| How would planets such as Kepler-10c rank? It is around the size of Neptune, but, is denser than Earth, thus meaning it might be rocky.

| SpaceEngineer:
Certainly, nobody denies that ice giants would become gas giants if they were more massive and there was more gas available -- those are the conditions for creating a gas giant. The initial formation phase you're describing is also true for all planets (with possible exception of gas giants formed through a disk-instability scenario). But we certainly do not say that Earth is a gas dwarf? 
The point I'm getting at is the divergence of evolution beyond that initial core-accretion. Formation of gaseous envelopes requires availability of large amounts of gas in the nebular environment, and sufficient mass to retain it. Failure of these conditions leaves us with rocky planets near the sun, and ice giants beyond the snow line. Ultimately the evolutionary path is determined by the properties of the disk where the planet is forming -- density, composition, and temperature vary with solar distance. Evolution can be further complicated by planetary migration, resonances and all sorts of chaos.

It lies (roughly) here on this diagram and is probably a rocky planet with some water content. Not liquid water of course, but ice under high pressure. According to SpaceEngineer's planet classes it could be called a warm (hot?) superterran.

| Will those alternative classification sets be user selectable or will there be just one set chosen for the release and they were presented here for critique?

| 0.972 will have old planet classification (ie not changed).

| I have found a world that got me thinking about space engines planet definitions. There are clear definitions for terrestrial and gas giant world but no classification for the grey area. I submit to Space Engineer that you consider this for patching, I found a world that I think should be a gas Sub-Giant. It has 600atm at the surface but the thing is it's an oceanic so the pressure at the bottom of the ocean as at gas giant levels.
What I'm basically asking for here is a "what if" when the planet is generated like ESI. If it matches certain criteria then it becomes a Sub-Giant.
Images and location of the planet:
RS 0-7-1760765-842-63-6-114409-3748 A8

| NASA Discovered a new type of planet called a gas dwarf. Look it up.

| I think your classification is great. Don't change it. Maybe only add some data:
Atmosphere composition? (%s of top 3 gasses? e.g. water, oxygen, ammonia, iron, methane, CO2, etc etc.)
Surface composition? (% rock, % metal, % heavy metal, % water/ice)
Calculate colour of surface and atmosphere from data.

| Quote yaqdark ( ) Surface composition?
And maybe, if you change colors according to surface composition, then maybe generate how much Iron there is, so we might find a few planets like Mars?

I have actually found a lot of mars-like planets.

| Is this all the planet classifications or are there more that haven't been added yet?

If you want a list of most classes...check out my thread xD

| We need Carbon planets and Cthonian planets. Gas dwarfs and rouges are also needed.

| Quote steeljaw354 ( ) We need Carbon planets and Cthonian planets. Gas dwarfs and rouges are also needed.
They will fit into SE classification.
Carbon - desert or titan.
Cthonian - gas giant, ice giant, oceania or desert, depending on evaporation progress.
Gas dwarf - lightweight ice giant or heavy desert with thick atmosphere.
Rouge planet - not need a separate class. Classification in SE is based on mass and temperature, so it could be any "frozen" class.

| What about Y9 dwarfs what would they look like? Frozen terras? Terras with high pressure and a certain compound in water that would prevent water from freezing.
