Isn't it more of a blue shift / red shift situation, rather than scattering?
No, it's definitely atmospheric scattering. Blue and red shifting occurs when interstellar objects accelerate towards or away from us near the speed of light
Imagine the horror if the earth accelerated at such extreme speeds on a regular basis.
How do you know it doesn't? Science.
Or rather imagine the horror if the earth accelerated at such speeds DIRECTLY TOWARDS THE SUN 😬😂
Not for long at least...
Okay, class. We're going to watch NOVA today.
"Earth: God's Baby Rattle"
There is a very small amount of red shift. If you were standing on the equator watching a sunset, then your radial velocity relative to the sun is only ~461m/s. So the green light from the sun 550nm would be red shifted by +0.0008nm. That little red shift wouldn't be noticeable. However, as the sun sets there's a lot more atmosphere in the way, which scatters blue light more than red light (Why the sky is blue). Also in a sunrise you are moving towards the sun, so sunrises would be blue! :P
Are you sure those numbers are right? The proportions of 550nm/0.08nm and c/461m/s are very different.
Oops you're right missed a few zeros.
