Creating UWPs for worlds in the SFU

[Sgt Major Al Beddow]

Hi all.

I am having some "fun" taking the SFU Planetary Designations (I.E. 'Class M")and the descriptions into the UWP. I'm having to go to dig deep and also hit a problem in that MGT doesn't have as wide a range of codes for some things as reported on the Traveller Wiki. I'm looking at expanding the UWP catagories that lack a full 16 definitions to better cover things like the planets in our solar system that are much larger than the SIZE chart goes to (Courtesy Wikipedia):

Jupiter: 139,822 km
Saturn: 116,464 km
Neptune: 49,244 km
Uranus: 50,724 km
Pluto: 2,376 km

I'm looking for input, suggestions, experience, etc on making this work right.

You would have to go through STANDARD PLANETARY CLASSES one by one to get the general codes for each.

I agree with Rivera here. That

Mancer, I think your message got truncated. Looks like you used a curly apostrophe and the system deletes/ignores everything from that point forward. You have to use "straight quotes" on this thing.

I've added in sizes from the Traveller wiki, but sticking with the single character code format of the UWP. Unfortunately the tables for MGT and T5/FFE don't line up (I have no idea why).

What do y'all think?

SIZE -- KM -- SURFACE GRAVITY (Gs) -- EXAMPLES

0 -- 1,000 -- 0.00 -- Asteroid, Orbital Complex
1 -- 1,600 -- 0.05 -- Triton
2 -- 3,200 -- 0.15 -- Luna, Europa
3 -- 4,800 -- 0.25 -- Mercury, Ganymede
4 -- 6,400 -- 0.35
5 -- 8,000 -- 0.45 -- Mars
6 -- 9,600 -- 0.70
7 -- 11,200 -- 0.90
8 -- 12,800 -- 1.00 -- Earth
9 -- 14,400 -- 1.25
A -- 16,000 -- 1.40
B -- 17,600 -- 1.90
C -- 19,200 -- 2.00
D --- 120,000 -- 2.50 -- Saturn
E --- 240,000 -- 3.00 -- Jupiter
F -- 1,000,000 -- 10.00
