Gas giant ('s moon) orbiting a black hole? Unless someone else is interested I remain on gas giant moon, no star, low grav and dense atmosphere. Which are not contradictory, at least in the short term. Favouring low grav over dense atmos in case it matters.

Hot/warm, rogue gas giant with low gravity and dense atmosphere.
Basically a starless Jupiter/Saturn.

I kinda like a star. I'd like at least a small star. Red dwarf or something.

NO star might sound cool, but honestly it just means that we're playing on a Europa like planet. No atmos, just an artic ocean and lots of ice.

[Carnwennan]

A nearby nebula sounds cool, for the aesthetic imaginary sky. Orbiting a black hole would also be cool. But eh, what are the chances of life evolving on a planet like that, right? ((FEdit: Damn, ninjas)) Don't last long enough (the black holes) iirc. Rogue planet sounds fun-ish.

For the planet:

- Obscenely high tectonic and volcanic activity (volcanism get, diastrophism get, natural disasters get).
- Need moar heeet retention (+1 to dense atmosphere).
- Only maybe 30% water coverage, concentrated on the northern pole (not because it's colder or anything, just for reference). Ice sheets if it is too cold for liquid water.

Anything else specific to the planet? Makes it easier on the DM and such such.

Hmm?

Just because we don't have a star doesn't mean we're living on Hoth.
If we have a hydrogen-heavy atmosphere, the planet could hold enough heat to maintain liquid water.

(and according to *cough*the Polish article about rogue planets, if Jupiter was a rogue planet, its temperature in the upper parts of the atmosphere would be lower by roughly 15 kelvins. The part about hydrogen atmosphere also comes from that same article.)

Anyway, my point is that no star does not equal -100 Celsius all day, every day.

Okay, attempting to come up with a planet...

Kaon is a moon orbiting a rogue gas giant. It is located closer to the middle of the galaxy than Earth or the nightmace's planet, resulting in a perpetual dim sky. It is about two thirds of the size of earth, but due factors such as its density, a high abundance of xenon and slight leakage of gases from the giant, it has a thicker atmosphere than Earth's. Tidal forces and volcanic gases give it enough volcanism to have a healthy greenhouse effect. It is tidally locked to the gas giant, meaning one side recieves more reflected light but more radiation, while the other is darker but has a far safer amount of radiation. Its surface has only 50% water, but the oceans are fairly deep.

So, waddaya think? It's more pseudoscience ramble than actual science, but if it makes your spaceship fly...

EDIT: Dangit, five ninjas.

[Remuthra]

That sounds fine. I vote we play on the radiation bath side.

[Urist Mc Dwarf]

Radiation path sound is good for me. Does that mean we'll get more mutations?

[Mesa]

Disregard wenches moons, acquire gas giants.

Damaged DNA =/= Faster evolution

The only mutations that matter are the ones that get into the sexual cells. The others are all far more likely to just give you cancer or something. Therefore, we'd probably be submerged in mud permanently until we get a radiation-proof shell or something.

Perhaps we could make a migration?

Through space and a large radiation belt. Right.
