I am seeking to temporarily trap my protagonists on a wasteland. The kind I wanted to create was an icy planet that doesn't experience day or night, just a constant state of moonlight. I suppose th...
I'm not sure if this question belongs here or over on Physics Stack Exchange. The Earth and Moon are unique in the Solar System in that the Moon is a significant size compared to the Earth, at 1/4...
The singularity has occurred and it wants an off-site backup. How deep should we all bury the lunar datacenter to be comfortably safe from radiation, cosmic rays, etc., while not causing cave-ins ...
Anchor one end of the cable to the side of the moon that faces the earth. Drop the other end of the cable to earth so that it drags along the ground. The earth's gravity and friction contributes a ...
Inspired by https://worldbuilding.stackexchange.com/a/30400/3434 Related but too different in details for answers to apply Why not build a space elevator starting from the moon? As answered in th...
We have all heard about the idea of space elevators, a cable so long that it literally reaches into outer space, to be used for launching payloads cheaply into Earth and interplanetary orbits. Howe...
Is there a way for the moon to be seen at every point during the daytime? In my world it is day all the time so they have a rough concept of months, years and days. To solve this they could have mo...
As the legend goes, Coca-Cola was planning on shooting lasers at the moon to project their logo. Unfortunately, the FFA said no (they didn't want planes to be blinded). I haven't been able to confi...
Background Several hundred years from now, humans have successfully terraformed the Moon. It has become a fad for the rich and powerful to have exotic residences built in exotic locations. The ri...
I'm trying to picture life on a planet sized moon of a huge planet in a one-star stellar system. It would be tidally locked, which could do some interesting things. It has an iron/nickel core for t...
DISCLAIMER: This question was closed on Astronomy Stack Exchange as off topic, so I'll try my luck here. I'm trying to understand the climatic effects of the far future scenario of an Earth-like p...
Definition: Interlunar adjective Of or traveling between moons. I'm (as far as I can tell) inventing the term interlunar to describe travel between moons in a single planetary system. Travel b...
For my Science-Fantasy WIP I am considering using a single artificial planet (roughly the size of a Dyson Sphere) and its moons (of which only three are large enough to exert any real influence) as...
I am a staunch believer that any near-future permanent colony on the Moon or Mars should be built underground, at least the living spaces, due to the harmful effects of radiation. What is the grad...
Let's say that in my planetary system there is a gas giant around the size and distance from the Sun as Jupiter. I need the planet to be similar enough to earth to be able to be inhabited natural b...
In 2053 a manned mission to the moon, using seismic sensors, discovers that it is not a natural satellite*. The moon is actually an egg of Vespula ludicrousmegagiganto. Note that the name is not ...
Tidally locking a rock or metal moon isn't too hard and the understanding of how a solid moon behaves while tidally locked is relatively well understood. However, can a water moon be tidally locked...
Let's say that a gas giant (around the same size and distance from the sun as Jupiter) has a moon that supports life. The moon is around the size of Mercury (if this is too large please let me know...
I have a story where a powerful outside force killed (next to) all humans on earth some decades ago. The way I want to build it is that it required that the human outposts on the moon to die as we...
I have a group that's building a moon colony. The final end goal is a self-sufficient colony of at least 1 million humans. They have access to one million metric tons of lift per week at nominal ...
I am an awesome, famous, self-made billionaire - I started with a mere \$300 million and amassed that into over $4 billion in only 40 years (an amazing 6.75% return). Everyone loves me - the black...
For those (readers) who have seen the blockbuster movie titled I, Robot (2004 film) there is a humanoid robot who prefers to be called Sonny: Clearly this implies that Sonny is different from the o...
According to Wikipedia and this answer, the Moon is orbiting the Earth at a distance around 20 times greater than than the point where it would break up. As far as I can tell, that means in a ficti...
Okay, so some space miners fly into space to get Helium-3, and then fly it back to earth to sell to non-space people. Flying into and off the earth is rather expensive, so they want to simply take ...
It is simply a matter of time before human colonized our natural satellite and the red planet, so how to lay roads that is similar to ours on lunar and Martian soil? (For now suppose we are plannin...
I am considering a world with a very long light/dark cycle. However, I would like some natural method of measuring out a "day-like" period of time. Could an object with an orbital period of aroun...
My moon is the basis for a fantasy setting, but I just can't bring myself to abandon science and say "a wizard did it." I want to make the months and seasons realistic, and I want to find a way to ...
The idea is- as the moon is passing over, the pull of Earth's gravity on immediate area surrounding the spacecraft somehow temporarily cancelled out (still working on the how) and the craft falls t...
In many series (Elder scrolls for example) they have a huge moon. It is rare though when they explain how it can be larger. There are only two choices both of which couldn't work; One is to brin...
We like the moon. It's close, you can see your home from there, low gravity well, so you get easy mass drivers to orbit for fleshing out your spacer economy, plus you can do fun things in pools. ...
Here on earth, the moon is this big white thing that lights the world and hangs in the sky. Every culture on the Earth has incorporated the moon into some of their legends. Sometimes as a woman, so...
I'm currently heavily revising a story which is largely set on a habitable but not exactly hospitable moon of a gas giant orbiting on the outer edge (or just beyond) of the habitable zone around a ...
The internal structure of the Moon is different from that of the Earth. There are neither volcanos nor many moonquakes. Using early 21st century technology, could we dig a vertical mine shaft all t...
If there's one thing that solid celestial bodies have, it's dust. Dust plus water is mud. Mud plus heat is brick (and recoverable water vapor). The heat can come from a reflective solar array. Easy...
I've always been curious whenever I heard the mother wererabbit sings a popular folksong to the young, there is a particular line in the lyric that seems to puzzle me. It goes likes this: "up up a...
Let us assume that we have a moon with a reasonable iron core enough that it can retain atmosphere, (as per this question), now let us further assume that the people who settle on the moon are shor...
In my world, Earth populated the Moon. Even if people are concealed in stations they got to go out from time to time (to explore or repair things that robot can't). My question is: Is it possible...
Setting: we have a fantasy world which is a planet with much of the same conditions that can be seen on Earth, but with the difference that it is orbited by a moon with a mean diameter of 3 500 km....
It is said that the Moon plays a significant role on stabilizing the obliquity of Earth (or call it the axial tilt). Without it, the tilt of the planet is subject to great variations causing unpred...
So some aliens come, put everyone in space suits, and drop us one the moon. The aliens are super smart, and the space suits have enough air for a year, and can't be damaged easily, and only upon fr...
In Dungeons and Dragons lore, there exists a construct called the cosmos used to define a variety of planes of existence. One of these is the Material Plane, on which our normal reality is found. ...
So, for reasons which may or may not pop up in a later question of mine, I need to light a small Moon-like moon on fire. Well, sort of. See, I need a small object capable of emitting a lot of ligh...
Recently I had an idea for a world setting. A large part of this world focuses around a habitable satellite the size of Earth orbiting a Super-Jupiter. The fact that it's a moon is pretty integral ...
Can the gravitational pull of Earth drag the Moon into Earth's atmosphere? Likewise, can the gravitational pull of the Sun drag Earth into the Sun's atmosphere? If that can happen, what will happen...
Is it possible for complex life to exist on a planet with no tilt and no moons, and be so close to its sun that the equator would be far too hot to cross on foot and still survive, and its poles fa...
See this question for further details I also know how unlikely this situation is, so please refrain. From telling me "it won't happen." Jupiter is sent on a spiral into the inner Solar System. Bo...
On a tidally locked gas giant moon (which is otherwise earth-like - see this question for pictures) how would medieval sea navigation techniques differ from Earth? I presume that compared to Eart...
Imagine a tidally locked gas giant moon, which is otherwise earth-like. One side of the moon will have a huge planet constantly hovering in the sky (24 hour day/night cycle with a Jupiter-sized pri...
