Solar System dynamics discussion thread

31505 Would it be stable for a small planet to exist in the L4 or L5 points of the Earth, or possibly other planets too? In his spectacular explanation about Lagrange Points and their stability Watsisname mentioned and linked an article just about this. The last equation of that article yields the ...

Science and Astronomy Questions

31495 By what process would the moon have formed? Would it have been captured and forced into this orbit? It probably wouldn't look like our moon. Capturing a large moon like this around the Earth seems very unlikely.  Something would have to slow it down as it was passing Earth, or else it would j...

31478 What if the moon revolved around Earth in the opposite direction? Getting closer each year rather than farther? 31483 No, instead it would get further away faster!   Since there is a bigger difference between the rotation of Earth and the rotation of the Moon around Earth, friction will also ...

31395 What if the other side of the moon faced the Earth rather than the one with he Lunar seas? I think this would raise the question of "how did it form/evolve that way?"   A popular idea is that the far side of the Moon is much more cratered than the near side because the Earth shields...

31186 Lets say you have a planet that is like Earth. But it's a moon orbiting around a larger gas or ice giant. How would this affect plant life on the near and far sides, how would they be different from one another? Or if you have a planet with multiple moons, would that affect plant life? Could ...

Can someone make a procedural solar system that is reversed, with the gas giants first, then the terrestrial planets?

Quick Question about Realism

Does it really make sense to have massive moons and ice giants in orbit of a gas giant so close together like in solar systems? In my mind they should usually be smaller and further apart.

The question is, which of these situations would you prefer to live in? Blue or red. Blue or red pill, if you will. I think the best stellar classes for habitable planets are G and K. I can't tell which one of those is the best. The Sun releases a fairly high amount of UV radiation and, if wasn't f...

What would a reverse solar system look like? With the Gas giants being in the places of the inner planets and vice versa?

31181 If we had an Earth around a hotter sun in a habitable, say an F, A, or O star, would we get sunburn easier? Yes, we very probably would, for just the same reasons.  The hotter the star, the larger the fraction of its light that comes through UV, so even if we kept the total amount of sunlight...

I see. That's very interesting! Quite useful for worldbuilding purposes as I feared that planets around hotter stars in habitable zones would also be brighter, and thus an unpleasant place to live. Even the hottest stars, maybe 0 type stars would still have the same apparent brightness as our sun bu...
