Really fascinating. So many things I am hearing for the first time. Very interesting how 12/25 is one of the four days when the sun time and clock time match.
HI, It's a little more complicated than indicated. The tilt alone creates a figure 8. The eccentricity moves the 'crossing point' away from the center. And the offset of the perihelion from the solstice rotates the u about the y-axis, making is asymmetrical in the left-right dimension.
If you own a globe, try this neat experiment. Place the globe a few feet from your fireplace. If you've got the northern hemisphere tilted away from the fire, the after a few minutes the top half of the globe will be cooler to the touch than the southern hemisphere. Repeat for different "seasons" on your globe's hemisphere.
+Technoguy3 In the Northern Hemisphere it is winter now because that end is tilted away from the sun. But because the Earth is at perihelion (closest part of orbit to the sun) the winter is slightly warm. In July, the Northern Hemisphere has summer, but it's at aphelion which has the effect of making the summer slightly cool. So in the Northern Hemisphere, summer and winter temperatures are mild because the tilt and distance partially cancel each other out. In the Southern Hemisphere, they add together which makes summer and winter temperatures more extreme.
It looks like the Earth goes through many kilometers of distance changes in its elliptical orbit but the tilt does not account for that big of a distance. So why does the tilt cause greater temperature fluctuations than the Earth being further away from the Sun?
Technoguy3 That's a good question, given that the difference in distance from the Sun between perihelion and aphelion is about 5 million kilometres, compared to the Earth's diameter which is only about 12,800 kilometres. In going from perihelion to aphelion, the total energy we receive from the Sun decreases only by about 6.3%. This is because the difference in distances is still small compared to the average distance from the Sun (150 million kilometres). So his change doesn't have a big impact. The side of the Earth that points towards the Sun is the side that receives more _direct_ energy from the Sun - about 62.5% of the total. While the side that points away is left with 37.5% of the total. So in going from winter to summer, the increase in direct sunlight is 67% [(62.5-37.5)/37.5]. So when the *Northern Hemisphere* goes from mid winter to mid summer, the change in the Earth's distance from the Sun causes the Earth's total energy received to be reduced by only 6.3%. But the axial tilt means that the fraction of that total energy that falls on the *Northern Hemisphere* increases by 67% - this is more significant and that's why it's the tilt that causes greater temperature fluctuations.
I was just wondering if we could record the sun's position everyday on the same time every single day. Never knew it would be something named *Analemma* , Great info 👍
I have been expecting video's about earth orbital rotation. Thanks a lot for excellent explanation and fascinating animation. Background music is cool...

Watching these kinds of TED-ed videos is like making new connections between neurons in your brain coz you always learn atleast 1 new fact after each videos 🤭
+Fran Selles are you from Australia as well? I am from the UK and December is in the winter for us and I was so used to that fact that I was surprised about the initial comment.
When I was a child, I saw the sun moving in a double figure eight pattern in the sky as I was walking along side some railroad tracks. Later before my father died, he told me that he gave me some kind of LSD which would explain this experience I had
And for the record I say all rotation is being produced by the ocean's rotation only and simply by reflection from below to above, like a record player playing none stop while the ocean levels decrease and increase creating winter spring summer and fall with a rotation affect and the sun light comes from volcano Ambrym in front of Australia.
So during summer in the southern hemisphere, the closer distance to the sun in January equates to hotter temperatures in Australia compared to Canada in July?
I totally understand why it would be on different heights, but the elliptical movement of the earth relative to the sun technically doesn't explain why it goes in eights. Maybe it is because I understood the ellipse as if it is "flat" towards the sun? Or is the ellipse itself tilted as well?
You wouldn't even need to leave the solar system to find a different shape analemma - we could just trace the pattern observing on any rocky body in the solar system, provided we stay all or almost all of its year and do observations at its noon.
The last bit confused me - as in, I couldn't picture why the elliptical orbit would result in a figure of 8. I know it's not that complicated, but unless I have a picture in my head - I don't have the 'ah-ha' - because I only think in pictures. Early christmas drinks may not be helping.
How is earth's axial tilt independent from the sun? Why is the earth "bound" to the sun due to gravity, but the direction of the tilt of it's axis is not? In other words: How does the north pole point to polaris at all times? How does the axis "know" where to tilt/where to point to?
I dont quite understand, the tilt of the earth makes seasons because the northern hemisphere is closer/further from the sun, but the orbit of the ellipse (a difference of 5 million km) doesnt make seasons?
+PapaKay The tilt doesn't create the seasons because of the distance change, but because of energy loss. When it's summer in the northern hemisphere, that hemisphere is "looking" directly into the sun and absorbs more energy (longer days, sun higher in the sky). When it's winter, it faces "up" towards the empty space and doesn't absorb that much energy from the sun.
+PapaKay Yep, time exposed plays a big role. But it also has to do with the intensity of the solar radiation that the hemisphere is exposed to. You see; "The maximum possible intensity of radiation that may be received at a particular location is determined by the latitude. Those rays of the sun are received vertical to the surface of the earth pass through the minimum amount of the atmosphere. [...]. Oblique and tangent rays have to pass through a considerable amount of atmosphere before reaching the surface of the earth." [Oakeley, 1961, p27] So, when it's winter, the northern hemisphere is tilted, so it receives tangent rays from the sun, which have to penetrate a bigger amount of atmosphere before they reach the ground. And when they eventually reach it, they are really weak. The opposite happens in summer.Hope that helps ;)
@@itskelvinn Not only time exposed, but the tilt also causes the light to travel through more air particles before reaching the ground. Essentially losing most of its energy and giving more time for the atmosphere to reflect more of the light too. When we’re facing the sun, it basically comes down in a straight path so less time being reflected and losing energy.
@@ofigetdaitedve Only two seasons in the top end, wet and dry. Average daytime high Darwin, middle of 'winter' 31°C. Overnight average low 19°C. No place for snowflakes.
Again, youtube read my mind. I just watched a video OFFLINE that has something to do with season in there, and then i got curious about sun movement and later, puff... this was in my recommendation.
what i like with these videos is that they are all accurate in the animations, because here the earth doesn't spin around the sun in a real circle but in an ellipse and they added that small detail in the animstions great vid!
Our Earth is rotating anticlockwise looking downward from North Pole side like as the illustration (0:34), when looking along the equator it rotates from West to East. What has happened, on the illustration(3:25),the Earth is rotating from East to West. Is this a quiz finding out the error?
just when i thought that this is only applicable to people on earth's northern hemisphere, it goes to explain how it would look like on other parts of earth's latitude including the southern hemisphere (the other side of the world) and even other planets. Cool!
It didn't. The north pole was pointing up and to the right at Polaris, and then the Earth moved forward 6 months to the right side of the screen and the north pole was still pointing up and to the right at Polaris. Presumably what you mean is why didn't the north pole remain pointed at a point directly above the sun, ending up pointing up and to the left. _That_ would have been a change of direction, and would require a gigantic force to change the Earth's angular momentum to force it not to simply move as its original momentum dictated, i.e. as depicted (far from to scale) in the video. No such force is in operation (it's hard to imagine what even _could_ exert it), so the axial tilt doesn't change noticeably on time scales of a day or year.
I dont think this is accurate, and certainly at least not clear. the single biggest issue is at 3:51 - that suggests that in the southern hemisphere, even though it is summer, it will still be the shortest day of the year. (I assume the reason the summer has the sun at the highest point, in the northern hemisphere, is that being summer means it has the longest days, and the arc therefore has further up the sky to travel - that would remain true in the southern hemisphere). I understand why the orbital eccentricity creates part of the curve slower and part faster, but the video doesnt really explain why the curve goes all the way until it inverts (so that you get a figure eight, instead of a large ovoid). It also doesn't explain if the inversion point is the equinoxes, which I assume it is. I also don't understand _why_ the sun dial is wrong by as much as 15 minutes (they just say it and don't explain it), and so I don't understand why the sun ends up traveling in an figure eight instead of a straight line.
"the single biggest issue is at 3:51 - that suggests that in the southern hemisphere, even though it is summer, it will still be the shortest day of the year." I don't think the video is suggesting that. The December solstice, the first day of summer in Australia, is their longest day of the year. Yes, the inversion point represents the equinoxes, so if you snap the sun at the same time from the same place on both days, then the sun will be in the same place in your sky.
You can see the Figure 8 path in the winter in TX. In spring and summer it switches to a straight diagonal line. What doesn't make since is it's farther away in summer when it's hotter and closer in the winter when it's cold.
The distance is miniscule compared to the effect of how much time each hemisphere spends exposed to the sun and the angle in which light enters the atmosphere, the bigger the angle, the more it gets reflected and loses energy.
Yes, if its orbit were elliptical, the analemma would be straight east to west. If the planet had no tilt and its orbit were perfectly circular, the analemma would just be a point.
In your animation the sun moves the wrong way around. In the northern hemisphere the sun should move from right to left at the top and bottom of the 8 shape.
I still don't understand why its cold in Winter, when the sun is closest to Earth and hot in the summer when the sun is furthest from Earth.. if the light of the sun is hitting us 365 days of the year, shouldn't the its heat also?
The differences in heat is from the amount of direct sunlight the earth gets. When the earth is tilted so wherever you are is away from the sun the earth gets less direct sunlight because the same amount of sun has to cover a larger area. It's kinda hard to describe without pictures, so I would search it up for a better explanation.
I don't understand. Even with your explanation, the Sun would be early only once a year, and late only once a year, but a figure 8 suggests two times a year for each.
WRONG - FAKE video!! 1:the sun moves around the earth using a motor located on the surface of the sun. It uses the never ending fire on the sun as a power source (electricity would not work because of risk associated with cables catching on fire). The earth is VERY big (bigger than New Hampshire and China combined) and very heavy-just think how much the many gallons of the water in the ocean must weigh! There is NO WAY that man could build enough solar panels to move the earth, and what about if it rained? It would mean big trouble, that is what it would mean! Now for you history buffs, during the last ice age (500-1000AD called dark because it was dark in the entire northern hemisphere because the earth was not rotating) man flew to the sun-it was Canadians not Americans, and installed the motor described above. There was some discussion about using wind power-advocated primarily by the peoples of Argentine Patagonia, but the 'which came first; the chicken or the egg' conundrum -i.e. if the earth was not moving, how could there be wind? made going directly to the sun itself (the biggest oil and gas reserve in the world -even bigger than Texas) the least expensive way to get out of the ice age. THIS IS HOW IT WORKS and I DEFY anyone to find a flaw in my explanation.
Where on earth or in heaven did you get this information? You have my attention 🤣. I look I onto all theories. People always try to fly to the sun 🌞 from old stories that I have heard 🤣. It's all everlasting Lies anyway. Another one won't make any difference. Anything possible 😅😂😁

If the Earth is further away from the sun in July, shouldn't it be colder then?
the seasons come from the earth's tilt, not distance from the Sun.
Because the Earth is tilted away from the sun, we have winter, yes?

But the axial tilt means that the fraction of that total energy that falls on the *Northern Hemisphere* increases by 67% - this is more significant and that's why it's the tilt that causes greater temperature fluctuations.

VERY INTERESTING!
You can see the Figure 8 path in the winter in TX. In spring and summer it switches to a straight diagonal line. What doesn't make since is it's farther away in summer when it's hotter and closer in the winter when it's cold.
The distance is miniscule compared to the effect of how much time each hemisphere spends exposed to the sun and the angle in which light enters the atmosphere, the bigger the angle, the more it gets reflected and loses energy.
But what if you’re at the equator?
Jacob Azari , then you get a fairly symmetric figure *8*
Would a planet with no tilt have an anelemma (sp?) of a straight line?
there are no planets we live on a flat plane
Yes, if its orbit were elliptical, the analemma would be straight east to west. If the planet had no tilt and its orbit were perfectly circular, the analemma would just be a point.
In your animation the sun moves the wrong way around. In the northern hemisphere the sun should move from right to left at the top and bottom of the 8 shape.
Today, 22nd of December 2015, is the shortest day of the year
Great video

I still don't understand why its cold in Winter, when the sun is closest to Earth and hot in the summer when the sun is furthest from Earth.. if the light of the sun is hitting us 365 days of the year, shouldn't the its heat also?
The differences in heat is from the amount of direct sunlight the earth gets. When the earth is tilted so wherever you are is away from the sun the earth gets less direct sunlight because the same amount of sun has to cover a larger area. It's kinda hard to describe without pictures, so I would search it up for a better explanation.

Now for you history buffs, during the last ice age (500-1000AD called dark because it was dark in the entire northern hemisphere because the earth was not rotating) man flew to the sun-it was Canadians not Americans, and installed the motor described above. There was some discussion about using wind power-advocated primarily by the peoples of Argentine Patagonia, but the 'which came first; the chicken or the egg' conundrum -i.e. if the earth was not moving, how could there be wind? made going directly to the sun itself (the biggest oil and gas reserve in the world -even bigger than Texas) the least expensive way to get out of the ice age. THIS IS HOW IT WORKS and I DEFY anyone to find a flaw in my explanation.
eddy gee LOL!!!
eddy gee encore!
Where on earth or in heaven did you get this information? You have my attention 🤣. I look I onto all theories. People always try to fly to the sun 🌞 from old stories that I have heard 🤣. It's all everlasting Lies anyway. Another one won't make any difference. Anything possible 😅😂😁
This was so interesting
And we who lived near the equator never experience this solstice =(
Actually, if you watch Minutephysics, you'll know that Dec. 22 was the longest day of the year.
I sun gaze and I see the sun go down more to the left on winter months and more to the right on summer months
