I am writing a novel where a habitable moon orbits a purple gas giant. In looking here and elsewhere I'm finding it incredibly hard to get a sense of the elements-breakdown of elements that would b...
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...
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...
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....
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 ...
The Hegemony is in need of superconductors for their fleets of stratospheric craft (stratocraft for short) as well as many, many, many other applications. I recently read metallic hydrogen is a the...
"The planet moves." Inspired by this link in a comment from Gryphon here, I also see the concept in this question. We've colonized the moons of Jupiter adjusted their orbits to our satisfaction (...
Gas giants can generate heat via the Kelvin-Helmholtz mechanism. It's oft-repeated that Jupiter actually generates more heat internally via this method than it receives from the Sun. Scale this mec...
For this question, I was inspired by the following image of the "Jupiter Abyss": What I want to know is, can a Jupiter-like gas giant have thousands of giant black storms, kind of like what I've...
In my world, humans live on a moon of a gas giant that has extreme weather conditions. They also: have crystals that can store energy. possess the ability to make floating islands (on which they...
if it takes the moon 6 months to pass through the gas giants shadow? Assume it is distant enough to not be tidally locked. The gas giant is 112.5 AU from the star. The star is 55 solar masses. ...
This is a progression from my first question, here (if this is too similar to my original question, please let me know of a better way to address this, as I am not getting the answers I need on tha...
We lived through loads of questions regarding aquatic races, so buckle up, I am going to gather some ideas around insectoids. The homeworld and race This race lives on a planet which has lower g...
I have the feeling the answer to this will come down to ''impossible'' but let's ask anyway to be sure. We know gas Giants have no solid surface and if you tried to land on one you would fall int...
I've begun the laborious (but fun!) process of putting another world together. Known constraints include: Habitable, (super-)Earth-sized, tidally-locked moon to a gas giant; the giant, where vis...
I seek to build a habitable moon of a giant planet, thus I looked at the Rouche Limit Equation to figure out how to get the biggest possible Hill Sphere for my moon to exist in. $r_H = a(1-e)\sqrt...
Being new, this is my first question. I've read some other posts that gave me valuable insight, but I still have some questions. First, some specifics: Star: red dwarf. 80 x jupiter mass. 3 bill...
This is an edited hopefully more focused version of a question I asked a while ago. I made the mistake of asking too many questions the first time so I'll try and be a bit more focused here. I d...
A spacecraft enters an unnamed system and spotted a gas giant with a pulsating planetary ring, it glows bright intermittently. What natural phenomenon could be responsible for such brilliant displa...
I know of the conceptualized "Sinkers", "Floaters" and "Hunters" that Carl Sagan and Edwin Salpeter of Cornell conceived of - as possible life forms that might inhabit a gas giant. At the time they...
By a stable orbit I mean not getting ejected by the other planets or ejecting them, Let's create a scenario where Neptune occupies an orbit in the asteroid belt at 2.76 AU, Ceres average distance f...
Here's what I've come up with: The star: A main sequence star, roughly a sol analogue Younger than Sol (say 3-3.5 billion years old) roughly the same starting mass as Sol, but has had less tim...
Making the following assumptions: 1. The three moons of the Gas Giant are safe enough distances from and massive enough not to pull each other apart or send themselves careening into the void. 2...
So, in my research and preparation for the question I asked immediately before this one, I was introduced to the concept of "fluffy" gas giants, gas giants with significantly lower density than wou...
I fear the math involved is beyond my capabilities on this one. I have what I consider to be more than a Layman's understanding of the physics involved, and I believe I can follow the math well en...
The selected answer on this question provides an extremely good, and detailed, description of what is generally accepted to be the main (only?) way a terrestrial planet can form, i.e. through accre...
I'm writing a science fiction story set on a moon orbiting a gas giant. I want to understand how the world's day night cycle would appear from its surface and how the world might be affected by thi...
Science-based answers, please. Key points: the main concern is radiation protection for sustainability of human life (and accompanying plant and animal life ecosystems, whether earth-like or n...
Brown dwarfs are celestial bodies in the gray area between planet and star. They're huge, gaseous, hot compared to planets, and come in all different kinds. (1) Is it possible for life to develop...
A futuristic entrepreneur wants to start a cruise line company and needs to build a cruise ship that will not only float on a gas giant, but be habitable throughout a 7 day trip (for the uber-rich ...
What additional difficulties might the inhabitants of a gas giant moon face when attempting to launch spacecraft beyond their moon's orbit, especially beyond the planetary system? I presume that th...
I was amazed when I learned that Jupiter rotates on its axis once in only 9.8 Earth hours. (Yes, you can call me uneducated!) What if the rotation period was 24 Earth hours? What would change in th...
BACKGROUND The world I'm designing currently has a gas giant of the type known as a hot Jupiter orbiting close to the sun and causing solar flares. I would like the inhabitants of my Earth-like wo...
I want to create a gas giant planet. The parameters I would like for it to have are: It should have a large layer of gas within its atmosphere that living creatures including humans can survive an...
Malgrovian gliders inhabit the middle layers of the atmosphere of Malgrov, a gas dwarf. They spend most of their life gliding, preying on giant balloon-like floating lifeforms. When they get olde...
A previous question's answer established that naturally occurring positrons could be gathered through positron-emitting isotopes. I've started looking into means that these isotopes could be gather...
I am imagining a special ecosystem on a rogue planet (a planet that wanders throughout space without orbiting a star or other heavenly object) but I would need your help to fill in the gaps and rea...
Ghyesh is an Earth-like habitable moon that orbits a gas giant in a system with a sun significantly larger and hotter than Earth's. Both the gas giant and the sun emit an equal level of heat to the...
I was thinking of writing a story and had the idea of having a society exist on the core of a gas planet. The core would be similar to earth with a breathable atmosphere similar to ours above it bu...
I've already asked a similar question but i'd like more details. This moon would be orbiting around a saturn like planet without rings. The host planet would be located in the habitable zone, allo...
Is there a limit (and if so, what is it) to the size (mass) of terrestrial planet that could be "captured" as a moon by a migrating gas giant? I'm writing a novel where a colony ship crashes on su...
I'm looking to build a "twilight" world, where days are like twilight even when the sky is clear and nights are...very dark. Cloud cover might be able to turn day to an early night. I do envision a...
So I want a large power source to heat my new real estate on the Jovian moons. I create a micro black hole (MBH), maybe a few kg, maybe more and drop it into Jupiter. I expect the following to h...
Would it be possible for a gas giant to have differently colored hemispheres? E.g. the northern hemisphere appearing blue when looked at, while the southern hemisphere would appear brown? (or any ...
I was wondering about a setting where a moon orbiting a gas giant can sustain human life on its surface, i.e. with nearly identical conditions compared to Earth (e.g. size, gravity, mean temperatur...
Based on my recent series of questions: here and here. The giant known as Jupiter has moved to the inner Solar System and Earth and Mars have become it's moons (despite all the odds). The moon of ...
In the story I'm writing, a gas dwarf (named Eden) is discovered in a triple star system. Its atmosphere is mainly oxygen and water based, and its gravity is slightly higher than Earth's. Unlike o...
Worldbuilder in dire need! I'm trying to figure out the eclipse length of a habitable Earth-like moon that is rotating around a gas giant. The story that I work on is centered on the Earth-like mo...
Jupiter is a terrible place to be, but for a number of artistic reasons, I'd like to have my story take place there and only there. "Mining", or resource extraction by any other name, is the usual ...
