like they are in the same plane generally
Same and I always thought the reason would be similar to what explained in the video. I never checked it though
Funnily 19 years is a pretty important length of time in eclipses as it's the length of a Soros cycle iirc
You never bothered to look it up?
Same for me, but i came up with the answer myself 5 minutes after at 8-10 year old
I love it when the "it is no wonder" section actually is "no wonder". Looking at you math books and their "left as an exercise for the reader" bits
The times it was "left as an exercise for the reader" and instead I just didn't get it.
We do live in a 3d world guys
Maybe
says the person in my 2d computer screen
Solar system is pretty flat though
truly a multidimensional experience being provided here
Let’s see: Mercury…Venus…Earth! I guess you’re right. 😃
this video felt very nostalgic with the double bass and the talking pace, just like 10 years ago videos. i like it this way ❤️
I love how the childish depictions are so seamlessly and professionally animated, so much so that you don't even notice the transition. Very clever on the part of the animators.
That was amazingly clear
Yeah
Simple, clear, effective, I love it!
Jason Gibson did a video covering this a few days ago too. Since I was 6 years old I felt I was pretty astute with astronomy but both of you blew my mind this week.
I've missed short and sweet Minute Physics videos like this!
The moons orbit got a wonk and only 2 nodes, nodes and wonk need to align for an eclipse
#RespectTheWonk
#wonk4life
It's not often minutephysics has to result to using 3D animations. So cool to see!
Resort*
In short, space isn't a flat plane. Therefore, eclipses can only happen when the moon lines up with the sun and the earth such to create a straight line.
This is beautiful work. Well done.
The dialog, the double bass, the deliberately cartoonish sketches, the animation. Nice video.
Or in modern day vernacular: this be low key da best no cap.
I did pose myself this very question following the recent eclipse, and had my reasoning confirmed by this, and fergusons explanations.
Both Veritasium and Minute Physics uploaded yipeee!
Thank you. My 9 year old asked this question a few weeks ago. I'm going to show him this video. So clearly and simply explained.
I need like an entire documentary just filled with diagrams of the earth, sun, and moon to fully wrap my brain around the way they all move around. 😵💫
My man Ferguson knew that we'd land on the moon someday and decided to account for it in his explanation. Smart man, he was.
Could you make a video explaining the Saros cycles too? They are related to the eclipses as well.
Short answer: because we live in a 3D world, not a 2D one.
You see, THIS is what the internet is supposed to look like. Educational, informative and engaging. Not bikini teens doing a samba. Great work!
It's both.
Best eclipse explanation EVER
I love minute physics. Thank you for the content.
Same
I still find it weird when people say her instead of it for inanimate objects.
English used to have gendered words just like French, German, etc does today. RobWords did a great video on it (Why doesn't English have genders? Well... it did!). There are still some holdovers, such as ships and (in this case) celestial bodies.
In ye olden days by default any inanimate object is a woman while any animate object is a man.
Ah, I dunno I just use it for celestial bodies and ships. I didn’t know that English used to do that way in the past. That’s interesting.
Come on, it´s the Moon! Show some respect! hehe.
@@theonlylolkingBut the moon moves across the sky and around the Earth. By this standard, wouldn't it be masculine?
Oh ! So that's why ! Thank you for the explanation.
A 200-year-old perfect explanation, with all the math to prove it. I'm so ashamed of how we live in the age of information and yet so many believe in the lies of the flat earth, of geocentrism, or hologram moon, etc
There's a similar old "for dummies" book that holds up well on calculus (not nearly as old, it's only from 1910). Its name is Calculus Made Easy and its motto, referencing how many calculus-knowers are fools, is "what one fool can do, another can."
You forgot to mention the moon's orbit is also elliptical, so even eclipses aren't truly full if the moon is at it's apogee in orbit when one occurs.
That's how we get _annular_ eclipses!
@@fromnorway643 I know, that's why I mentioned it, because some people watching this might think the moon's orbit is circular.
@@fromnorway643 I'd like to see what an annular lunar eclipse would look like. The moon would have to be 4 times as far away as it currently is, for that to happen, and it also wouldn't be in a stable orbit since that's beyond the L2 point of the Earth and Sun, but I'd be curious to see what an antumbra would look like if it were influenced by an atmosphere.
@@carultch
Sorry, but that's incorrect!
The Moon's core shadow or umbra is on average slightly too short to reach the Earth, but it can do so when the Moon in its elliptical orbit is closer to the Earth than average, meaning that annular eclipses are slightly _more common_ than total ones. Here's an example seen from China in 2010:

And here's one seen from Colombia in October last year:

@@fromnorway643 I don't think he was referring to annular SOLAR eclipses, I'm pretty sure he was referring to annular LUNAR eclipses (hypothetical).
I asked myself this EXACT same question after April 8th's eclipse. THANK YOU FOR SUCH A GREAT EXPLANATION DUDE!
That is so elegantly described. I love it. It borders on art.
I love the way you explain things. I could also listen to you narrate all day.
Thank goodness for the Playback Speed feature on YT. My kids loved the video at 0.75x.
Interesting topic, short, to the point, cool drawings, and simple but clear explanation. This is minutephysics at its best
Great video!! Makes me feel incredibly respectful and humble to know that someone 250 years ago can write such a accurate and detailed explanation for this. The that that human is able to propagate knowledge to the future generations truly sets us apart from other species on the planet doesn’t it? Amazing!
A warning stating one should not view a solar eclipse with the naked eye should have been included in the video.
That's right! That's why seeing an eclipse is rare! 👍😀
Nice to hear from you after a while! Keep going bro 🤝🏻
Those 1757 illustrations are awesome.
The animation in this video was top notch! Great work!
I drove to the dead center of the Great American Solar Eclipse in Sylva, NC in 2017. One of the most amazing things I've ever seen. I highly recommend everyone go see one who has a chance to.
Amazing and intuitive animation at the end. Great work!
Brilliant, I have wondered about this and never considered the angle of the moon's path relative to the earth. It's so obvious!
However, does this mean that if the moon's orbit were aligned with the orbit of the earth around the sun properly, we *could* have an eclipse every month? And if so, this almost certainly happens somewhere in the universe, right? A neat idea to think about for an SF story set on another world!
In our own solar system, many moons _do_ orbit over their parent planet's equator, or close to it. Pretty much all the large moons do (aside from our own). However, none have that right combination of size and distance to appear so nearly the same size as the sun from their planet.
An interesting question which I never considered. My first thought was that it simply didn't happen over land, but I see now that my hypothesis was wrong.
Great explanation! Short and memorable, thanks to the simple and clear animation.
I figured that was the answer but this is a great animation!
So, if I understand the relevant math correctly in most years there is at least one solar eclipse, sometimes two, sometimes none. But since they are only visible from a small portion of the Earth at a time you should only expect one to be visible in your neighborhood once every few decades.
I have wondered about this since I was a kid. Thanks for clarifying!
It would be much cooler if we did get eclipses every month.
In Kerbal the orbit of Mun is exactly in the plane of the Kerbin's orbit, and thus gives frequent eclipses. This confused me the first time my spacecraft was caught in the shadow of Mun and all my solar panels stopped working.
Thanks so much for uploading this really clear explanation
James Ferguson? Amazing. Great sense of humor and understanding of his limited understanding too.
Excellent explanation and illustration
That was…incredibly helpful. Thank you!
This also explain how full moons are full. Its full when she is behind earth, so how come earths shadow hide her?
I always wondered this and thanks to you now I know
How he teaches a such topic in 2 mins , I will like i crash courses . Really loved the video .
Very interesting curiosity I never searched for before. Thank you.
Your way of explanation is outstanding 😊😊
This 'nodes' are called 'rahu' and 'ketu' in indian astrology
Amazing, short and damn informative. You got a sub
I truly wonder how many people (despite being taught differently) think the Earth casts a shadow on the Moon and it’s the Earth that causes the Moon phases. And then they’re super confused when there’s an actual lunar eclipse.
That's a good explanation. I never thought about it, but now I don't even have to think about it. It makes sense. Thank you! I'll never use this in my daily life, but it's fascinating.
There are practical applications of this knowledge. To send any interplanetary spacecraft, you have to account for orbital inclinations. It may seem insignificant when most orbital inclinations of planets are single digit degree values, and the solar system would seem to be basically flat, you'd miss by thousands of miles if you didn't account for orbital inclinations.
A perfect explanation, thank you!
Very Good. You should do a commercial series for Junior High School and High School science.
Sheet my head hurts even more after this
Did the olde-style speak in this give anyone else CGPGrey vibes?
always nice when your intuitions prove correct
It is something to remember that most of the knowledge we have was accumulated centuries ago (such as how eclipses work). Eliminate books and any technology retaining that knowledge (such as with a modern day Carrington Event) and most of technologically dependent people on the Earth will likely be thrown into utter chaos. Most don't know how to survive without a grocery store or a refrigerator. I'd think within a year or two, the human population in non-agrarian parts of the world would die off, either by starvation, disease or by pure savagery due to the latter.
I was literally pondering about this the other day and then minutephysics dropped a video for the same, I'm concerned.
As a moon dweller I am glad for some representation
Man... If only the tilt of the Moon's orbital plane was just slightly lesser.
maybe its a good thing it isn't. otherwise we wouldn't cherish these rare events as much if they happened everymonth, just like most of us dont find the new moon to be a big deal.
@@hamzahkhan8952 They wouldn't happen every month everywhere on Earth though, in any particular place they'd still be rare
@@galoomba5559oh yeah true. i forgot about the earth's axial tilt
I'm a math and science educator. Nicely done! Thanks. :)
„her shadow“?
It is tradition to call big ships with the feminine pronoun. I guess earth and moon are just really big ships.
Yes, the moon, i.e. "Luna", used to be a "she" in English, for poetic reasons. See also Act II Scene II in Romeo and Juliet.
thank you so much
TL;DW there isn't a solar eclipse each month because the Moon's orbit around the Earth is tilted relative to the Earth's orbit around the Sun, so the Moon usually passes above or below the Sun from our perspective.
Illustrated by me - love that!
Such a simple question. Such a beautiful answer.
Could you make an explanation about how the new lunar month starts at different areas of the world?
Thanks for this clear explanation. I'mm pleased to learn that the inclination of the plane of the moon's orbit around the earth is 5 degrees from the plane of the earth's orbit around the sun. Now, do you know the inclination of the plane of the earth's orbit around the sun to the plane of the Milky Way? (I know, it's not exactly a plane, but it's approximately planar.)
About 60°
Out of curiosity - does that degree of rotation mismatch apply elsewhere notably in the solar system? Respective to the Earth, ideally, as I am kind of presuming this already happens with, say, Jupiter and its moons.
Yes, it does. Jupiter's moons also have those, but really they happen almost every time the moon passes in front of the planet due to the massive size of Jupiter.
A, geocentric astronomy at the end is chief kiss.
Great explanation! Thanks
I could have used this video a few times in my life hehe
Thank you for this nice video
that makes sense.
also, this is the fastest i have ever reached a minute physics video (12th comment)
Same
short explanation: the moons axis is tilted. boom shakalaka.
I didn't know the real explanation but I assumed this was the case when I saw the title of the video. Glad it's a simple explanation since it means I was correct :P
stop at 00:15 and look at those
Can you go over that again in 21st century English??
The moonchad yeets its rizz over the drip line so it hits different. Otherwise it would be super mid. So when it doesn't get shaded the sun skeets onto the earth. No cap.
@@narfwhals7843 I did not understand this. Get off my lawn.
@@narfwhals7843 You left out three unnecessary "literally"s and 17 "like"s
Same can apply in inverse for the lunar eclipse, however it is far easier to witness
We should adjust the moon's orbit to make it happen every month
I kept wondering that but I couldnt find how
Great video. Good for world building.
Watch this one at 0.75 speed. Guys, it's way too fast.
Ed. It is a cool one, though.
If a eclipse was seen every month then that would be BORING!!! 😂
Would love to see schedule of total eclipse by city over last and next millennium.
I got to see the 2017 total eclipse when I live in Tennessee. It was awesome. I live in Minnesota now, so I won’t be in the path of totality like I was seven years ago, but that’s ok. I have the pictures.
