Atos System Redux

[Bill3000]

Time for some actual mathmatical work.Not including the atmosphere, here are physical factors that would affect a planet's habitability (regarding life)- Star's Power Output (Luminosity, affects temperature/color of star and obviously of the planet, excluding atmospheric conditions)- Distance from star- Gravitational field (acceleration) near planet's surface (g_surface is proportional to density times radius of planet)- Existance/Non-existance of Geodynamo (Creates magnetic field of planet, plate tectonics, helps protect against cosmic radiation)- Angular Velocity of planet (rate of spin, day length, duh)- Axis tilt angle (variation of seasons)- Eccentricity of orbit (how its distance from the sun will vary if not a perfect circle, which is very improbable to have)- Radius of Planet (Don't want to make it to the Schwarzschild radius of the mass )So if we want to have more than one actual habitable planet, we'd need to fit it in these catagories. Obviously this would be hard. There's only one habitable planet in the Sol System, so of course it would be hard. Let's compare Earth and Mars. First of all, obviously part of the problem of Mars currently not a Terran planet is its distance from the sun, but it also lacks a geodynamo and is smaller than Earth. A smaller planet means that it has less of a hold on the atmosphere. Also, when it could have been considered habitable, the luminosity of Sol (our own sun) was greater, (more power) which would have helped it as well.One more thing, regarding the star itself. Luminosity has a relationship with the radius, temperature, and mass of the star:L/L0 = (R/R0)^2*(T/T0)^4 ~= (M/M0)^(3.9)Where L is the luminosity, R is the radius of the star, T the surface temperature of the star, and M the mass of the star.Plug R0/T0/L0/M0 for the radius/etc. of our own Sun, and you have a relationship. So if we change the mass of Atos, we can increase the luminosity of the star and probably give us a slightly higher habitable range.

Tarsica was originally designed to be a moon of Momiji for an RPG. I'm not aiming for complete realism here. This is just for fun.Or should we get into the physics of having flying islands and elves? Useless art is simply tolerated vandalism. I am a vandal.

[Gryphon the Pure]

Well, we could have another habitable planet closer to the sun with a solarsynchronous orbit (no rotation) and a weak atmosphere, such that it could support life on the dark side of the planet from the radiant heat from the planet's mass and any reflected by the atmosphere...meanwhile any technology on the planet could likely subsist primarily on remote solar collectors on the light side of the planet.P.S. Warvoid, your Tarsica seems a bit unbelievable to me. If the moon has a weak atmosphere, I should think it to be at least as warm as Micras, being on the same orbit -- especially if it has plentiful amounts of H2O to serve as buffer in place of the strong reflective atmosphere of a Mangara planet.

Generally things like magical creatures are explained by magic.If you want to explain Tarsica's climate as by magic... go ahead. The moon of Micras is already suggested to have some sort of divine influence by several cultures in Shireroth at least, including the Lunatics and the Halluci.But I really want to steer away from explaining everything in our system by magic. I want to have some semblance of realism. At least if we're to have magic, we can make it realistic magic...For example, we could say mana is radiated from the sun in waves, like ripples in a pool. Micras' orbit could be situated near the peak of one of those waves, but since Tarsica orbits Micras, it picks up more mana than Micras, which since there are no mages stimulating the mana, it stagnates to cold energy (the natural form of mana, to differentiate it from simple energy whose natural form is heat).Closer to Atos, there could be a wave or two with higher strength of mana, and farther from atos, there could be mana waves of weaker strength.Of course, not every orbit would lie at the peak of a wave, so there could be planets with no mana at all.

Stupid ImageReady doesn't export to animated GIFs, so I'm stuck with a 200x200 flash file.If I had known I'd be exporting to flash only, I'd have made it bigger... I only made it smaller so I could link it in an image tag. Stupid ImageReady.

Uh, ok, I click it but it does nothing... O_o Useless art is simply tolerated vandalism. I am a vandal.

[Shyriath]

Maps? And globes? O cruel temptation! Ye who make the worlds of the Atos system know truly how best to torment me, to make worlds and then to say, "look but touch not with your claims!"...Don't mind me, I'm babbling. I do like the maps, by the way.Quote:If the moon has a weak atmosphere, I should think it to be at least as warm as Micras, being on the same orbitMagical explanations aside, this need not be the case. Earth (and presumably Micras) would be much colder than they are if they had thinner atmospheres, because the atmosphere traps enough heat to keep us all from freezing. If... Tarsica?... has a thin enough atmosphere, particularly a low concentration of greenhouse gases, then being in the same orbit as Micras won't keep it from being significantly colder.

[OctaviusMe]

Perhaps we could have the next planet after Micras as an ice planet, that started out similar to Micras earlier in the life of the Atos system but eventually became too cold to maintain liquid water because of its distance from Atos. Smaller than Micras, like maybe around 1/2 to 2/3 the diameter.Ever since you guys have started talking about the Atos System, I've been getting ideas, so this'd be mighty convenient for me. I'll get to working together a more detailed proposal for it, maybe even suggesting a name while I'm at it.

Good news, people. I have indeed found out the old original JASO post, at the Grand Archive. ( p200.ezboard.com/bthegrandarchive )Thank the gods for Comrad Cromrien, despite his current Apollophobia. Quote: Sun: Aton (type: G3)1. Chrono (type: V)2. Micron (moons: Atropos) (types: M)(size=1.0)3. Inferia (type: A)4. Indigo (moons: Plateau, Ivory*size=.1*) (type: W/M)5.

Replacing Monkey with Momiji would be good, since the slot is "earthlike".Also, ditch Yavin and NI. We don't want the Star Wars and Monty Python lawyers after us. Indigo can stay (it only means blue after all). Inferia can stay. Albeit I called the PRH Infernius. I believe we already agreed Gottagobye stays, as well as Dyson.Chrono is lame. That has to go.

Chrono is cool imho, but its not a good name for a planet
