I'm interested in giving a conworld moons orbiting in a Laplace resonance, like the inner Galilean moons of Jupiter. Here are the constraints I believe hold for moons in a Laplace resonance (orbit...
Is a colony on earth's moon must be deeply underground to ensure more natural gravity (by getting closer to its core) as well as more natural heat? By natural heat I mean "without the need of arti...
Could a planet with the size and characteristics of the Earth orbit a gas giant and would the earth-like moon be able to maintain its orbit if the gas giant went rogue and was launched from its hos...
I'm building an earthlike world that has a moon orbiting a gas giant. Is it possible for the moon to always be between the planet and the sun? Also, is it possible for a moon to rotate around its o...
A hypothetical scenario I'm batting around in my head is a Habitable Gas Giant system consisting of a roughly Saturn sized body orbiting a sun like star at a comfy goldilocks zone distance. Orbitin...
In my world a moon is reached and colonised but only in space stations for a long time. They gain the ability to reach the surface and then story happens. It needs to be something that can be bypas...
My world is a satellite of a gas giant. It has an atmosphere and is mostly covered by water (the percentage of water to its surface is somewhere in the high 80s-low 90s). Its rotation period is 28 ...
I am working on a world where an event, like a celebration, occurs during every lunar eclipse. I would like to have lunar eclipses occurring more frequently--maybe even once a month--in order for...
Let's say you have a planet about the size of Earth. It has three moons, each roughly the mass of one-third of the Earth's moon. Would this cause tides of different magnitude than those on Earth? A...
I am creating a fantasy world in which Earth has a second moon with an orbit between Earth and the current moon. The orbit of this new moon is faster because it's closer to earth. I'm not much co...
The moon is similar to earth but orbits around a gas giant, the sun has ended its life cycle and so the only energy received on the moon comes from tidal interactions heating its core. On earth an...
(This is the third in a series of questions, starting with Moved into further orbits to protect them, how much damage do Earth and Moon take when the Sun expands? and How soon does the Earth's surf...
Imagine a big Moon base situated under a dome. Big means under the dome there is a small city with buildings, streets and ca. 30,000 inhabitants. The best analogue in the movies would be the Ceres ...
If you found out a way to produce a smooth icy surface on an ice moon like Ganymede, Enceladus, or Callisto, what kind of challenges would someone face if they tried to start ice skating? I figured...
I am interested in the idea of a moon orbiting only the southern pole of a planet. Could it theoretically be possible (though unlikely) that a moon would, for instance, orbit a planet parallel to t...
If we moved Enceladus (not Europa) into Earth's orbit (ignoring the plausibility of it), and gave it a breathable atmosphere, what effects would it have on the Earth? How would it affect us?
Short version A far future catastrophe burns/melts away large chunks of the Earth and Moon. For reasons related to my story's fantasy elements, the remains of the Moon have about one fifth their or...
Given current capabilities, is it possible for a missile launched from the surface of the Earth to impact the surface of the Moon? I would imagine the same "rocket" used send stuff to the ISS coul...
So we have a Super Earth of ten Earth masses, just on the threshold, and it has three Mars sized moons (so a mass ratio of 100/3, more than Saturn Vs 3 Earths). They go 40,000km, 100,000km, 250,000...
In my book which is set in the near future (some hundreds years from today) the mankind has mastered interplanetary travel. Although the travel to let's say Pluto is possible, it still takes severa...
Imagine a gas giant as massive as Jupiter has a enormous planetary ring which will expand and contract throughout its orbit around a main sequence star. Then there is a moon as massive as Mars an...
I have several stories where I've wanted a moon in some weird orbit that is not allowed by orbital mechanics. In the past, I've had to change stories to bow to physics. Today, I had a thought whil...
It appears that there are gas giants in habitable zones of stars, and likely some of them should have moons that are big enough to have an Earth-like world, so that part should be plausible enough....
I am recalling the Space:1999 nuclear waste containment explosion; this has been criticized because such an explosion would have actually destroyed the moon. I am curious for events that could happ...
Mining on the Moon, and by that I mean removing mass from the Moon, I believe will affect the equilibrium of the planet and cannot be compared to mining on Earth. When we mine on Earth we don,t rem...
First question: if you melted Europa's ice, would there be any land? Second question (assuming the answer to the first question is no), how much water would you have to remove after that in order ...
In our world, a solar eclipse is visible from the planet a few times a year, in certain locations. However, a total solar eclipse that can be seen across the planet generally happens every three or...
The moon is made up of a substance called warpstone. This rock is solidified Mana compressed into physical form. Pieces of the moon will sometimes fall to earth, which contain magical properties an...
I'll need to give some background to this question. I'm interested in the idea of a densely inhabited star system, and having large exomoons is one way that they can all orbit roughly at the same p...
This is more for fluff and illustrative exotica, but I'm keen on an idea where my new world has a moon that orbits elliptically, but has a fast inward close orbit followed by a longer round trip th...
I'm trying to figure out what weather patterns and geographical conditions would exist on a habitable moon that is tidally locked to a much larger planet/gas giant. From my research, I was able to ...
Imagine one day the moon suddenly transformed into a colossal elephant's foot and we need to get to the moon to obtain sample... Could it be done using modern day technology to mine the uranium for...
The planet is 10 Earth-Radii, with a 1 Earth Gravity value. It is a habitable planet. It has a thin atmosphere. It also has 3 moons and a ring system. The moons are rather large. The largest one i...
Would anyone be able to check some math/ let me know if I'm thinking of this the correct way? I had an idea of the moon appearing basically stationary in the sky, but in fact it orbits just faster ...
Long ago, I made a post with a scenario on how planet Earth would be affected if our moon were the size of Mars. But I've decided that it be more reasonable if our moon were closer in size to Tita...
I am curious that if there were a gas giant sitting close to a red dwarf with an Earth-like satellite orbiting it: How could we determine the way the planet appears in the sky and the way it i...
I've got a lunar colony that was set up to be self-sustaining before a collapse of life on Earth. The colony has survived on its own for several thousand years through a period of technological reg...
NOTE: If there is anything about this question that needs clarification or editing, please don't hesitate to let me know in the comments. Get ready, because you're in for quite a ride. I have t...
Thanks in advance for any input you can provide! I have a moon called Vieneo http://www.risetvp.com/Vieneo which has some geological modelling of faults and epicenters over some range of time: ...
If this hypothetical moon were to come to exist between the Earth and Moon, how long would it survive? And could it transition to the moon's orbit, as a subsatellite? To clairify, this scenario is...
In the 1960s we were disappointed to find that the moon is a pile of dust and rubble with no easily accessible valuable materials. Well, we kind of knew it before that, but we weren't sure. Anyway,...
Background: The moon has been selected as the base for human space exploration. Rather than ship tonnes of material out of earth's gravity well, interplanetary spacecraft and space stations will be...
Would abnormally high levels of cobalt on a moon cause it to appear blue to those on the planet it orbits?
On a planet with a geostationary moon, how can I determine the position in the sky of the moon depending on the position on the planet surface? For example, Pluto's Charon. The moon wouldn't move ...
Hello I imagine this is a pretty straightforward question, perhaps already covered in another post, but I wanted to get extra perspectives and options for achieving this type of planet or moon. So ...
We have at most 100 years to abandon earth. The 10-km asteroid which killed the dinosaurs has hit the moon head-on instead. As a result, the moon has slowed down and it's orbit will decay by 400,00...
I'm attempting to figure out the orbital physics of a system that has a habitable body that has intense periods of waxing and waning sunlight. I've come to the assumption that the best body for thi...
My story takes place on the moon of a large gas giant planet. I have been trying to decide on a way for the moon to be as Earth-like as possible, but I have now decided to ask the community for hel...
Looking most specifically regarding the moons around Saturn, Jupiter, and Uranus. I've been unable to get a concrete answer on this through various sources. I've actually read several articles brie...
In my novel, the many moons of Jupiter and Saturn have been colonized, but I'm running into some logistical problems - namely, waste disposal. My first instinct was to dump it on-moon; while this ...
