So let's say I have rogue planet the size of mars. I want seasons roughly the the same as Earth and a "sun" that appears similar to our sun from the surface.
How big would the Star need to be? How far away from the planet would it have to orbit?
I also want a moon. I'm thinking maybe 2 bodies of equal size orbiting on either side of the planet would work, but not sure...
Edit - The planet is in reality a space ship with an habitable exterior. The race is capable of artificial gravity and fusion. I Need a sun and moon object in the sky to replicate the appearance of an earth environ on the surface of the ship.
I need to know the minimal distance/size that i could make these from the ship to create the illusion.
