So in my story/world I have a region that is straight up destroyed...demonic magic is nasty stuff. So we have rings Ring 1 (1 is in the middle) This ring has a diameter of about 200 miles. At...
I've been reading here for a little while, but this is my first question. I am trying to come up with either a concrete set of numbers for a single answer for a binary planet system, or a simple fo...
Star A Mass: 1.2 x Sol Radius: 1.157 x Sol Luminosity: 2.074 x Sol Temperature: 6,444 K Star B Mass: 0.63 x Sol Radius 0.691 x Sol Luminosity: 0.158 x Sol Temperature: 4,378 K Semi-Major ...
A star system consisting of two stars forms, with one being more massive. As such, the larger star soon exhausts its fuel and ends up as a neutron star. The secondary star has a semi-major axis of ...
So at some point in the future, humans have small colonies on the Moon, on Mars and many space stations in orbit of all the planets in the solar system. Everything is going great until one day some...
I'm thinking of a planet with one side too hot, and one too cold due to always facing its star. With the planet having a small ring, a "twilight zone" which may be habitable, I was wondering if a m...
Here is a link to an online animation of stars' movements in a trinary system. Basically, the three stars are orbiting around a barycenter; one (yellow in the animation, mass = 1) closer to it a...
I have built a star that is loosely based on a real-world star. It has the following properties: Spectral class G Mass: 1.03 M$_\odot$ Radius: 1.02 r$_\odot$ Luminosity: 1.05 L$_\odot$ Surface te...
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...
I could have sworn that there was a question that covered this, but I suppose I'm misremembering. If anyone finds one, let me know. Back in the early days of the Solar System, things were pretty b...
Suppose that a god has created a universe with nothing in it, except for a single, solitary celestial body. For simplicity, I'll call it a planet, although it most probably technically won't be. Fo...
By extremely high gravity, I specifically mean around 28 Gs. I recently asked this question with regards to inhabiting the sun, and surviving in the sun's gravity seems like one of the major challe...
I am trying to design a world where one pole is very cold, and the other is very hot. I don't mean that there would be instant death in either, but it is colder than our South Pole on one end and w...
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...
In the mobile game "The Path To Luma", the main hero travels to very tiny planets. Let's not think about where is the sun and how we leap through such small planets. What I want to ask is, if there...
I'm talking about ionized gas not the plasma in our blood. I have been reading science articles about plasma and they keep hinting at the idea of plasma based life. Here is my first example and an...
Say we had a planet which was a gas giant. Is it possible that at the core of the planet where meteors, asteroids, and comet debris had collected that there could be a layer of atmosphere similar t...
What I am asking is not if there is an possibility of an island (Isle of Wight size because it is an island I am familiar with) size tortoise , I will find a way around that, I just want to know if...
I am working on a project (The Longest Day), and I'm sure some people here have the necessary knowledge to give me some more usefull info. OK, here it is: Lets say that Earth's spinning speed dim...
So let's say that I have a world with a moon, you know kind of like we do on Earth. But with life on the planet, is it possible to find life on the moon? In the artifexian video on habitable moons,...
My question is pretty simple, all the details about the planet are pictured below.
Some details about the planet and its moon plus the host star. Star: 0.85 Sol, 0.54% of the Sun's luminosity Planet: 0.04926 (M⊕) 4836 km, 0.34 G, Orbits the host star at 0.901 AU. The atmosph...
By Mars sized I mean with masses between 0.10 (M⊕) and 0.25 (M⊕), the planets need to have independent orbits around the star. We can assume the habitable zone stretches from 0.70 AU, to 1.5 A...
I was imaging a system which has a black hole, a star and Earth like planet. The star and planet orbits around the black hole, but the planet has same orbital period as the star, which is a "quasi ...
I was wondering what is the smallest a terrestrial planet can be and maintain plate tectonics and generate a magnetic field, atleast to Earth's current age?
Would it be possible for a terrestrial planet say atleast >0.3 Earth masses orbiting in the L3/L4/L5 and L1/L2 Lagrangian points of a Jupiter sized planet in the habitable zone of a Sun-like sta...
The gas giant has a mass of about 2.13 Jupiter masses in the habitable zone of a Sun like star 0.981 Sol masses, all the moons will need at least >0.12 percent of Earth's mass and a Mars like de...
These moons orbit a Jovian planet with 0.52 Jovian mass and at 1.02 AU from a star with 0.98 Sol mass. 3.85 Days, 0.351 Earth, 0.68 G 15.4 Days, 0.242 Earth, 0.59 G 30.8 Days, 0.118 Earth, 0.44 ...
Since the Sun is the only star we know to have life in its planetary system, I came to wonder about if it was replaced by, say, VY Canis Majoris How far would we have to be so that we would still b...
For most of us, meteors are by far the ultimate planet killers. All it takes is one direct hit to suddenly wipe all life from the face of a world. But, rather than taking life away from a planet, w...
What is the minimum size of a planet that could harbor human life? You get to decide what the atmosphere is, but I'm reasonably sure that O2, CO2, and H2O are necessary components of the atmosphere...
Suppose we have a rocky planet (somewhere between Earth- and Super-Earth- sized) orbiting a star far enough away that it would be around Pluto's temperature if sunlight was the only heat source. If...
Lets say there's a super earth orbiting the sun at 3.00 AU, how thick would its atmosphere have to be to trap enough heat to make the planet warm enough for liquid water to flow on its surface?
I've heard a lot of people say that having two tidally locked planets close together would have adverse affects on both planets. I have two tidally locked planets at a distance of 16,550 miles apar...
Is there any way to make a planet with a corkscrew orbit (like this) that could host a sci-fi civilisation? It'd be amazing if there was a way to make life arise naturally, but colonize-able works...
Say you were to drop a (bunch of) human(s) at some past era of our Earth. I'm assuming they might encounter a few problems such as the composition of the air not being breathable, the water being t...
Let's say that in my planetary system there is a gas giant around the size and distance from the Sun as Jupiter. I need the planet to be similar enough to earth to be able to be inhabited natural b...
I'm currently heavily revising a story which is largely set on a habitable but not exactly hospitable moon of a gas giant orbiting on the outer edge (or just beyond) of the habitable zone around a ...
How do you go about boosting an already-habitable planet's habitability? I want to maximize biomass, hopefully cover the whole planet surface in luxuriant jungles and forests, brimming with insects...
All the worlds I've seen built by me or others have surfaces that are mainly water. Is it possible for a habitable world to exist if the world is mainly land? I'm only talking about 55-65 percent l...
I'm picturing a world with a permanent, dark, overcast sky, but I'm wondering how dark it can be before photosynthesis is no longer an option. It looks like there are a good number of plants that ...
Following this question, I had additional question of habitability. Assuming that life could exist on planet formed roughly twelve billion years ago, allowing complex life to exist as of seven bill...
Is it possible for complex life to exist on a planet with no tilt and no moons, and be so close to its sun that the equator would be far too hot to cross on foot and still survive, and its poles fa...
Consider a scenario where there is an over-populated solar system (not necessarily our solar system). Several other rocky planets and moons in this solar system are inhabited by the same humanoid r...
