Mapping Sol

Lord Kodos · #1 August 14th, 2003, 07:36 AM

The idea of this project is to make it vanilla, so it can be used with base SEIV maps. Sorry Fyron ^__^.

And how will we represent the Oort Cloud? And I say put a asteroid belt on Jupiter to represent its many moons.

No asteroids around Jupiter. Just add the 4 big moons, the rest are too small!

Just one asteroid belt between Mars and Jupiter is fine, you don't need to go crazy.

BTW, did SJ ever add my nice Sol planets?

moons go around planets. therefore, phobes and deimos are moons, yeah? makes sense to me.

maybe astroidal moons.

I am fairly certain that someone made a map of Sol a long time ago... try searching for it in the scenario section, or the old scenario archives (closed section) if it is not in there. It could be used as a starting point (less work to do that way

).

That depends on who's Sol planets are in the Planet Pack. Best way to find out is to go download it and see.

I think Phobos and Deimos are way too small (~25x15km) to justify their inclusion as moons, and since their is only two of them - it hardly justifies them being represented as an asteroid field.

If you included them, then you'd have to include the dozens of little moons around the Gas Giants...which is a little overboard IMO.

Look here.

Mercury

Quote:

Mercury is the closest planet to the Sun and the eighth largest. Mercury is smaller in diameter than Ganymede and Titan but more massive.

Asteriods

Quote:

The total mass of all the asteroids is less than that of the Moon.

Ceres is not as large or larger than Pluto. It is just barely large enough to have been rendered spherical and close enough to earth to have been clearly seen long enough ago for them to have originally thought it to be a planet. It has a raduis of 466 km.

Jupiter

Jupiter has four large moons, Io, Europa, Ganymede and Calisto. All except Io should be Ice. All Ice moons are believed to have a rocky core, but are icy on the surface (even Gas Giants have a rocky core).

Jupiter has no mid-sized moons.

Saturn

Saturn has one large moon, Titan. Titan has a radius of 2,575 km.

Quote:

Titan is about half water ice and half rocky material. It is probably differentiated into several layers with a 3400 km rocky center surrounded by several layers composed of different crystal forms of ice....
It is composed primarily of molecular nitrogen (as is Earth's) with no more than 6% argon and a few percent methane.

Saturn also has five mid-sized moons between 260 km and 765 km in radius.

Uranus

Quote:

Uranus' atmosphere is about 83% hydrogen, 15% helium and 2% methane....
Uranus' blue color is the result of absorption of red light by methane in the upper atmosphere.

Uranus has four mis-sezed moons from 236 km to 789 km radius, I do not think they'd even qualify as Tiny.

Neptune

Quote:

Neptune's composition is probably similar to Uranus': various "ices" and rock with about 15% hydrogen and a little helium. Like Uranus, but unlike Jupiter and Saturn, it may not have a distinct internal layering but rather to be more or less uniform in composition. But there is most likely a small core (about the mass of the Earth) of rocky material. Its atmosphere is mostly hydrogen and helium with a small amount of methane.

Neptune has one large moon, Triton, which is icy. It also has one mid-sized moon, Proteus, with a radius of 209 km.

Good table of moons, who discovered and when, distance from planet, size:
Moons Table

Just a suggestion, but I would dispense with anything under 1500 km in diameter, call anything between 1500-2499 km tiny moons, anything over 2500 small, and over 4500 medium (if such a thing exists, don't recall).

Moon(E), Europa(J), Triton(N) = small, Callisto(J), Ganymede(J) and Titan(S) = Medium, and Io(J), Rhea(S), Oberon(U) and Titania(U) = tiny for a total of 10 moons in the Sol system. You might add Iapetus (S) to the tiny list as well.
