Earth vs Sun: the Eternal Chase

[Field physics]

Just something dumb but funny to think about.
Redshift indicates the object is moving away.
The Earth orbits the sun
The sun appears to be red.
So in conclusion, the sun is running away and the Earth is chasing the sun. Lol hopefully that lightens your evening.

Nope, sorry. Krypton was red, and our Sun is yellow. Don't you read the peer-reviewed Superman literature?

The sun close to sunset can look red lol. Especially in areas with a lot of wildfires. https://www.google.com/amp/s/amp.sacbee.com/news/nation-world/national/article252898403.html lol

But ... the sun is white.

That's the point of the thread. The sun is white, but since it is stationary relative to the Earth it gets yellow shifted.

So you're saying our Sunlight's Doppler redshift varies with how much atmosphere it has to travel through?

No, the sun runs away in the evening which is why it goes dark at night. (Then it hides under the turtles.)
