Mapping Sol

[Baron Munchausen]

Heh...

Too much oxygen is poisonous because we've evolved in this atmosphere which is 70 percent+ nitrogen. A (nearly) pure oxygen atmosphere would not necessarily be impossible for life to exist in, though unlikely in 'real life' because free oxygen is chemically unstable. It's the presence of life that maintains the current percentage of oxygen in Earth's atmosphere now. It would all be soaked up in chemical compounds within a few million years without constant renewal by plants. Many simpler life forms on Earth today could handle a nearly pure oxygen atmosphere, though.

It's much the same for CO2. We humans would die in an atmosphere of more than 4 or 5 percent CO2, as I recall. This is not a universal constant but simply a function of how human physiology turned out. Lots of simpler animals can handle more than 4 or 5 percent CO2.

You want to map the sol system only??? Got 10 minutes to spare? Now if you want to map the closest 100 systems that would be a really cool project! (one I've thought about doing myself but that map editor ... )

yeah, to high oxygen = bad.

Should earth be a CO2, or an O2 planet(Technically its mostly CO2, but we use the O2, at least I think its mostly CO2).

Should there be 8, 9, or 12 planets?

How many moons should be included? Would Phobos and Deimos be included, or would they be considered asteroids?

Earth should be an Oxygen planet - Medium sized IMHO.

IMO, there should be 9 Planets. Quaoar is technically a Kuiper Belt Object. Although Pluto and Charon are also Kuiper belt "objects", but they've been classified as a planet for a long time, so should be treated as a planet.

The larger moons should be included IMHO: This includes The Moon, Charon, all larger moons of Jupiter and Saturn: Europa, Ganymede, Io, Titan, Etc. Deimos and Phobos shouldn't be included in the map, since they are asteroids.

Just my two cents.

You could always make a random map and just move the systems around and rename them.

Yea that would be cool. Now can someone else do it?

Well, SE4 isn't exactly made to represent solar systems very well. There's no real sense of scale; IIRC, if you made a scale model of our solar system with the sun the size of a basketball, Neptune's orbit would be about a mile out. And in the stock files, there are only five planet sizes (Tiny, Small, Medium, Large, Huge)...

I don't recall the specifics of the atmospheres for all the major moons -- major as in they're usually noted, not because they're large; thus Phobos and Demios, and Charon would count, even if they are barely larger than an asteroid -- but it would go something like
tiny rock/none
small or medium rock/methane (orange picture)
small or medium rock/oxygen (Earth-y picture)
small rock/carbon dioxide (red picture)
huge astroid field
huge gas/hydrogen
large gas/hydrogen
large gas/methane? (not sure on Uranus' composition)
medium gas/methane? (not sure on Neptune's either)
tiny ice/none

All the moons would be tiny, and the gas giants should have asteroid fields in addition to moons (rings). That's probably as close as you're going to get.
