Astronomy Question for Fictional Writing
Hi there- I am wracking my head trying to figure out something that is probably astrotomically impossible, but would love to somehow make it work for a story I am writing. I love the idea of the night sky specifically altering in color based on the prominence of two celestial bodies, one red and one purple. Ideally i'd love to have parts of the year where one is more prominent than the other and vice versa, as well as times where their orbits are more similar, and the light from them mix together, perhaps even causing eclipses. I also love the idea of a calendar system based around different points in their orbital patterns (holidays denoted by a predominantly red sky or purple sky, colorless or an equal mix).
I've been playing around with rotation patterns for hours and just can't seem to make it work. The biggest issue is that I want it to happen at night so in my head they act as moons but then they wouldn't produce their own light. I also tried rotating them around a star in order to produce that effect but I don't know if that would work either. In the end I would love to have the image of one or multiple moons in the sky depending on the time of year and a shifting color. If anyone has an idea on how this could math out even slightly I would be so appreciative. Thanks yall.
