Planetary Orbit and Rotation
Astronomy nerds of tumblr, I have a question. Well, a couple of questions.
1) I know some of the (dwarf) planets in our solar system (Venus, Pluto, Uranus) have retrograde rotation, but that this wasn’t the way they rotated originally and collisions/axial tilt caused the retrograde rotation. Is it theoretically possible for a planet to have retrograde rotation from the beginning of the solar system/spontaneous retrograde rotation?
2). I know Triton has retrograde orbit. Does this mean that if one was standing on the surface of Neptune, the sun would “rise” in the east and set in the west, and Triton would “rise” in the west and “set” in the east? If not, is it theoretically possible for a planet and its satellite to have a combination of orbit/rotation that would fulfill these conditions? What is it?
I’m asking because I’m writing a (fantasy) novel and I think it would be interesting to have that happen, but I don’t want to get *too* implausible.
