Astronomy of Candarion
You are forgetting the OG 6th planet:
Color: Hot pink
No one likes this one because it smells bad.
Just wondering, but since planet 5 has an orbit which takes it close to the functional north star of Candarion, wouldn't it indicate that the planet would have an orbit severely misaligned from the ecliptic? Gas giants which deviate this way would be phenomenally rare, since impactors wouldnt collide and throw the planet like any terrestrial bodies, and gas clouds would be compressed into sufficiently large protoplanets only along the ecliptic... The only acceptable explanation by modern astronomy is an extrasolar "rogue" planet got caught up in the sun and was captured. This explanation makes the sixth planet a statistic unlikelihood, but not out of the realm of possibility.
tl,dr; planet 5 is fucky, is that okay?
Also even if we have other planets in our solar system, nobody in Candarion would realize they are planets, right? It would just be a "huh, those 5 stars look and move really weird but we don't know why" sort of thing right? Or does our tech limit allow for good enough telescopes to actually observe these planets and discover their true planetary nature?
@chewypudding I believe planets were identified and observed first around the 16th and 17th centuries if I recall correctly, with Galileo Galilei. If we are willing to make an exception for us to be able to identify planets in our 15th century era, considering this is not Earth but rather a completely different world, I would accept that. Even with the use of magic of sorts. I don't see it being anything that would be of any real significance / lore breaking.
I don't think the time period should make a difference here.
The ancient Greeks and beyond knew of the planets unto Saturn. It wasn't until the invention of the telescope that the later gas giants were identified, but the idea of planets and their relevance to earth was well documented even in the Bronze Age and before
@ielis Yes, this is correct, good point. I think we should probably cut that bit of the lore, then.
@ChewyPudding @Darius The five innermost planets (Mercury through Saturn) have been known since ancient Babylon in 2000 BC! While planetary physics may not have been fully understood, the ancient Greeks had several heliocentric models of the solar system and knew that the planets were orbiting bodies. The color of planets can also be distinct enough to differentiate them from stars (eg. Mars). So, as Seppy said, we don't need telescopes to be able to identify and study planets, though of course we wouldn't expect anyone to understand the finer points of their physics and compositions.
As Beiji said, the 5 closest planets are easily observed and distinguishable from stars using the naked eye. In fact, the word planet comes from the ancient Greek planētēs ‘wanderer, planet’.
There won't be any lore conflicts with the above suggestion.
I suppose it's a matter of semantics. As far as the tech, telescopes are somewhat complicated devices and require specific advancements in glass making for the lenses. I am not entirely opposed to telescopes because magic , but I would advise against anything later than Galileo for thematic reasons.
For a lot of cultures through history, the planets were just as you said - wandering stars. I don't care particularly much how your realm interprets what they see. Do they consider them fundamentally different than the other stars? That's fine. Are they just weird moving dots? Also fine.
That sounds cool! Most this stuff is irrelevant to any of our lore, but why not have a captured exoplanet in our solar system. I like the idea.
Unless anyone has any last minute contributions, I am willing to accept this as the final arrangement and description of planets in the Candarion system.
