- External Link: Unbelievably Strange Planets in Space
- External Link: HI. I'm have a question: What are the planet types in 2300 AD? Can others be added?

Additional classification of Planets (2017)
There is a finer division of the composition of planets. From GT: First In,p 57:
- A planet with a density of 1.3 to 3.0 is a silicate world, with a density 3.1 to 4.5 is a low-iron world, with density 4.6 to 6.0 is a medium-iron world, with a density 6.1 to 7.0 is a high-iron world, and with a density 7.1 and up is a metallic world.
- Values are in grams per cubic centimeter (gm/cc^3). Earth has a density of 5.5, a medium-iron world. Worlds consisting entirely of water (or ice) would be a silicate world.
- Icy bodies too small to be planets (i.e. have the gravity to be self-rounding) may have densities in the range of 0.8 to 1.3 range.
- From GT:First In, p 58:
- G = 0.0228 x K x D , where K is the density given above, and D is the diameter of the world in thousands of miles, and the result G is the gravity of the world in Gs.

Let's make a nonfunctional blank entry in the UWP and record it for future use. Great point.
- I didn't participate in the GURPS products like you, but I have read through all of them and love the work.
- I have already been deriving climate codes from the GURPS data.
- Let's brainstorm it sometime, please, and see what we can come up with.

Thomas, I like it. Well done.
- Please go over Jupiter if you get a chance.
