Idk, could a habitable planet have rings? They could also just have other planets visible in their skies. TRAPPIST has like 7 planets in that system that are tightly packed together.

Is there any connection to the capacity for a planet to harbor life and the possibility that it will have a moon?

>aliens on a Moonless planet
no such thing. no moons, no life.

>>16955536
moons make a molten core/magnetic shielding easier
some think life is more likely to emerge on a moon of a giant planet than a planet itself

>>16955565
Possible. Lots of problems. The more complicated it is to create life the less complex the life will be.

>Could a habitable planet have rings?
Yeah, why not? As long as it’s not as complex as Saturn’s where you are forecasted to have civilization ending impact events every week. Mars is projected to have rings in the near future.

It’s definitely possible for a moonless planet to have space exploration, it’s just gonna take a long time since they have nothing to test mechanics on. In theory, habitable planets smaller than Earth can do spaceflight very easily, while those super-Earths with 2x gravity? No one’s leaving their atmosphere.

Debatable. We have an incredibly small number of examples to work with.

Absolutely right about the size of planets affecting a civilization's progress. I sometimes wonder if this could lead to them discovering different technologies, or how it could lead a civilization away from physical propulsion into different forms of travel. Different circumstances, different solutions.

>>16955565
what's your sample size for that

>>16955385
the moon landing hasn't been necessary for sending probes to the other planets and moons of the solar system so no.

>>16955508
Earth had rings 500 million years ago

>>16955385
I don't know. but having a moon like ours is very helpful. its right there, we can see it close. so its just tempting.
its a good practice start to go there and set up a base, its close so a better chance to send help or pick them up if something goes wrong. and then after figuring that out, mars next.

>>16955536
Yes so far there is 100% correlation between a planet having life and that planet having a moon.

>>16955536
Yes. Tidal forced knead the crust and allows for an inorganic carbon cycle.
