Q: Could a planet have a naturally occuring moon at one of its Lagrange points?

FrotzieWould it be possible for a planet to naturally have a moon or large natural satellite at one of its Lagrange points? If so would it then also be able to have a second moon that would be orbiting this hypothetical planet?

I think I stand by my comment on it.
I'm a little confused as to why this question was closed as unclear. . . Maybe it doesn't demonstrate a huge amount of research, but that's not a reason to close it. — HDE 226868 ♦ 23 hours ago
 
@HDE226868 I agree, I think it's pretty darn clear
Although I don't know if you'd call it a moon?
Theoretically Jupiter has asteroids that got stuck in it's legrange points, but by definition they aren't in orbit, and so aren't moons.
"That's no moon. That's just a planetoid that got stuck in L4."

Yeah, I'd agree with that.
 
@HDE226868 You might be able to tell me if my understanding is wrong; in a system with a ring of 9 solar mass stars orbiting a 1,000,000 solar mass black hole, the 9 stars are going to be putting out more radiation than a single 1 solar mass star, but that will only push the habitable zone out a ways, and any planets in that zone will likely be fine radiation wise (assuming things like magnetic fields are all in order).
I just want to make sure that the above statement is in line with the known science
 
I think so. . . If you've got a black hole that massive, it's going to have an accretion disk and some other structures around it that could be a couple dozen light-years across (fast-moving gas clouds, for instance); those might prove slightly problematic for life. But the stars should be orbiting far enough away from each other that each star won't influence the other stars's habitable zones, yeah.

A: Sandbox for Proposed Questions

AshMalign Science: An alternative origin for Grime's Graves Work in progress, ran out of time for now. We know that Grime's Graves in Norfolk was a flint mine that was exploited at least as early as c.2300BC

@HDE226868 In theory it would have to be a completely manufactured system, and might not have much of an accretion disk. What it would have is over 2,800,000 planets.

A: What is the theoretical maximum number of habitable planets in one solar system?

AndyD273This is based off the information found in the link provided by Juraj. The answer is 2,862,106 earths in the goldilocks zone How to get 2,862,106 earths in habitable orbits: Rules, they have to all be exactly the same mass. Multiple planets can be in the same orbit, so long as there are at leas...

Seems like a really neat setting looking for a story.

@AndyD273 One decent sized stray meteor and things get very interesting (apocalyptic) very quickly.
 
@James Giant meteors generally make things apocalyptic. I wonder how big it would have to be to disrupt planet orbits? Or are you talking shrapnel?
My current theory is that they fed everything within several light years that wasn't a planet to the black hole.
You might get something crazy like Oumuamua, but it's likely not going to be big enough to do much to more than one planet.

Anyone listened to the Lime Lighters song Max Goolis? It's hilarious, and full of puns.
 
@AndyD273 Right but if the orbit of a single planet wobbles too much it throws the whole system off...and that would be...messy.
 
@James True. Probably one reason why the guy who wrote the article it's based on to 400 rings of 2500 planets... give a bit more buffer.
Also, because 1,000,000 is very nice and round. Slightly less round than 2,000,000, but it is kinda fancy.

Afternoon.
 
@NexTerren Sup
 
@James Waiting for the day to end. You?
 
@NexTerren Same. And it is taking forever.
 
8:18 PM
It really is... I finished up a project, my project board is looking kinda barren, and the people who I would ask about new projects are all out of the office...
 
8:34 PM
@AndyD273 Chat saves the day.
 
@James Quiet in here too...
Don't have too much longer though
