This Is How The Sun Moves In The Sky Throughout The Year

If you photograph the Sun at the same time every day, you get a bizarre figure-8 shape: an analemma. Here's why.

But the Sun doesn't appear to simply rise and fall in the sky in a symmetric shape. Sunset and sunrise times vary throughout the year. The Sun reaches its highest point at a variety of times as the seasons change, not merely at noon every day.

Here’s a fun fact- it takes 24 hours for the sun to reach the same spot in the sky the next day, but it only takes a

This is usually false b/c the sun's position in the sky changes from day to day

The sun reaches its highest position in the sky at the same time every day.

1 day is exactly 24 hours. 1 sidereal day is 23:56:04. That’s my only contribution in this post. In exactly 24 hours

Can you provide one example where this is actually true? I can't think of one

He doesn’t mean path or “location”. He means time at which it reaches its zenith. It’s true because as the earth orbits

Are you saying it's 24 hours from zenith to zenith? that's also not true

ryebrye

Nope. The point isn’t claiming any *precise* location (or time). The point is that the difference between the apparent

I'm still not sure what you are trying to say.

Yeah, you’re still thinking about this in terms of precise timing and location and that’s not the point. The point is

Do you know the difference between a “solar day” and a sidereal day”? This is what he’s taking about. A solar day is

I was just pointing out the difference between a day and a sidereal day. That’s it.

I'm confused. Doesn't the sun change positions in the sky slightly every day?

So do the stars. The earth tilts a bit every day.

You mean to reach the same azimuth, right? Like, sure, the elevation can vary

RoboKayne

That also varies day by day

ryebrye

Oh no. I find these things very hard. Literally nothing about celestial geometry

RoboKayne

Yes

Proof the earth is flat….

What is so "fun" about that fact?

Some people enjoy learning random new things and seeing how it connects with other things they knew and displaces stuff
