The Solar System

[TKalbfus]

I’ve worked out a means of mapping the location of objects within the Solar System. The main problem with a Solar System campaign is that the planets and all other orbiting objects move. I’ve produced a chart to keep track of these objects as they move around the Sun. To start things off we need to establish each planet’s starting position, and for that I’ll roll d360

Object -degrees
Mercury 258/270
Venus 28
Earth 287
Mars 329/42
Vesta 60
Eugenia 253
Eunomia 286
Juno 100
Bamberga 305
Ceres 174
Pallas 208
Psyche 204
Interamnia 66
Patientia 192
Arethusa 250
Doris 189
Themis 303
Hygeia 75
Euphrosyne 338
Davida 48
Cybele 131
Sylvia 224

These are the positions of the planets and asteroids on week 0 of the campaign.
On Week 1 the following changes occur:

Object -degrees
Mercury 285.7/298.7
Venus 39.2
Earth 293.9
Mars 332.67/45.67
Vesta 63.48
Eugenia 256.05
Eunomia 288.94
Juno 102.89
Bamberga 307.87
Ceres 176.74
Pallas 210.74
Psyche 206.53
Interamnia 68.36
Patientia 194.36
Arethusa 252.35
Doris 191.3
Themis 305.28
Hygeia 77.26
Euphrosyne 340.25
Davida 50.23
Cybele 132.99
Sylvia 225.94

The number after the slash, in the case of Mars and Mercury, is the position of the object in it’s epicycle. Notice that the degree advance in the epicycle is by the same amount as in the orbit. This is all taken from the tables that follow:

Epicycle radii
Mercury 1.2 x 10^10m
Mars 2.14 x 10^10m

Mercury and Mars have elliptical orbits, each ellipse can be described in the following manner:
Each of the planets move in a counter clockwise direction along a circular track, in the case of Mercury and Mars, the location on the circular track is not where the planet is, instead the planet follows a clockwise smaller circle of the listed epicycle radius, with the planet making a complete circle around its epicycle at the same rate that the center of the circle makes a complete orbit around the Sun in a counter-clockwise direction. The degree advance is the same for the epicycle as it is for the larger orbit. The epicycle moves with the orbit and 0 degrees is always pointed in the direction of travel.

I’ve left a number of empty orbits, that I have none the less calculated the orbital velocity for and the degree advance, should the GM wish to place his own colonies or minor asteroids here Each of the above can be reduced to an algebraic equation that determines each objects position as a function of time. Earth’s position is determined by the following equation:

P = 287 + 2.9T where T is in weeks and P is in degrees around its orbit.

While that's pretty impressive, you do realise you can just download a program like Celestia and fastforward that to the date that you want, set the camera way above the solar system and turn the orbits on, and see how the planets and asteroids are arranged then...

A lot easier

. The good thing about using Celestia is that you could add your own planets and objects to the solar system or anywhere else and do the same thing for other systems too.

While that's pretty impressive, you do realise you can just download a program like Celestia and fastforward that to the date that you want, set the camera way above the solar system and turn the orbits on, and see how the planets and asteroids are arranged then...

A lot easier . The good thing about using Celestia is that you could add your own planets and objects to the solar system or anywhere else and do the same thing for other systems too.

Can Celestia do other star systems as well. If I just change the numbers, I can also do an imaginary system of planets here for Alpha Centauri. Also I can print this out. I can list the various objects and indicate which orbits their located in. Anyway, how could I post the results of Celestia here?

 

[Malenfant]

Yes, it can do other star systems (needs you to do a bit of work in the process, but then what doesn't).

As for printing out: not sure. It has a very versatile scripting function that could probably be used to MAKE it capable of printing out all the orientations etc. You can do a screen capture, certainly. And you can easily see where the objects are.

 

[TKalbfus]

Sounds like a good package, however I can't assume that everybody reading this will have Celestia, and I need some way of putting a Solar system down on paper for those who don't have it and for what I'm about to do next. Basically this is a Traveller setting without a Jump Drive or artificial gravity (gravitics). A Solar System with just little Ole Earth and a bunch of barren rocks is kind of boring. So to make it more interesting, we start the settin in the year 3000. I'll bet you can advance your Celestia clock and see were the planets are on January 1 of that year. I was wondering if you could output the results of that program, just give degrees if you could, to describe location of each planet in its orbit.

Each orbital track can be used as a place holder for each space settlement I place in the Solar System. For instance I could place some settlements in the orbit trace for 1.5 x 10^11m and list them as +34 degrees, and another one at +57 degrees, and a third at +203 degrees. These positions are all relative to the orbit trace, which is an imaginary ring in space that revolves around the Sun at its local orbital velocity. Everything on that ring moves at the same orbital velocity for game purpose, so its like the objects are sitting on a ring, and the ring itself is moving while all the objects on the ring hold their place on it. With all these rings in the Solar System and 360 degrees in a circle, I could place quite a lot of habitats on each ring without going into alot of detail to describe each individual orbit as they are all previously pre-established, you just place each object on one of the many orbital tracks already described. Since these are artifical objects, they don't hold to the relationship of natural planets called Bode's law, so each ring is placed at an interval 1 x 10^10m from each other unless their is a natural object such as a planet or major asteroid, in which case such an object gets its own orbit track. Major objects are always at 0 degrees on their respective tracks and all other objects are in +degrees relative to it. The track itself starts of rotated by some number of Solar System degrees, so a planet might be at some number, say 34 degrees and also be at 0 degrees relative to its own orbit track.

Now like planets, artificial space habitats have their own unique UWP. After the Spaceport digit, same as in Traveller, the first digit is of size in diameter. The scale for space habitats runs from 1 to 6 in stead of from 0 to 10 for planets. The 1 through 6 numbers also mean something different as the scale is exponetial rather than linear. Here is the artificial world size diameter ranges

Size - Range diameters
1 - 10m to 99m
2 - 100m to 999m
3 - 1000m to 9999m
4 - 10,000m to 99,999m
5 - 100,000m to 999,999m
6 - 1,000,000m to 9,999,999m

The second digit is length and it ranges from 0 to 10. The numbers here represent a multiple of the habitat's diameter. An 8 length on a habitat of size 3 (1000m) indicates it to be 8000m long. A 0 simply means that the length is less than its diameter, not a length of zero, this usually means the habitat is a wheel rather than a cylinder. A size 1 habitat could be a cylinder or a sphere. Any habitat over size 4 would most likely be a cylinder rather than a sphere as it center would contain vaccuum rather than air and would represent unlivable space.

The third digit is hydrographics. Hydrographics is usually kept to a maximum of 40% as an artificial habitat that is mostly ocean would be considered a potential waste of living space.

The other 3 digits are the same as Standard Traveller, but population is limited to habitat size in the following way.

Size - Pop
1 - roll 1d3-1
2 - roll 1d4-1
3 - roll 1d6
4 - roll 1d6+2
5 - roll 1d6+4
6 - roll 1d4+6

Determine all other digits as per Traveller UWP.

 

[Malenfant]

I think I can do that, but where do you want the degrees measured from? What's the reference line that is 0 degrees?

 

[TKalbfus]

The line that passes through the Earth when its the stroke of midnight at the end of December 31, 2004 and the beginning of January 1, 2005. That is the beginning of an Earth Year, and so seems a logical place to put 0 degrees on the ecliptic. Everytime there is a new year on Earth, the planet crosses 0 degrees.

 

[TKalbfus]

That's Greenwich Mean Time, of course at the Earth's Prime meridian, when the stroke of midnight occurs, to be exact. The year 2005 is an ideal time as its right after a leap year where the calendar resets itself. Though of course perhaps January 1, 2001 24:00 Greenich mean time would be a better date as its right after a century where 2000 was a leap year.

1900 AD was not a leap year as century years not divisible by 400 are not leap years according to the calendar rules. Lets go with the stroke of midnight at the beginning of the 3rd millenium instead. So draw a line between Earth on January 1, 2001 24:00 GMT and the center of the Sun and that would be marked as 0 degrees.

 

[aramis]

Tom, the logical "0" line for solar references should be something relatively fixed (calculation errors due to rounding could put you a degree or so off..) ; something readily measurable, and astronomically valid...

isn't the nominal reference the center of the galaxy? so line sol-MWSMBH defines 0 line, along a plane defining a o-ray at 90deg to the galactic eccliptic, defining the line for the local eccliptic...

and that, coincidentally, matches traveller measurements...

Here's what I put together for a Solar System Campain set sometime in the 22nd century. Enjoy!

Seeing as how ALL orbits are elipses, and that they can have any orientation at all in respect to the galactic center, why not allow for local coordinates (in system) to be based on something in the system?

Probably your best bet for something consistent across any star system is to use the closest natural object to the star (though we can fiat to the mainworld or whatever we want) as the basis for our measurements? The perihelion point of that object is your 0 position, its orbit defines the ecliptic in the system, and so on.

As it is, the Solar system already has Earth chosen as its basis for everything. It is odd that our year doesn't start at Perihelion, though. If we weren't here, and discovered this system, we might instead choose Mercury to base the 0 point on, or if we went to Alpha Centauri, we might choose the perihelion of ACb, since that's going to be an important event.

in the spinward marches deneb will be very prominent. it could easily serve as a semi-permanent reference point for any local system.

I actually got a coordinate system from the Space Encyclopedia from National Geographic. They have a Map of the Solar System with all the Planets positions as of January 4 2004, with the degrees marked, so that's not a problem. I haven't decided what year to set it in yet. Its set in the 22nd century. The largest space colony size is a double cylinder with each cylinder 20 km in diameter and 100 km long. This is your typical Island Three Configuration. The Alpha Cylinder has a population of 700,000, and the Beta Cylinder has a population of 2,500 and is the Municiple park. Each cylinder makes a complete rotation in 200.6688 seconds to create 1 g of simulated gravity force on the inner surface, it is a captive colony government, with a law level of 6 and a tech level of 9, and a Class A starport for the Alpha Cylinder and a class C Starport for the Beta Park Cylinder.

Here is a sample list of equipment for the Solar System Campaign. The Unit of currency is the US dollar, and as you can see, it doesn't buy what it used to. Jump-1 Drive has only recently been discovered, there are no used starships available. The three models below are the only ones manufactured, although other starships can be built in shipyards with spare parts. The Planet Prometheus in the Alpha Centauri system is in the early stages of settlement. Artificial gravity, and grav plates exist only in laboratories and are so far non-economical to mass produce. Starships and smallships experience zero-gravity when they are not under acceleration. All of the Space Colonies, utilize rotation to simulate gravity.
