Alright, so the primary inspiration for this is 55 Cancri e, the speculated carbon "diamond world" and to a degree, Nkllon, a planet in Star Wars that is essentially what Cancri is, but "confirmed"...
As the title say, can a planet have a different gravitational pull depending on its location in orbit around its sun? Is this explainable without magic?
Given a system similar to the Earth/Moon/Sun system, how would one go about making solar eclipses rarer than they are here on earth, but keep new moons similar to how they currently are (or at leas...
In my galaxy, I need a planet that is far enough away from its star to be relatively cold compared to Earth, but not so cold that liquid water cold not exist. The planet has 2 continents, 1 northe...
In this universe humans have advanced far enough to be able to colonize planets in our system but not enough to do interstellar travel. Earth is united and they have moved beyond countries and bord...
Medrunner Lao Dorn and his team have been given a mission. A young woman has contracted some sort of parasite that is slowly eating away at her vital organs. The doctors on Oberon are unable to do ...
A Traveler from a very advanced civilization has visited the Solar system. He found the humans likable, and decided to leave them a boon. For some reason, he couldn't do anything directly to the Ea...
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...
I have a planetary system that consists of two close stars: A Sun-like star - small but bright A much larger, but much darker star (about 5-10 times larger) A habitable planet orbiting both of th...
I am writing a novel about what it will be like on earth 500 or so years before the death of our Sun. The Sun is heating up gradually and one day that will negatively affect life on Earth. I know t...
I once show a picture depicticting the idea of an ultimate solar system: Image Copyright Sean Raymond In this solar system there are 8 planetary orbits, each containing 52 equal-mass, evenly-spa...
The Emperor (may he live forever) plans to visit the Solar System on a rare royal visit in ten years' time. The Bureau for Interplanetary Tidying have decided that the Asteroid Belt is an eyesore t...
I'm writing a story that will eventually escalate from being focused on one planet to the entire star system that planet belongs to, and finally to a big story involving the two nearest star system...
Simple question that might seem odd. Not going to get too specific but I am curious, more or less, as to what it would look like for a planet that had a moon (A habital one) which was in essence ti...
Is it possible for a planet in our part of the galaxy to have a night without stars? I'm looking for some kind of natural phenomena that would hide the stars, but allow the sun to rise and fall as...
With the Kuiper Belt being composed of well over 100 million objects - some grand, some insignificant - is it possible to hide an asteroid base from enemy sensors within its confines, combined with...
I would like to know how close two planetary systems could be without having an adverse effect on each other. My goal is to drastically improve the chances of having habitable planets near enough t...
This question has been rewritten to incorporate all clarifications. On Earth, half the planet is illuminated at any time (let's ignore eclipses). Axial tilt lets day lengths vary, but over the cou...
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...
I was in the shower the other day thinking about the sun going Nova, you know...like you do, and a thought occurred to me: Could you turn the sun into a stable, mostly closed system? Some detai...
There are many questions on WBSE that cover most aspects of building a planetary system. (some examples below): Creating a realistic world(s) map - planetary systems How many planets should I ha...
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 ...
Now that FTL travel is here there are all sorts of family outings we can go on. One of these is a scale model solar system lovingly made by hobbyist Barty Slartfast. In full scale Sedna is thre...
In my previous question, I asked how much mass the Sun would have to lose in order for Saturn's orbital velocity to be its escape velocity. The answer proved to be somewhat unexpected - when the S...
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...
In my book series (link here), there is a star system at the northern edge of the galaxy called the Ryu system. I am planning for this star system to be huge, encompassing 120 planets. The vast m...
In the book 2010: Odyssey Two by Arthur C. Clarke, Jupiter is turned into a star. Presumably this is done by making it more dense, so if Jupiter were to reach that density and become a star, what w...
I'm aware that 'tatooine' worlds don't make good habits for planets, normally. From what I've read, either a planet has to orbit one star really closely, or orbit both stars from a really long dist...
Segue 2 is a galaxy with only about 1000 stars and is 111 light years in radius. It has a light output only 900 times that of our sun. (This is a real galaxy in our universe) However, I want my fi...
Let me clarify on the title, because this is important. In recent years, people have been feeling less comfortable calling the only natural satellite orbiting Earth a moon. It may not be the larg...
Other posts from this thread will be posted here: How to make an Earth with 27 suns work (Closed as a duplicate of the follow up, Attempt Two) How To Make an Earth with 27 Suns Work, Attempt Two...
So the background is simple: in the modern day a CME (coronal mass ejection, a solar flare that has escaped the sun) hits the Earth and destroyed all the electrical equipment causing planes to cras...
Imagine two identical planets planet A and planet B, orbiting the same star. Is it possible that these two planets follow the exact same "route" as they orbit their sun, but are just distant enoug...
I am drafting a short story about a small object orbiting the Sun at the precise 'speed' as Earth's opposite the Sun, undiscovered by us due to its position. The problems I see with this include t...
Piggybacking on this question: Could soft matter infused with nano or pico sized magnets be used to clump together so that we could create environments with it? ...So we have a planet that has low...
I am building a planetary system, but I always thought how many planets should I have in this system. When you look at our solar system there are 8 planets. Other exoplanetary systems can have up...
Back home, Venus is a twin planet with serious issues. The average surface temperature is 900 degrees Fahrenheit, atmospheric pressure is 92 times greater than ours and carbon dioxide makes up 96%...
Let's suppose a solar system: A main-sequence star similar to the Sun. G2V or so. A Hot/Warm Jupiter HJ with a semi-major axis somewhere from 0.5 AU to 0.0001 AU. An Earth-like planet EL with a s...
I am creating a world in which a civilization has achieved advanced spaceflight and has begone colonizing other planets in their solar system that is similar to ours, but with more planets. However...
It's the height of humanity's space-colonization golden age when casual interplanetary travel has become possible and humans have either colonized or established large space stations around nearly ...
One of the answers to What could make a star green? describes a living Dyson sphere made of photosynthetic, plant-like material. What type of star or star system is ideal for a plant-like Dyson sp...
In our story's universe, a solar system is hand-crafted by a deity with seven smallish bodies working in a way that I can only describe as Lagrangian Points, where all planets have the same orbital...
Part of a series I'm starting since the recent What could make a star green? did quite well and others could use the information here in their worlds. There aren't any "violet" stars. When a ...
I've been trying to create a water planet with certain aspects. I wanted it to have a breathable atmosphere and to be a microgravity environment. I'm developing humanoid characters that can breathe...
I have a binary star system and have come up with some stats for it. My primary star is an F-type, with a mass of 1.3 sols and a luminosity of 2.197 sols. My secondary star is a K-type, with a mas...
Basis We are in the universe we call our own, on the planet we call Earth, in the physics-set and known reality we assume. There is no flat-out "magic" or other things along those lines, so far a...
Let's take a world that is based heavily on Elon Musk's specific ideas of Mars colonization, to whit: Launch technology from Earth evolves to be to <$100/lb cost to launch ratio, due to reusab...
BACKGROUND The world I'm designing currently has a gas giant of the type known as a hot Jupiter orbiting close to the sun and causing solar flares. I would like the inhabitants of my Earth-like wo...
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 ...
