Let's say hypothetically that we took our stock solar system and replaced the 4 gas giants with a low end red dwarf star like Proxima Centauri, giving the two stars roughly 15 AU of separation (and leaving the inner solar system unchanged).

How different would the climate on Earth be because of this? It would still receive the overwhelming majority (i.e 99%) of stellar radiation from the main sun, with the other sun being just a bit brighter than a full moon.

OK

no difference

Surprisingly, this wouldn't necessarily destabilize Earth's orbit.

To answer the question: Proxima Centaui luminosity = 0.0017 sols. That's basically how much less light Earth would receive if it was orbiting Proxima at 1 AU. At its closest approach to Earth at 14 AU distance (when they are on the same side of the sun), it would be 196 times weaker than that, so 0.00000867346 sols. That is an absolutely negligible contribution. If a planet was in orbit around Proxima alone at a semi-major axis of 14 AU, it would be colder than a witches teet.

I unironically would love to see a speculative alternative history of the American space program and its missions to the red dwarf.

Just for fun I'd have two planets orbiting the dwarf, including one in the habitable zone with water.

Is that an actual saying? I thought the retard said it in the book because it sounds stupid.

What would the consequences be towards human belief systems and astrology? Would people categorise it as an entirely separate star, or just consider it a really big planet?

It would look like a lightbulb in the sky.

It would be treated just as a very bright star.

They would take about 80 years to orbit each other.

It would just look like a star. It would probably be treated similarly to another planet until telescopes.

I think it could do the opposite, and make people realize that the sun is just one of the stars.

For a long time, peple didn't know the difference. To wit: Antares is "anti Ares" - opposing Ares which we today know better as Mars.

IDK as much about astro as you do but wasnt proxima centaury classified a flare star and the excursions in intensity were said to be orders of magnitude and emissions were heavy in UV and even xray ? When looking at the nunbers you gave 'several orders of magnitude' might be getting somewhere into the territory where it could cause disturbances when flaring.

Only if you're on top of the thing, close enough to receive liquid water temperature type energy
