For story reasons, I need my mages to convert a moon on a collision course with their planet into a ring around the planet. The only thing they can do is hold the moon still. They can't do so ...

Looking most specifically regarding the moons around Saturn, Jupiter, and Uranus. I've been unable to get a concrete answer on this through various sources. I've actually read several articles briefly ...

What additional difficulties might the inhabitants of a gas giant moon face when attempting to launch spacecraft beyond their moon's orbit, especially beyond the planetary system? I presume that they'...

For story purposes, I'm trying to determine what would happen if a small moon-sized object crashed into an unmovable barrier surrounding a planet. My goal here is to eventually get a ring surrounding ...

I recently had an idea, and it involved moons. Excluding gas giants, roughly what percentage of planets in the habitable zones of their stars would have large moons like Earth does, as opposed to Mars ...

My planet, is roughly as big as Earth, but has two moons. The first moon, Luna, is essentially the same as Earth's moon, but the second, much, much smaller moon, Selene, actually orbits Luna. Selene ...

I'm working on creating a world with three moons, all with different sizes and different orbits. I'm wondering what effects this would have. How would the tides be affected, obviously, but also would ...

Consider a planet identical to Earth except that it has no moon. How long is the complete day-night cycle on this planet? I've heard that having no moon would speed up the planet's rotation, ...

In honour of the full moon an odd moon question for you all. The idea is to create a situation in which the inhabitants of a world believe utterly that the moon only exists at night. I'd also like to ...
