Why does Tylo airless but then Duna has an atmosphere?

[Gradysadome]

Even though Duna has an atmosphere, it cant generate a magnetic field and is smaller than Tylo, yet Tylo is airless and should have a magnetic field meaning that it should be able to capture an atmosphere but is airless.

(Solved i guess idfk)

because reasons

But seriously, this probably has less to do with realism and more with “gameplay challenges”

You could say Jool when in formation likely took all the gas available from Tylo, and Laythe was close enough to steal some, from Jool.

Magnetic fields are for shielding against cosmic radiation. Atmospheres are layers of gas that adhere to a planet through gravitational attraction. Duna may have layers of gas to form an atmosphere but it is airless, as in the gases can't be used for respiration. Layers of gas aren't captured by planets unless they are super massive and have such great gravitational pull that they steal from a near planet that has an atmosphere. Atmospheres come about through molecular and chemical reactions that cause the substance of a planet to form elements and compounds that are most comfortable in a gaseous state based on the amount of heat generated by the near by star or by the thermal inner of the planet. If the planet does not have a suitable makeup of elements and conditions then it won't produce an atmosphere.

The real reason is ........ it's not real. It's a game.

It is not a simulator of what a real system would look like.

The Julian system should be unstable and have only Tylo or Laythe in it.

Make your own reasons why.

Maybe Tylo was an errant planetoid that came too close to Jool and had its tenuous atmosphere ripped away by tidal forces.

Tylo could have been destroyed and survived only by random luck.

Then it got slowed down by Laythe to achieve a capture by Jool and got in the resonant orbits we know.

 

Or perhaps it used to orbit very close to to Kerbol and had it's atmosphere boiled off before a close encounter with Eve that sent it on a very close encounter with Jool.

 

Enjoy the game.

Makes sense TBH, thanks for answer

WELL NOW THE NEW QUESTION IS WHY IS LAYTHE BREATHABLE /J

[Martian Emigrant]

Well.....

Laythe's atmosphere.

We don't know that it contains oxygene

We know that it can oxydize fuel (We don't know what the "Fuel" is) and not kill Kerbals but we don't even know if Kerbals breathe.

We know nothing of their alien physiology.

We know they can't Live in vacuum or be exposed to Eve's atmosphere.

Whatever Laythes atmosphere contain could be the bi-products of life, volcanism, outgassing of the chemicals in the crust or core.

Maybe that atmosphere is temporary and will escape to space in the next 1000 years.

@Gradysadome

I see from your reply that you didn't actually want a real world answer. (Could have saved some time if you had made that clear.)

So 1: The programmers just felt like it.

Or 2: They wanted to give players many different environments and challenges so as to stimulate their problem solving skills, so they felt a sense of achievement when they finally came up with a solution. This also serves to increase the long term playability of the vanilla game.

yesss that is my personal (and yours, I guess) personal theory on "why laythe be laythe????"

and why?

please look at the large crater found on laythe (look at the wiki biome map)

that could easily rupture some internal ices and gas into space, or a atmosphere

I mean, ksp's system has changed a ton, maybe at some point when they were making concepts for it it did have an atmosphere but changed it for the second reason, i mean, gp2 was gonna have a moon covered in some sort of "fluff"
