UmbralRaptor changed the topic of #principia to: READ THE FAQ: http://goo.gl/gMZF9H; The current version is Darboux. We currently target 1.3.1, and 1.4.3. <scott_manley> anyone that doubts the wisdom of retrograde bop needs to get the hell out | https://xkcd.com/323/

I have tweaked the initial rotations, which is important to you
<GregroxMun>
still left to do: atmospheres, new biome maps, science definitions.
<GregroxMun>
oh
<GregroxMun>
and asteroids
<GregroxMun>
I think I can do asteroids now.
<GregroxMun>
egg, UmbralRaptop
<GregroxMun>
what do you think of trojan asteroids around the planets?
<GregroxMun>
are they particularly likely?
<UmbralRaptop>
My gut instinct is unlikely. But some simulating would be in order.
<GregroxMun>
https://i.imgur.com/djsonT3.png flaw in my plan: yes comets should be more common, but they shouldn't be as easy to track as nearby asteroids
<GregroxMun>
so far I've tracked 6 comets and 1 transplanetary asteroid
<GregroxMun>

<GregroxMun>
what do you think of trojan asteroids around the planets?
<GregroxMun>
or egg|phone|egg ?
<GregroxMun>
I think I shall have to make the SLIPPIST version of the atmospheres of b and c a little nerfed compared to the realistic version
* UmbralRaptop
ponders poking MERCURY6.
<GregroxMun>
though I trust the TRAPPIST-1 conversion will still include realistic atmospheres
<GregroxMun>
so I'm going to use 15 atmospheres for Beta and 5 atmospheres for Charlie
<GregroxMun>
(analogous to Jool and Eve respectively)

!tell GregoxMun same as Umbralraptor, bodies other than the planets are a mess because there are so many planets that will nudge them around; I don't think you can get trojans etc.
<Qboid>
egg|zzz|egg: I'll redirect this as soon as they are around.

GregroxMun: egg|zzz|egg left a message for you in #principia [11.06.2018 07:44:12]: "same as Umbralraptor, bodies other than the planets are a mess because there are so many planets that will nudge them around; I don't think you can get trojans etc."
<GregroxMun>
oh
<GregroxMun>
oh
<GregroxMun>
ok
<GregroxMun>
what about asteroids in circular orbits between the planets?
<GregroxMun>
or would inclined tend to be more stable?
<GregroxMun>
Or do you expect the only asteroids would be beyond the planets?
<GregroxMun>
Another question, really one more of preference than science
<GregroxMun>
given that the terrain of Beta is more "easter egg" than "feature," should the biome map reflect the terrain of the planet or the cloud map?
<GregroxMun>
oh you know what
<GregroxMun>
I should make sure I include a distinction in the day/night biomes
<UmbralRaptop>
Unsure, but I suspect that orbits between the planets would tend to get cleared out. A handful of small ones in unstable orbits, maybe?
<UmbralRaptop>
Also, day/night biomes sound nifty and appropriate.
<egg|zzz|egg>
GregroxMun: anything between the planets is not a friendly place
<egg|zzz|egg>
this is very packed
<egg|zzz|egg>
also same as UmbralRaptop, I like the idea of day/night biomes
<egg|zzz|egg>
GregroxMun: I guess the biome map should reflect the climatological features, so the subsolar mess, the equatorial band of wind, etc., that's what you study when you're in space low above them
<UmbralRaptop>
Offcenter hotspot, substellar ocean, etc. Bonus points for punny names.

new findings: if you give a star a biome map, it won't show up with the cheat menu.
<GregroxMun>
I think it should show up with KerbNet
<egg|zzz|egg>
star biomes? Ꙩ_ꙩ
<GregroxMun>
yeah why not\
<GregroxMun>
photosphere, sunspots
<GregroxMun>
*maybe* poles, just so you reward players who are silly enough to get into polar orbit of a star
<egg|zzz|egg>
sunspots are ephemeral tho
<GregroxMun>
not in KSP.
<GregroxMun>
I figure, on a tidally locked planet, it might be a lot more obvious that the universe is heliocentric.
<GregroxMun>
as soon as explorers visit the far side and observe the motion of the stars, they'll find out that Echo is actually rotating
<GregroxMun>
I imagine having large, close planets may also result in an easier measurement of parallax in order to find their astronomical unit
<GregroxMun>
speaking of parallax, the distance to the stars will be a mystery for a very long time.
<GregroxMun>
anyway once you find out that echo is rotating, and you can observe the spherical nature of many of the planets with the naked eye, you should be able to tell at least that the inferior planets are heliocentric
<GregroxMun>
you wouldn't have any reason to believe that the universe revolves around you when the only evidence for this is the outer planets, and even then it's in a way that doesn't look at all obviously geocentric
<GregroxMun>
and once you go to the far side and find that your homeworld is rotating too, it becomes obvious that it is a planet just like the others.
<GregroxMun>
Actually it may even be hypothesized that the homeworld is spinning before it's confirmed by seeing stars.
<GregroxMun>
because if you think the planets move in circular paths around the star because you think that's an elegant model of nature, then you might do the observations and mathematics to conclude that the planets do travel in regular, circular orbits, as long as the homeworld does as well
<GregroxMun>
it will be even more obvious if parallax measurements are done to find the distance to the planets, and to measure the size of the planets--they would turn out to be roughly the same size as the world.
<GregroxMun>
if you can observe sunspots with the naked eye, it may even be the absolute default for any culture to assume the homeworld revolves around the Sun, assuming the sun's rotation period is significantly longer than the planet's orbital period.

I'm really going to just have to redo Echo
<GregroxMun>
it isn't consistent with the other planets anymore.
<GregroxMun>
At least it needs a new ice cap map, but honestly a lot of the terrain can be changed.
Hypergolic_Skunk has joined #principia
<GregroxMun>
My initial conception of Echo was that it was a planet that is cooked on one side, no water, and frozen on the other side. Any bodies of water on the near side would get moved to the far side and snowed down.
<GregroxMun>
I now know this isn't how tidally locked climates work
<GregroxMun>
Also Echo should be a little chillier
<GregroxMun>
Does anyone here want to help with writing science definitions for SLIPPIST-1?

Given that the system is so compact

I wonder if asteroids would be naked eye objects
