Moons Beyond the Solar System

Most of the planets in the Solar System have moons. We have discovered almost 200 in our Solar System alone, and so we expect that the Milky Way is teeming with moons- perhaps more moons than planets and stars. With this many, it greatly increases the number of worlds in the galaxy which could support life- and so we are keen to find them. However, they are so distant and dark that detecting extrasolar moons, or "exomoons", is a tremendous challenge.

Yavin 4, the home of the rebel base in Star Wars: A New Hope (1977), was moon orbiting a gas giant, a red one. I dont know what the scientific thinking was on habitable moons in the mid-70s, but it was a great choice by George Lucas.

[@owen5640]

I always thought that was a great choice by sci Fi writers to have stories set on a moon, rather than a planet. Pretty sure star trek did that a few times.

[@ATemplarIGuess]

I prefer the look of the sky on moons to the look of the sky on planets

[@sjeason]

As much as I love the idea, there is literally no way that Yavin IV would be habitable at all. Yavin is said to be around four times the size of Jupiter, and Yavin IV orbits very close to its parent as you can see in its sky. Orbiting a planet that size and being that close would make Yavin IVs surface pretty much entirely molten lava from tidal heating, and the moon itself would probably not be spherical, most likely being stretch out at its equator. So Yavin IV doesn’t work Forest moon of Endor does though, its far enough away

[@SquirrelASMR]

You also had to go to a forest moon to hunt ewok meat.

[@SquirrelASMR]

I'm not sure if the habitable moons would be more like binary planet systems than moons. Some scientists want to consider the moon and earth as a binary system, because the moon to earth ratio is bigger than for any other planet's moons

@Hard Water very sorry that you seem so deeply affected by his desire to share his beliefs on a subject. I've noticed that conservatives have this very interesting way of making sure that everyone in the room knows just how much they liked someone "until they got all political," like they just can't help but mention that being a dirty liberal is the reason why someone is no longer worthy of their patronage. It's really rather performative and probably doesn't accomplish the goal that you think it accomplishes. I say this as a former conservative. I'm also -- before you try to make assumptions -- not some outraged hyper-liberal. I simply think that a person should be expected to say whatever they like on their platform, and I can follow or not follow without making a production of it. Inb4 random insults or nonsequiturs, since those seem to find their way into KZbin comments whenever there is a disagreement.

[@dat1pengu1n]

yeah

[@austinravn7759]

To my understanding, gass objects form precisely becuse they are massive to hold large amounts of gass, but i always could be wrong

[@sea_space]

Gas giant planets accumulate their gas after formation, because they form beyond the boundary of their system where ice can exist. This ice adds loads of extra material for the formation of the planet, making it so massive that it pulls in gas to give it its gas envelope. The reason they wouldn’t form naturally around moons is because moons form from leftover planetary material- if there is enough in the area to form a gas giant, then chances are it will be a planet in its own right!
