I'm creating a short story about two planets, roughly the same mass, orbiting around each other somewhat like the Earth and the Moon. Would it be possible for both to also be rotating at the same t...
For a gas giant to have a habitable Earth-like moon, in a P-type circumbinary orbit with the stellar classes of the 2 stars being A7 type III and F2 type IV separated by a distance of 2AU to 3AU, w...
I am building a habitable Earth like planet, but instead of it being in a solar system it is inside a Nebula. The actual composition of the Nebula is uncertain at this point. I am thinking the pl...
Scientists seem to be vacillating as to whether a Red Dwarf planet could support life or not. Imagine a G-Type star much like our Sun. Imagine an orbit that would make an Earth-Sized planet warmer ...
If I were to attempt the colonization of a planet with preexisting life, how would I manage to pinpoint a candidate planet from the comforts of Earth's orbit? I am interested in the stars somewhere...
So I'm thinking about writing a fantasy and I want certain parts to be plausible (though I'm sticking way towards the end of soft sci-fi). In the world I'm creating there is a cataclysmic tide tha...
I'd like to set a story in our solar system with Earth and the inner planets becoming uninhabitable and a new planet being required. If human beings decided to build a world by making slight deviat...
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...
Is it possible for a planet's surface to be wetlands, such that… There are no great land masses (continents). There would still be two polar caps, and I am considering a greater width of equator ...
Is it possible for a sun-like star to hold on to about 16 planets? If so, where could the habitable zone be located at?
Ok, I know it sounds very far-fetched, but I'm curious. We know that Binary stars truly exist, and that binary planets are all but confirmed. Here's my insane question: can there be a TERNARY pla...
Imagine a desertic planet, large dune seas and barren rocky wastes ... Mountains and the like suggesting a past geological activity and even water once exhisted on the surface. Now though the pla...
Let's suppose we live in different star system with two similar-sized planets (with a mass of three and a half Earths.) We live in Planet A, which is habitable. For some reason, Planet 2, our neigh...
You've most likely heard that planets can exist in the shape of a donut, also known as a torus. These toroidal worlds could even support human life, as long as it spun fast enough to balance out it...
Say in an alternate timeline, Earth developed with more moons. Many, many many more moons. In fact, it developed with the absolute maximum amount of moons a planet of its size and mass can physical...
Can a planet (gas giant or otherwise) have rings not around the equator, but instead rings running from pole to pole? Think of Uranus' rings, except the planet isn't on it's side
In my story, I have a fairly advanced human race who is at the point they want to start terraforming planets. Of course, all of the materials necessary have to come from somewhere, and the proposed...
Some research papers, such as Arnold 2005, has investigated the possibility of using artificial megastructures transit signatures as long-range, long-lived and low-maintenance signals of unambiguou...
Suppose a highly tectonically active planet, slightly smaller than Earth, has attracted the human race's attention due to its mineral wealth. Its landscape primarily consists of mountain chains, vo...
Is it possible to have a planet where the atmosphere is mostly water vapor instead of mostly N + O2 with solid ground, so not a gas giant? In the sense - how close to the center star(s) should it ...
I am working on a story where ships are tricked and crash land on a volcanic planet due to some sort of electromagnetic interference. The survivors of the landing essentially become gladiators on ...
If all the fresh water were at least 25% deuterium, would humans be able to survive? Would there be significant other detrimental side effects to human physiology as a result?
I'm imagining that a group of humans was transported to a different planet almost 100 thousand years ago. The planet is similar enough to Earth that they can survive, and already had other earth-...
Assuming a civilization has the technology and capability to build a worldship, a planet that doubles as a spacecraft, installs an FTL drive on it and has the energy to power it, what would the eff...
Has anybody made any serious calculations of what the climates on Earth would be if our planet had a larger axial tilt? The most interesting are the cases of 45 and 90 degrees.
The rotational axis of the Earth is slightly tilted now, but I would like to tilt it to 90° - something like Uranus has - and make the Earth rotate with one pole always facing one direction - eg. ...
I am hoping to create a planet with a greater rotational speed, making it oblong, thus causing differential gravitaion from the equator to the poles. I am hoping for the gravitarion to be lighter t...
For my science fantasy story, I need a particular setting for my world. I need a planet (Earth or earth-like), habitable and with complex life forms like our planet. However, over time, this planet...
Recently, a planet around Proxima Centauri has been found. It is in the habitable zone, in the sense that if the planet was a black body, it would have a surface temperature of −39° Celsius. The p...
This might be a little difficult to explain, but basically: the concept of "atmospheric ocean" is a gas that is found pretty much everywhere on the planet. Probably very dense and sinks to the surf...
The world I am envisioning is a rocky planet with oceans, plate tectonics, atmosphere, and several other similarities to our globe. The mass and size is roughly equal, but its moon is orbiting much...
I'm brainstorming for a rocky planet with similar mass to that of Earth's, orbiting a red dwarf star. It is tidally locked with no natural satellites, yet I'm bent on having liquid water on both su...
I was wondering would a planetary drill be possible? The drill should go inside the planet on one side and exit on the other. Would that kind of a drill be possible on Earth and if not on what kind...
Is it possible for a planet to have very little visible-light energy and receive enough energy to support life from ionising radiation? Dim light, including starlight and ionized-air glow is accept...
The concept of a metal poor world is one that I find deeply fascinating. In part because I fell in love with the setting that first exposed me to the concept, Dark Sun. So I want incorporate a ver...
Fo my question, I'd like the moon to orbit around a saturn-like planet without rings. This moon would be located at a million kilometers away the host planet. the moon's size would be about 12 000...
Brown and white dwarf stars are thought to have habitable zones but are very close orbits. Plus these planets will experience strong tidal forces and be tidally locked. But if you have a large Ea...
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...
Epic fantasies typically depict northern areas as cold and southern areas as relatively warm. Is this just to play into reader expectations since that's the way it is on Earth, or is there a scient...
I'm trying to construct a habitable world which has a sun orbiting around it. I know a star can't orbit around a planet, because a star is much more massive than a single planet, which has been kno...
If we were gonna develop a colony on mars would it be possible to explore geothermal energy and would it be viable? (Assuming we could transport the required equipment) Edit: Recently I found thi...
The vast majority of the sun's energy is wasted -- the light and warmth are sent out in a spherical shape, and the planets only pick up those little bits of energy that happen to be going in the ri...
The question: What characteristics are necessary for a planet to be habitable for humans? What should the generic star and planet be like? The life forms are human, so they Need to have access ...

So there's a planet that is used as a farming world (food) for its system. This planet has a single, Mediterranean sea-sized ocean on it and lacks any other major surface oceans (he hasn't excluded...
In the Chronicles of the Riddick there was planet Crematoria. Temperature during the day there was 372°C and during night −182°C. There is not much information about about this planet avaiable. ...
I have a world with a moon, much like Earth and the Moon, except that the planet is almost tidally locked to the moon. The moon therefore appears to move only very slowly through the sky, and take...
Working on a bit of a story that includes the ejection of the planet Jupiter from the solar system rather suddenly with all of the planets staying generally within it. I understand this is complica...
What artificial disaster could disrupt the orbit of our planet? Not necessarily making it leave the Solar System, but maybe changing its trajectory around the sun. And by artificial, I mean that th...
Going off of my other question here, I guessed that a cube planet could work out. BUT, would it be possible for the planet to exist and function as a (relatively) normal planet with life on it with...
