I'm trying to figure out how quickly a planet could rotate while also having a single air flow cell, such as Hadley cells, that would circle from hot pole to cold pole, etc. as in the case of Tidal...
Rogue planets are generally not to healthy for us humans to live on. No permanent source of heat or light means that generally they are a pretty cold place. Plenty of other problems arise too, but ...
Assuming the planet is earth-like, with more surface water and atmospheric oxygen, and within the habitable zone of a sun-like star, how can a moon orbiting this planet retain a thick atmosphere? ...
Is there a habitability zone between the primary and secondary stars in a binary star system for a planet orbiting only the primary star at a distance less than that of the secondary star and, if s...
A universe-destroying parasite is set loose, and basically earth is placed under magical quarantine. (Think of it like the world is wrapped in magical cellophane.) My question is, how would earth's...
This question is pretty straightforward: What is the minimum and maximum distance for a planet to be in the habitable zone of an average sized (not biggest, not smallest) Red Dwarf star?
I'm trying to create my planet orbiting a red dwarf, honestly I've thought other scenarios but it's like every answer opens new questions. I'll just say what I want my planet to be and I'd like you...
Is it possible for there to be a "solar system" of sorts with a black hole and a few suns orbiting around it? Could that system be stable and (if so) would it be possible for some civilization(s) ...
My question is in the context of a fictional super-Neptune that lies in the habitable zone of its host star system. Giant planets only form beyond the Frost Line of their protoplanetary disk, and...
Essentially, I'm designing a solar system for form of alien life. For the sake of ease, the star is roughly similar to the Sun, and the habitable planet follows an orbit anywhere between Earth and ...
The Arctic ice cap is melting away soon. Some (probably misguided) ecoactivists think it would be a good idea to safeguard certain indigenous species of the North Polar region (especially mammals) ...
Larry Niven wrote a novel called The Integral Trees, which was followed by a sequel The Smoke Ring. This is Wikipedia's synopsis of the setting: The story occurs around the fictional neutron st...
So, vaguely, I remember from earth science that when submarine volcanoes erupt they eventually form archipelagos. My question actually has several parts; Starting with the first eruption to bre...
I have developed a fictional planet with the following atmospheric composition; 60.4% Nitrogen 27.6% Oxygen 9.8% Xenon 1.5% Water Vapor 0.64% Argon 0.06% Carbon Dioxide Is this breathable to hu...
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...
The scenario is based on the fact that a tight binary of two neutron stars does not hold for long: The two bodies lose energy in the form of gravitational waves and they spiral towards each other a...
I'm trying to construct a solar system, and I'm toying with the idea that the planet capable of sustaining life was initially outside of the habitable zone, but the star's advanced age has caused t...
To my understanding, part of the reason life is able to exist on Earth besides its ozone layer is due to its magnetic field, which protects the planet and its life against solar winds and keeps the...
Epimetheus is a planet with about three times the mass of Earth orbiting a sun-like star in the Andromeda galaxy. However, two major factors separate Epimetheus from Earth. First, it has a thick at...
In the Halo series there's a habitable planet called Harvest with a diameter of 4,012 kilometres, and gravity 99% of Earth's, though the planet only has 9% of Earth's mass. If such a planet is poss...
My world is a 1AU radius, 12000km thick Dyson Sphere with 6 equally spaced holes, 4 filled with water. The two main problems I have are gravity and heat. This question concerns heat and how to stop...
This question is kind of hard to explain succinctly, and I apologize for that. Obviously, humans experience acute effects from UV light on Earth in a matter of minutes near the equator (UV index o...
For a complex world-building scenario I want a habitable moon orbiting a habitable earth-like planet. The habitable moon should allow for flora, fauna and landscape as similar to earth as possible....
Imagine a world full of islands. No continents, just average-sized islands. There are so many islands, that it would look a bit like this from space: Now, imagine that the sea is very, very deep...
How difficult would it be for a human to survive on a planet with an atmosphere 2-5 times as thick as Earth's but with gravity like Venus? Would such an atmosphere be survivable? If yes, then how ...
Suppose there's a planet in the habitable zone of a class F star, a bit smaller than Earth and about the same density, with 80% of earth's gravity. How far away from the planet would a brown dwarf ...
To clarify, I realised that I kind of ran into a problem trying to check the orbital stability of two fictional planets in orbit around the real life 61 Cygni binary star star system. To explain...
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...
My idea has been a colonized planet or moon with incredibly strong winds so that life is only possible in deep valleys protected from the wind. I recognize that wind is primarily driven by tempera...
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 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...
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...
I'm thinking a planet orbiting a nearby star colonized by human settlers sometime in the not near, but not too distant future. How small could a planet be while still standing in as a relatively c...
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...
I'm working on a story right now where darkness plays an important role, and I had the idea to set my story on a rogue planet, a planet in perpetual darkness because it has no sun. However, from wh...
I created a fantasy map a while back, but only recently have I realised it may have a major problem. There is next to no land at the equator although some land between 0-30 degrees. The vast majori...
I'm seeking a hard science setting for a piece of xenofiction with a decidedly non-sciencey feel. That said, there is no magic or magic technology. The idea is as follows: A red dwarf star has a...
Well, the strongest barrier that might prevent life from appearing might be described by that analogy : it's like hoping to cook an apple pie by mixing the ingredients with random quantities and a...
My titled question was, can a planet without one or more moons be habitable? In more depth, how would that planet be affected overall, without the moon to affect the tides and without providing li...
This one source is stating a desert planet the size of Earth could maintain habitability at 0.38 AU from a sun-like star, but I highly doubt this is possible. What are some factors that could make ...
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 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...
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...
I'm trying to build as close to a 1:1 Earth as possible, but finding information on a non-jovian moon-based planet is extremely hard to find. I tend to ramble trying to explain things in a non-list...
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 ...
