1. ### How to calculate Earth speed of the Moon induced orbit?

I am thinking about the speed that earth has to have due to its gravitational interaction with the moon. I know that the moon's orbital velocity is approximately 1.022 km/s Now according to Newton's third law, the force is equal for both of the bodies meaning that F = m_earth * a_earth = m_moon...
2. ### How to calculate Earth speed of the Moon induced orbit?

It didn't work and I don't know how to do it.

4. ### I Research paper and sources investigating Earth's moons

As for the three-body system, when thinking about the collision/ejection of the smaller moon, would it be possible to have that happen after decades or thousands of years or does these events tend to happen quickly and within short time period. Isn't it possible to have some kind of a stable...

T Thank you for your answer. Maybe I didn't formulate myself clearly but that is quite what I am searching for. I understand that the number of possible moons can vary depending on the time frame and mass but I wonder if some researches such as the one I have mentioned in my post have been made...
6. ### I Research paper and sources investigating Earth's moons

I mean moons in the sense of spherical and big-mass bodies (that are detectable and somewhat visible). As for stability time, it should last for at least decades and not be temporary as in some passing asteroids or such. I have already read the article linked but I am wondering if there's some...

But they don't count as moons? I mean moons in the sense of natural satellites in sizes comparable to other moons of other planets. A moon with a stable orbit around earth and a known orbiting period.
8. ### I Research paper and sources investigating Earth's moons

Hi. I am looking for scientific papers, articles and/or even simulations that investigate how many moons it would be possible for earth to have and maybe modern theories about what these moons can be and look like (i.e what characteristics they have) if they were to exist. I have googled and...
