Science in Science Fiction: orbits and artificial habitats
This article on satellite orbits in sci-fi is part of the Science in Sci-fi, Fact in Fantasy blog series. Each week, we tackle medical or te

“Standard orbit” is a phrase used frequently in a popular sci-fi franchise. Problem is, there is no such thing as “standard orbit.” But that’s okay. This is not a sin… maybe someone will define a “standard orbit” for spaceships one day.
Biomedical scientist Philip Kramer shares tips on enclosed ecosystems and life support in science fiction.
The Expert: Philip Kramer
Closed Ecological System (CES) is a broad term that encompass any self-sustaining and closed system in which matter does not leave or enter. These artificial habitats can be built in space, underground, or underwater, but no matter where they are, chances are they are closed for a reason. Whether it is an underground bunker in a post-apocalyptic setting, a distant planet in the early stages of colonization, or a spacecraft carrying the last remnants of humanity, the environment outside is not hospitable. To ensure long-term survival, the occupants must maintain a well-balanced air and water system, a continuous food supply, and a reliable source of energy.
Apparently it makes me a “super villain” and an “evil scientist” to want to use a big big magnet to try to pull the planets in our solar system out of orbit. Personally I think it’s just good old fashioned scientific curiosity but whatever
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.

they call it “orbiting” cuz u ain’t never gonna hit that đź¤
It was doing that before we existed and it will continue to do that after we no longer exist.
