So we have a Super Earth of ten Earth masses, just on the threshold, and it has three Mars sized moons (so a mass ratio of 100/3, more than Saturn Vs 3 Earths). They go 40,000km, 100,000km, 250,000...
What size and/or mass of impactor would need to impact the moon to destroy its tidal lock so that it's orbit is noticeable within its phases? What side effects would this impactor cause, and how wo...
Would anyone be able to check some math/ let me know if I'm thinking of this the correct way? I had an idea of the moon appearing basically stationary in the sky, but in fact it orbits just faster ...
So I want my planet to have six suns, but I'm not sure how far apart these stars would have to be from each other to not produce adverse effects on the planet that would prevent life from developin...
How many moons would be required to induce almost continual tidal pull to create a near constant tidal riptides?
I've begun the laborious (but fun!) process of putting another world together. Known constraints include: Habitable, (super-)Earth-sized, tidally-locked moon to a gas giant; the giant, where vis...
Bonus: How much would the increase in lunar mass increase average tides? & which factors would cause the Earth to become uninhabitable?
The setting: A planet with two main landmasses, each one's center located more or less at each pole of the planet. Liquid water ocean in between them, wrapping fully, if not directly (due to the ...
I'm thinking of having a world that has a moon that's been partially split (so not fully halved) with the debris slowly separating from it. At night you'd see the split moon mainly and lots of var...
I have a moon covered in liquid water that orbits a super-Earth very closely. As you might imagine, the tides are incredibly strong on this moon. However, it is tidally locked and so does not exper...
I would like to have an Earth-like planet (~Earth gravity, ~Earth day, ~Earth year, and liquid water oceans) with extreme variance in its tides. I want the lowest tide to reveal about 30 miles of f...
In my answer to another question, I suggested that the Super-Earth in question be tidally locked to its host star for a period of time while part of its surface experienced a bombardment. After tha...
I'm creating a new setting for a novel. I'd like to build a world where the interaction between the planet and its satellite/satellites can generate a normal tide excursion around 6/8 metres. Furth...
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...
I've seen many questions about tides and tidal variations on a wide variety of interesting single star, multi star, single planet, binary planet, single moon, multiple moon, and even ring system co...
I have a planetary system in which there is a huge planet and a moon orbiting it which has an atmosphere and water (and actually everything needed to sustain life). Thing is that I'm sure the mass...
I'm trying to create a people that live on this rolling tide (see previous question or on 'millers planet') but I haven't figured out where they would get wood to build their boats/homes. If the ti...
Assuming a situation similar to this, where the moon causes slower but massive tides that slowly encircle the globe. Would the poles be constantly underwater or not underwater (like A or B below)?:...
I'm working on a story where the characters are stranded on a planet that turns so incredibly slow that it acts like a tidally locked planet, with one side burning and the other frozen. However bec...
I would like a earth-moon system like Pluto-Charon (but with earth instead of Pluto) where both will be tidally locked to each other within something like 3 billion years (before complex life appea...
I'm writing a short story that takes place on an imaginary planet that is 88% ocean. The planet has two moons and one continent that is regularly flooded under 500 to 1500 feet of water. The tides ...
I'm building a world that orbits close in to an M-Dwarf sun. I've figured out a bunch of the physical parameters of the world, I just can't quite get a solid handle on my tides. I know my tides wi...
I'm building a very small homeworld (0.602 M$_e$) with a very large moon (0.0711 M$_e$) that orbit each other at a barycenter about 7.12 planetary radii (1 R = 0.870 R$_e$) from the primary's cente...
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 actually trying to create an alien ecosystem, so changing orbits, what's exhibiting tidal forces and the geography and such is welcome if needed. I also wonder how stable a setup with dramatic ...
This concerns a habitable, earthlike moon orbiting a gas giant, which is not tidal locked, and has an elliptical orbit eccentric enough to avoid frequent deep winter freezes (the freezes do happen,...
How would waves and tides work on a planet that is completely covered by Ocean? It would have: Oceans of Similar depth to Earth's Atmosphere extremely similar to Earth's Same type of star and di...
I'm building a world which is 50% covered by the sea. For approximately half the year, the sea covers one hemisphere; for the other half it moves to the other hemisphere, leaving the first a dry se...
I saw this video a while ago, and recently it's gotten me thinking. Towards the end of Artifexian's video on gas giants and habitable moons, he mentions the idea of having 2 habitable moons in a ho...
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...
I'm building a fantasy world with a planetary core that gains and loses mass in a predictable manner. I want the gravity to increase and decrease by 50% in both directions over a period lasting 2-3...
If the Earth had Saturn-like rings going around the equator would there still be a need for a moon? Would the rings be able to take care of the tides because of their gravity? Would the moon become...
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 (...
I am making a world to be the setting of my future fantasy works, which is to say I really have no story planned but I want to have a world for it when I do and I want said world to be likely give ...
So given an inconceivably Earth-like planet with two moons in slightly differing orbits, how would the changed tidal system affect the wildlife? Specifically, What general type of marine wildlif...
I am looking for help on the following: Will that have any affect on the length of days and nights? Would having two moons create a higher body of water on the planet due to increased tides? (i....
Take the earth-moon system. Shift the moon's orbital plane about 90 degrees so that it is passes over both poles. What would the tides on this world look like? Sub-questions: What would the cy...
Say the moon is drifting further away from Earth at an astonishing rate of 3.14159km each year due to the crazy tides, the rising sea level and shielding us from stray asteroids. Given 150 years ti...
I designed my Kepler Bb planet to have 4 major moons. They each have a differing trajectory and are in resonant orbits for stabilization. I also designed the planet to have earth gravity but be big...
I'm creating a fictional planet that orbits a gas giant (a lot like Jupiter). I'm working out all the issues listed here and here. But what I'm really having trouble with is the size of the tide. ...
A large group of people has been banished from Earth and punished to scrape out a perilous existence on a strange planet. The planet has breathable atmosphere, and consists of an immense ocean teem...
