So, I've got a planet that's basically a junkyard. It's just one big junkyard. People from various space-faring societies dump all the crap there that they don't want to deal with. Derelict spacesh...
Planet: Xibalba (Mayan Hell) Tidally locked planet around a red dwarf that is very active with solar flares being a daily danger. The habitable zone around the planet is made up almost entirely ...
Assuming we want our sun to last as long as possible with a similar luminosity and assuming we value life over lifelessness can and should we manipulate the sun, gas giants and ice giants to that e...
I am searching for a software capable of creating any planet ( like universe sandbox) with the ability of shaping the landscape and adding tags to any coordinates I wish to in order to represent ci...
1 degree of latitude = 96.57 km. Equirectangular projections. (Yes, I need to revise the polar regions to make sure they don't get squished.) Obliquity of Jasmi: +31.1 degrees. Radius of Jasm...
So I would like a coloured sky in my world, but I want it to be plausible. I'm not so good at science and the like but I've been doing a lot of research. If crystal-like asteroids filled with col...
I'll try to keep this question as concise as I can, but I'm not great with technical jargon, so a simplified answer would be greatly appreciated. Here's the set up: I have binary star system with...
Can life exist on a asteroid? If the asteroid can sustain life, when the asteroid crashes on a planet can life survive going through a atmosphere and landing and then living on a earth-like planet ...
Could a planet's axial tilt change a meaningful amount (what is needed to make inhospitable biomes even more inhospitable: hotter dry hot desert, colder north) over an extremely short period (~100 ...
Imagine a planet - henceforth Planet X - that is orbiting very close to a black hole. The space-time distortion will be very high there and according to the theory of relativity, the time there wil...
As the title says, I'm wondering if a species could theoretically boost an asteroid near a planet for easier mining access. If this was to accidentally crash into the original planet could a habita...
I was thinking about people who once told me that I must feel the rain earlier than them (I'm tall). So I thought of a world where the rain falls so slowly that the humans of different size living ...
Let's say humankind terraforms Mars aggressively, increasing the planet's mass (and gravity) to Earth-like levels and causes its core to produce a significant magnetosphere. For example, perhaps th...
What can cause water to be foam-like, in lumps, but still liquid? Something similar to goo (jelly like but liquid and opaque)? I have a planet and such kind of water, which is drinkable and the te...
As many here likely know, one of the factors that make both Mars and Venus uninhabitable to humans are their lack of a magnetosphere to keep solar winds out. In the setting I am working on, I want...
How can I make a colonizable planet/moon that receives intense UV/x-ray radiation on parts of its surface while receiving much less on the rest of it? The most obvious way of doing this is to have...
Assuming that some future civilization of hyper-advanced humans, or aliens for that matter, had the technology to reshape the solar system so that there were several habitable planets the rough siz...
Bryan Konietzko (you know, one of the guys being Avatar The Last Airbender and The Legend of Korra), is working on a new project called Threadworlds, which takes place in a solar system that has 5 ...
In a Rocheworld scenario where two planets are tidally locked and share an atmosphere, but where both the planets are so small that their gravity is very little (as low as one of the dwarf planets ...
I'm working on a story set in a planet of permanent dusk/dawn, and with a dark side that never sees the light of sun. I know that a planet tidally locked to its star would (roughly) look like this,...
The planet in question is this one. Approximately three quarters the size and half the gravity of Earth, an atmosphere 25% as dense as the Terran one which mainly consists of Nitrogen with small pe...
I'm trying to design a world in the Alcyone A system of the Pleiades. Alcyone A consists of three stars. The main star is 3.4-3.8 solar masses. There is a very low mass star < 15 million miles ...
I am envisioning a world around a red dwarf star. The planet has violent and accelerated (due to higher geological activity) plate tectonics and has a magnetic field about 75% the strength of the E...
Edit: Before I give up on this I wonder how could an advanced civilization create conditions on a small planetoid (Ceres sized?) to keep an Earth level breathable atmosphere? It seems like its impo...
My question is the following: How could I design and/or justify a habitable planet that is 80,000 km in circumference? The planet should: Be habitable Have a gravity similar to earth's Have act...
(See diagram) Presupposing that a Rocheworld can even exist... I imagine that sunlight would work more or less the same in the atmosphere of any part of an Earth like planet that was tidally lock...
(Please see diagrams) This is a question regarding an area of a Rocheworld scenario that I haven't found anything on. It is suggested that the OUT side of a planet that is tidally locked with an...
Imagine a world whose sun is swinging like a pendulum above a flat surface. This is a sketch of the diagram. A complete cycle lasts twenty-four (24) hours (from an end to the other and back aga...
So I have a planet with tectonic plates that are separated by massive canyons that reach all the way down to the mantle. Obviously this means that the planet is very unstable and violent, experienc...
Assume you have access to some very large amount of energy but there are no exceptions to currently known laws of physics (for example, you can't go faster than the speed of light). Is it possibl...
(Warning: do not try this at home-system) Preamble Hello humans, we need advice. Let's say we have just successfully defeated and killed a Horror From Beyond Reason who happened to be multiple t...
A good friend of mine, who's a doctor, is very well traveled, and he told me he's seen skies of different worlds take all the colors of the rainbow (and the grayscale to boot). I suspect that he mi...
I am attempting to create fictional, stable P-Type binary system, featuring a gas giant in a stable orbit, with a habitable Earth-like moon. "Is a Jupiter-sized planet plausible in a habitable zone...
There are a lot of solutions for living in low gravity environments. (e.g. centripetal acceleration, linear thrust, etc.) But what about living on high gravity planets? Is there anyway to build or...
How could I calculate the habitable bounds, in relation to temperature, near the twilight zone of Gliese 667 Cc? Assuming an Earth-like atmosphere and no tidal working. Here are the numbers that ...
Some research, and some answers from others, have suggested that a massive (planet sized?) sphere of gas in space, with no hard core, but breathable air inside some part of it, can create enough of...
I want to have an intelligent life-form on a planet, but I want this life form to be technologically limited because of the lack of discovery of fire. What changes would have to occur in the atmo...
Say you have a planet and the planet has a moon: could the moon have visible satellites as well? I don't mean a gas giant planet, I mean something habitable by humanoids or humans. Will the moon'...
I'm trying to build a world that is almost completely water, but I couldn't come up with an explanation for WHY the world was like this. The world has the same gravity and atmosphere of Earth. It a...
In the year 2588, ISRO (Indian Space Research Organization) along with collaboration of NASA had discovered a new planet named Accio several light years farther than Pluto. Scientists have computed...
Mars has an inactive mantle and core and thus little magnetosphere to speak of. Assume that a lunar mass object is placed in Mars orbit at 300,000 kilometers out (one light-second). Given the tidal...
I'm working on a quest (Space game, but don't ask, it won't be good in anything but story and even that may be a stretch. XD), and I'm looking to use our solar system, Jupiter and Saturn specifical...
Chthonian planets are gas giants that orbit their stars so closely, the intense heat from the star strips off the gas giant's atmosphere, leaving behind a tail of gas. This turns the gas giant into...
I've been trying to figure out a model (or find a relevant paper) for calculating the approximate day/night and periapsis/apoapsis temperature variation for an earth-like planet that has a high ecc...
So I have a planet that is slightly larger than Earth, orbits an orange star slightly closer than earth orbits the sun, has extreme weather patterns and volatile tectonics. It has bad storms, tempe...
I've got this planet that orbits it's star slightly closer than earth orbits the sun. For story reasons I need it to have small yet severe radiation storms and I was thinking that either a weak or ...
So I'm guessing you guys know about the speculation that life exists on Titan. To me, this is very interesting but many point out that it would probably only be microbes and unicellular life becaus...
Let's say for some odd reason, a planet (while in orbit of something) travels at all times inside of a nebula. What all would happen to the planet? Could it sustain life (if sunlight was substitute...
For your consideration, a star system inside a dark nebula with a potentially habitable planet. Being a dark nebula, we Earthers can't see light shining behind the nebula. Further and therefore: ...
I'd like to explore some details on a so-called water-ball planet (i.e. a planet in the habitable zone of a sun, covered by a 100 km deep ocean). I am particularly interested where life could devel...
