For this question, assume that the planet is Earth-like in almost every way, and is in a system like ours...the distance from the sun, orbital period, rotation, axial tilt, etc is all pretty much t...
I will be writing a short story about humans landing on an earth-like forest planet with a gravitational force of about 3 meters per second squared (In contrast, Earth has a gravitational accelerat...
The enormous shield volcano that this question was based on was held up by magic or God. It presented some very interesting conditions for alternate worlds so I thought I would develop that train o...
How can I arrange for a planet to have a much greater temperature range between the poles and the equator without it being tidally locked? Edit: By "much greater" I mean the temperature at the pol...
I have an Earth-sized planet in a Milky Way-like galaxy with all the land located at the equator, in a 2000-km line around the planet. There are small islands near the landmass, but no land anywher...
I just asked myself what is the role of the mountains on Earth? Well there's a well known role for the climate and weather. But is there a kind of physical or geological role? What would happen i...
What planetary parameters such as plate tectonics and volcanism etc would best encourage the most uneven planetary surface on an earth like planet? I want a world to be covered in very uneven terr...
Saturnian moons Iapetus, Atlas, and Pan all have equatorial ridges. There's a few explanations as to why, but the theory behind why Iapetus has one is what intrigues me. (https://en.m.wikipedia.org...
I created this climate map based on the Koppen Climate Classification map. In this scenario Australia is moved 10 degrees of latitude further south and the Lake Eyre basin is filled (shown in map...
I am looking at realistic options that could damage the Earth so severely that it would be impossible for mankind to survive there and that would also not allow us to just colonize other planets or...
Would it be possible for a spaceship of some sort to descend from space and through the atmosphere of an Earth-like planet, not land, then turn around and head back into space? In other words, coul...
Imagine a very long bridge (Visbi Bridge - named after the designer) across an immense canyon - really almost a wide deep gorge -use on an earth-like world. My concept is that part of the support o...
Start with a planet just like Earth as of today (whatever today means when you are reading this). For simplicity's sake, disregard mankind's continuous spewing of greenhouse gases into the atmosphe...
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...
My character kills a goat in the mountains and eats some of it for dinner. What kind of plant or mineral could he use to preserve the meat to carry with him so that it stays fresh and doesn't becom...
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.
It's my first time writing an original story and I have this idea, but I don't know if it could be scientifically feasible. My story would be medieval fantasy with magic, but I wanted to add a twis...
The consensus (1, 2) is that the reason most continents have relatively few large animals compared to Africa is that humans, even stone age humans, were able to drive them to extinction. African a...
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 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...
In my latest draft, a worm-like species buries itself deep below the crust of their world and consumes/gathers tiny amounts of heavy metals. Can you think of any plausible reason why a wormlike cr...
I'm building a mining colony world with large mine-able deposits of rare earth elements (REEs). One source of REEs on Earth is alkaline carbonitite magma. On Earth, I believe, it is thought to be d...
For story purpose I am trying to design a mass transit system for a perfect city. Right ... maybe not so perfect, if you look carefully into the details, but actually the mass transit system is sup...
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...
A couple friends and I have started a world called Lothaucan. On this world there is a continent called Novara with a circle of islands as its key feature. (seen in the mid-left of the image) I...
This is specifically about the climate, and where on the planet it would be mildest. Imagine Earth, rotating at the usual distance from the sun. Except, it is tidally locked to the sun; a so-calle...
How could an earth sized and broadly / liberally earth-like planet have plate tectonics but still experience zero or weak / little earthquakes? How can I have the weakest earthquakes possible while...
I'm curious as to what the implications to any navigation system are: ship trekking aviation etc. Will their compass change shape (as being spherical), or might they dump the compass alltogeth...
2017, flying islands just appeared in the sky. Different places in the world, different sizes. The biggest one is about the size of the Corsica french island. They have similar ecosystem than Eart...
I'm designing a world, and I want it to have major geological changes over a short period of time. This includes continental drift, which I'm assuming should have some interesting results. In parti...
Since I'm creating a "new world" for my story, I wanted to know if the following conditions would work for an Earth-like planet: Its moon (more or less same size as our moon) being much closer (...
Tech level: more or less comparable to contemporary. Location: forsaken, habitable planet with population of approximately 10-20 milion. Wealth level: first world equivalent Covering capital, ma...
On a tidally locked Earth-like planet a big part of long distance air routes would have to approach the hurricane eye and some may even benefit from it. On Earth aircraft are able to save time and...
An illness has been slowly spreading throughout the inhabitants of my agrarian society, decimating villages. The first sign of infection is the excessive production of slimy yellow saliva, and sinc...
So we have had multiple questions on having multiple moons and this is another. I did check and didn't find questions that covered this specific setup. I have an earth-like world I am working on, ...
I was wondering what would happen to life, when an infamous epidemic plague would be able to infect and kill any imaginable plant, be it on land or in the waters. Would the lack of oxygen eventual...
I have two earth clones, in essence, separated by *16550 miles (26350 kilometers). They are, of course, tidally locked, and orbit each other once every 24 hours. These planets orbit a sun identical...
Here is the situation. A planet fairly similar to Earth is orbiting binary stars, one O or B type and one F type. Sometimes the stars are close together in the sky, sometimes far apart, sometimes o...
For story reasons I need a situation with a planet around red dwarf, which already has had the equivalent of a Great Oxygenation Event. Simultaneously I also like the planet to be mostly without ac...
If I want an Earth-like planet, what kind of star can I use to achieve that ? According to the Harvard stellar classification, our Sun is a G-class star. The best would be to have: Temperature ...
I'm writing a species of dragon-sized butterflies¹ as flying mounts into a low-magic fantasy setting², and would like to know if these creatures have to be imbued with magic, or if they could jus...
This is a followup to this question about city building on flood plains. There is a civilization that developed along the rich varzea flooded forests of an enormous rainforest river, larger than ...
My colonists have been terraforming a planet for centuries. They chose this exo-planet for its many earth-like qualities (size, gravity, Goldilocks zone, volcanos, similar sun). However, it is like...
Someone made the Earth. They placed man on the surface and gave them plants, animals, the waters, and the mountains to make their life compete. The Earth exists within a spherical firmament upon ...
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...
From this chart it appears that the star types closest to our own are K-type (oranger, a little cooler, and less than half as bright) and F-type (bluer, a little warmer, and much brighter). If I w...
So I'm wondering if it would be possible for humans to live healthily on a largely Earth-like planet that was covered almost entirely in salt water. Landmasses would all be islands, with only a few...
I've created a small planet, about 90% the size of Earth, which orbits a pair of twin dwarf stars and is Earth-like in many respects. This planet's atmosphere is highly electrified, with lightning ...
I have scoured through the archives here and cant exactly find what I am looking for in terms of a specific setting I am trying to render in my novel. Let's say the world has built up so much smog...
First off, let's get definitions out of the way: A "race" here is defined as stable, heritable, phenotypic, clearly visual distinction between large demographic groups living in different geograph...
