You design life and a system

[Cha (Waluigi)]

I do not think so? it would be ‘gentle’ in comsic scale but for life? gigantic even if it was a very slow crash relative for us

I imagine cultures will develop 2 sun gods and not one.

[Cha (Waluigi)]

Yeah, I doubt a single sun god will be common and if it exist it likely would be a case of it is the god of both of the suns not a sun

There might be some extra weird stuff going on if one of the inhabited planets also has 2 major moons

@aah31415

one of the inhabited planets also has 2 major moons

Or many asteroid moons…

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

Major moons could sweep these off the planet’s orbit before a sapient species arises…

[AnthropocenianAge (𝒜𝓇𝓉𝒽𝓇𝑜𝓅𝓁𝑒𝓊𝓇𝒶 𝓌𝒶𝓃𝓉𝓈 𝓉𝑜 𝑔𝒾𝓋𝑒 𝓎𝑜𝓊 𝒶 𝒽𝓊𝑔!)]

It is also possible that all of the asteroid moons eventually coalesce into a larger moon, or ring system..

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

Rings also fade away gradually.

@aah31415

also fade away gradually.

Such is the nature of things.

[OceanPlanet]

I imagine this would make methanogenesis work and even use oxygen to make methane.

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

We haven’t decided to add life there yet though.

[OceanPlanet]

Okay yeah, so the 1st planet’s complete.
This is it’s characteristics.

• It’s small at about 0.7 rE.
• It’s light at about 0.3 mE.
• Has a very elliptical orbit.
• Has a small moon (0.3 rM) which is a remnant of a former planet, which now remains an iron core.
• Has a methane and oyxgen rich atmosphere.
• It’s internal structure is like Earth and has a strong internal magnetic field.
• Is hot at about 30-40°C.

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

Won’t methane and oxygen create a flammable atmosphere?

[OceanPlanet]

Maybe but onto the 2nd planet.

• Semi-oceanic planet (2O)
• Earth-like planet (3O)
• Oceanic planet (4O)
• Hycean planet (4Oh) (this means already a hydrogen-rich atmosphere.)
• Icy terrestrial (2T)
• Terrestrial planet (1T)
• Gas dwarf (G1)
• Gas giant (G2)

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

Do we get to specify much about gas planets if they are chosen?

[OceanPlanet]

Firstly, yes, your options are:

1. Ice giants
2. Normal gas giants
3. Alkaloid giants
4. Gas dwarfs
5. Ammonian giants
6. Vapor giants

And secondly
There’s another poll post.

Radius of the 2nd planet.

• Mini-Earth (0.2-0.8 rE)
• Earth-like (0.8-1.2 rE)
• Super-Earth (1.2-2.5 rE)
• Maximal Super-Earth (2.5-4 rE)

Mass of the 2nd planet

• 0.1-0.8 mE (light planet)
• 0.8-1.5 mE (Earth-like mass)
• 1.5-3 mE (massive planet)

Orbit of 2nd planet.

• Very elliptical orbit (for crazy seasons)
• Mild elliptical orbit
• Near-circular orbit (like Earth)

Temperature of the 2nd planet.

• Lukewarm (25-20°C)
• Cool (20-5°C)
• Cold (5 to -10°C)

Do you want a moon on the 2nd planet?

• I want the winner moon
• No moon

Internal structure of the 2nd planet.

• Crust, mantle, core.
• Crust, mantle, outer core, inner core. (with induced magnetosphere.)
• Crust, mantle, outer core, inner core. (with internal magnetosphere.)

Atmospheric composition of the 2nd planet.

• Methane-rich atmosphere
• Oxygen-rich atmosphere
• Carbon dioxide rich atmosphere
• Earth-like atmosphere
• Hydrogen-rich atmosphere
• Mixed atmosphere
• Sulfuric atmosphere

Is there a mass limit for just how massive can the planets of the system get collectively?

[OceanPlanet]

Well, if it’s an individual planet, then at about 10 mJ (Jupiter masses), the core is heavy enough to fuse deuterium into helium, this will make it into a star.

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

And collectively there is no limit below what you just stated would dictate?

[Cha (Waluigi)]

I mean there would be also the limit when the planet is just a gas dwarf from its atmosphere alone
