My question is simple: How many nested moons are physically possible? If our moon had a moon, that would be a nesting of 1. I'm assuming it's easily possible for a really big moon to be orbiting ...
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...
Related Question : Can we 'beam' energy from the moon? I was wondering if instead of 'beam'ing energy from the moon, could it be possible to extend a power cable from the earth to the moon? If th...
I have a habitable moon orbiting a gas giant, and there is another moon orbiting the planet on a closer orbit. The cultures on the near-side of the further, habitable moon use the transit of the cl...
I have a "simple" question that is the basis for an idea I'm developing: Is it possible to terraform the moon and, if so, what type of technology would be needed? I understand that this isn't th...
I have a world idea (and definitely not the only one with such an idea in which the main location is a moon of a gas giant, that has life like on Earth. What are the effects of the presence of the...
In my story, Earth follows an alternate history where this civilization has reached the same level of development as us, today. Assuming that this civilization can lift a second moon half the size ...
Imagine: A Kardashev Type I civilization mainly resides on a planet analogous to Earth, with one moon, analogous to Earth's moon. Eventually, the society grows so complex that machines filling spac...
My setting is a habitable moon with freestanding water orbiting a gas giant. Originally I thought the gravity of the jovian world would tend to draw water toward the tidal bulge of the moon itsel...
This is an answer I found while looking up random factoids. And it's gotten me wondering. ((If I should take down the picture, and just paraphrase the text, please let me know.)) Charlie here i...
A mad scientist decides to hold the moon hostage for one million dollars. He accomplishes this using a tractor beam of arbitrary power to trap the moon directly between the Earth and the Sun. The t...
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,...
Ok, this is take two. Hopefully this is specific enough. I have a link to the original question here. And for those of you eager to see my sources for this, I'll link two videos here from the You...
Considering our topic challenge, and the fantastic eclipse last Sunday a question came to me. Could there be a stable (relatively speaking) planetary system where a(n) eclipse/alignment would actu...
I have a habitable moon orbiting a gas giant. The moon is not tidally locked with the gas giant. The orbital plane of the moon around the gas giant is the same as the orbital plane of the gas giant...
The lunar phases describe the form we perceive the moon having based on the light it reflects from the sun while being partially turned away from us. Q: Can we abuse science to make the moon have ...
I have a habitable Earth-like moon that orbits a gas giant. This moon is inhabited by a pre-medieval civilisation that has spread out across just one continent. The inhabitants of this civilisati...
Like, if you massively accelerated the Moon's orbit or propelled it somehow so that it moved from one side of the Earth to the other in a very short period of time, what effect would that have on t...
Sea levels are rising due to global warming. The Moon brings tides that also rise the sea level. If we destroyed the moon could this problem be solved? Would it have other consequences?
There is the strong theory that the Earth and the Moon were part of the same core at one point. This would lead one to believe that there are precious minerals under the surface of the Moon. Metal...
I'm imagining six moons orbiting a single large planet along the same, circular path. Each moon is at the L5 Lagrange point of the one "ahead" of it, and at the L4 point of the one "behind". I re...
So we harness energy from the sun using beams, right? Well what if we were to harness energy coming off the moon the same way? For those long winter months when the sun is rare we could use this to...
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...
The Hollow Earth theory is/was a pseudoscientific idea that our world is actually on the inside of a large sphere. The "sky" points inward towards the center, where the "Sun" (a light source) is, w...
For my story I am working on, a peaceful alien race that is studying Earth wants to terraform the Moon by building a giant sealed dome over its entire surface, then they will create forests, desert...
Would it be possible for a moon that receives a lot of tidal heating from its gas giant parent planet like Io to develop intelligent life? Assuming moon is big enough to support an atmosphere and i...
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 ...
Would it be possible for an asteroid in solar orbit to go near enough to the Earth that the Earth's atmosphere slows it down into an orbit that is, aside from its low perigee, stable without using ...
In the story I'm writing, humanity has cracked FTL travel by compressing a chunk of matter outside the craft into a short lived, gravitationally weak black hole that leads to a higher dimension (kn...
In my fictional world I have selected all parameters to maximize the Hills Sphere of my planet. The planet has three times Earth's mass and it is located in 2 AU from its star that's 1.4 times more...
Would scientists on the other side of blast survive in a bunker? I got an alien using telekinesis abilities to move Moon with the speed of " 1 hour till collide from the moment Moon left the orbit"...
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...
Would it be possible to move Ganymede into Mars' orbit causing them to fuse together like the two proto moons of earth? The new planet "Marmede" would have a mass equal to 13.2 % of Earth. Ho...
I have an exomoon that orbits close enough to its planet that it has notable geological activity. I would like to limit active volcanoes/geysers/lava lakes/etc. to at most, a couple dozen areas on ...
I know that on a binary planet you would have planetary eclipses (basically like a solar or lunar eclipse but with planets instead of moons). If there also is a moon, things would be much more comp...
I have a terrestrial moon that I would like to have spectacular and frequent lightning storms. What atmospheric compositions and conditions could cause this? Tools The moon orbits a 21 earth-mas...
A moon is, fundamentally, a rock that's caught in the gravitational field of a bigger rock (a planet) and drawn into an orbit. Some of Saturn's moons, for example, are speculated to be debris from...
According to this Reddit conversation, the detritus around a planet tends to form into a single plane located around the equator given enough time. How long does this process take? Suppose a planet...
If the moon started to move closer to the earth, for e.g. one meter per year, I suppose that it would be accelerating towards the earth and then, eventually, will crash to it. I suppose that if it...
Imagine a scenario where the moon is not tidally locked with one side facing the earth but where it is able to rotate about its own axis. This could be due to a larger distance from earth or a mild...
How stable (or possible) would binary moons be, (Luna-sized or possibly slightly smaller) rotating around an earth-sized planet? Edit: Thanks for the questions! And thanks for the welcome! My...
Could these moons be tidally locked between them or would they get locked to Earth? What consequences would the orbital cycle of these two moons have on Earth's surface?
Approximately how likely is it that a tidally locked planet would have a long term natural satellite, and where would that satellite most likely be located? What I've so far researched (and puzzled...
I've been trying to come up with a scenario in which space stations and lunar bases are established but are considered controversial. I sort of figure that if corporations started mining the moon t...
The host star for this hypothetical system is 1.05 (M☉) The gas giant is 20 percent more massive than Jupiter and orbits at 1.40 AU, now I need to know if these three orbits are stable around th...
If yes, what are some possible ways they could break through the ice and explore the surface?
Is there a way for a moon to usually appear relatively similar to our own moon, but occasionally appear much larger from the planet's surface without causing natural disasters due to extreme gravit...
I have decided to change the numbers to make it easy on Hohmannfan. These two planets, for all intents and purposes, are identical to Earth, with he moon replaced by another Earth. So now the quest...
So I have a fictional world where I have three moons orbiting this planet. I've used this web site to try and figure this out but I wanted to ask this question myself. My planet (a little bigger t...
