The Sun’s surprising movement across the sky - Gordon Williamson 

I had a globe with that figure-eight thing on it, but I never knew what it was.

Why my brain doesn't seem to understand this..?

Really tough to visualise.. I'll have to watch again

If the Earth is further away from the sun in July, shouldn't it be colder then?

Tonight is the longest night of the year

Published on the longest night of the year...well played Ted...well played.

Axial tilt - the reason for the season!

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.

First TED-Ed video that was actually pretty hard to understand... +Ted-Ed I want more videos like this!

ted ed really has answers for every question you've got!

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.

"But there's a twist" Get the pun?? XD (right after, the narrator talks about inclination)

let these "the earth is flat" psychos explain that away. or they'll just ignore all of it and say its all lies. lol

0:00 - 0:05 the sound when you know you are about to get a shit ton of knowledge..

Woah, this animation was so pwetty .w.

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.

OMG that's what that figure 8 is on my globe!

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 🤭

One reason why I liked the video: The song actually sounds like a Universal Sandbox 2 relaxing song/sound.

It was great to me. I really heard all this the first time. My teacher never explained like you did. Your explanation is way better .

Here in Australia it's currently summer, and the sun starts to come up at 4am and doesn't fully set until 9pm.

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.

Great video! Loved the animations on this one :)

a ted-ed video that isn't designed to feed people's anxieties - hooray!

Please add closed captioning or subtitles for the deaf and hearing impaired audiences

TedEd...you guys are awesome!

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?

Would it still do the analemma if you took the pictures at exactly solar noon every day? Or would it just go up and down?

Stationary Earth, it's the that complicated

3:52 Relaxing aussies.. lol. Nice animation throughout.

Thank you. You always help me

Brilliant gem!

I am still confused.

I thought TED should give more reliable info. "8"-form is firstly due to axial tilt. And eccentricity just gives some asymmetry to this "8"

Did anyone else keep thinking of the Van Gelis tune 'Albedo 0.39' when watching this?

Thank you! After more than 30 years of existence, I finally learned what causes seasons.

Richard Dawkins - The magic of reality"

Hi, How it reaches its farthest point in July, and still hot? isn't it supposed to get colder??

VERY INTERESTING!

First ever comment 😜😜

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?

The sun and moon follows me everywhere I go

This is the greatest video online. The reason the Internet exists.

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.

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.

this makes more sense on an azimuthal equadistant map.

It looks like a tilted infinity symbol

I live in Australia. What's winter?

thats awesome! i knew all this stuff except about the 8 and the earths orbit and how we move faster in january

But wouldn't that change the equator?

Isnt aphelion pronounced "ap-helion" not "affelion"???

aaah this was such a good one ^^

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 👍

is analemma in mars same as in earth? if isn't what it's look like?

can I please get to know the name of the soundtrack?

I much prefer spring & fall since it's warm in them.

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?

Make it simpler to understand with some 3d or more visuals!

This was a great chemistry video

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!

So fantastic video. So many things that I never heard before

I thoroughly enjoy these videos, especially about celestial bodies and roman times

i learned nothing from this video... because it is way to complicated for me XD and i love this channel :)

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?

great video

Amazing.

so in australia how ?! thanks

Nice art style

Thank you!! Great content with good animations :)

What would an analemma look like on Uranus?

The sun goes around the earth you'll see

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.

And we who lived near the equator never experience this solstice =(

amazing video it makes me want to learn astronomy instead of medicine what is better?

brilliant ! movement of sun animation by gordon williamson is totally brilliant ! thanks.

This is fantastic!

But the htraE is diamond shaped :/

when is it a teardrop

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.

Would a planet with no tilt have an anelemma (sp?) of a straight line?

It seemed simple, then complicated, then simple in the end.

Hello Ted-ED how's it goin? :)

I just got scienced the f**k out! Still feel a little dizzy...

The Earth is flat. But Uranus sure ain't.

I still don't get the figure 8

That still did NOT , explain it's path as a figure 8.

Aphelion is not pronounced afelion, it's pronounced ap-helion. It is the helio-centric apoapsis of an orbit - i.e. the root words are apoapsis and helios. (And Apoapsis is pronounced apo-apsis.)

This explanation is funny. You guys accept any explanation and say "wooooooow". Demand the truth

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?

Silly, primitive humans drawing figure eights on their maps, why didn't they just invent a GPS? DUH!

I have been expecting video's about earth orbital rotation. Thanks a lot for excellent explanation and fascinating animation. Background music is cool...

Beautiful.

the 78 ppl who disliked the vid probable were upside down and thought it was the like button

So summers are longer and winters are shorter because of gravity. But I like winter

But what if you’re at the equator?

stop lieng the earth is flat

Gee, I wish the video actually explained this. It's not clear at all.

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

Excellent!

this is where the infinity symbol comes from
