What does a neutron star "look" like Hi, I have some questions for a scifi story I'm working on. First, what would a neutron star look like? What color are they, and how bright do they tend to be? By look like, I mean both seen from a theortical planet surface orbiting one (or mabye it would always have to be far enough away that it would just be a point since they are so small?). And from a spaceship flying through the system looking out a window? In other words, how luminous and what color are they? The other question is with a binary star system. If you wanted to have a planet in orbit in a binary star stystem that had roughly the same conditions as Earth (size and temperature), would the planet have to orbit around both stars? Is this a assumed to be a general property of binary stars, that sattelites are in a large orbit around both, or would some paths take the bodies in between? For that matter, would the orbital plane of a solar system around a pair of binary stars likely be in the same plane as both stars? Or would it be around the center of mass between them? Or does EVERYTHING just orbit around one of them, with the second star acting more like a very large planet? Or something else entirely? And finally, how close are the two stars in a stable binary system generally? Thanks!
