What colour is the sky on other planets?

Click For Summary
The color of the sky on other planets is influenced by the chemical composition of their atmospheres, the type of nearby star, and the atmospheric density and depth. Factors such as the angle of sunlight, time of day, and presence of clouds or particulates also affect sky color on Earth. Different stars, like red or blue ones, would create vastly different environmental conditions. Additionally, the temperature and state of atmospheric components, such as droplets or dust, play a crucial role in determining sky color. Overall, the interplay of these elements leads to a diverse range of sky colors across different planets.

I imagine it depends on the chemical makeup of their atmospheres.

And the 'color' of the star nearby and the distance to that star, and the depth and density of the planetary atmosphere, which would be functions of the composition and planetary mass (local gravity).

Our atmosphere appears blue, or yellow, or red, or white, or grey depending on time of day, angle of the sun, clouds or clear, dust (particulates) in the air. Our sun is a 'yellow' star, but it could have easily been a red star or blue star, and we would have a different environment, either too cold or too hot. The atmosphere on Venus would look very different.

Edit/update: I'd add temperature of the atmosphere, which be included in the state of the components as mentioned by sophiecentaur.

And the state of the components (e.g. are there droplets, crystals or dust ) in the atmosphere.
 

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
