Refer to: <a href="/node/1001">Planet / System Generator - d100 Project Outline</a>.<br /><br />Here are the categories I think pertinent. This will be a simplified system for determining each type of planet without having to roll each and every detail. First you roll or choose the type of planet from the Orbital Body Type Table. Then you roll just a few stats: Size, Gravity, Water, Atmosphere, and Satellites. For Satellites you again roll on the Orbital Body Type Table and then roll for Size, Gravity, and Atmosphere. The Atmosphere Table receives a Solar Radiation modifier from the Star Table, a Gravitational modifier from the Gravity Table, and a Humidity modifier from the Water stat on the Size table. Gravity receives a Gravitational Modifier from the Star (or Gravity) Table and a Mass modifier from the Size Table. These modifiers apply to specific stats on the tables. Gravity and Atmosphere also provide direct modifiers to character stats and vehicles on that planet. You can either roll on the tables or you can select the options to match your vision of the planet you have in mind.<br /><br /><b>SYSTEM TABLES</b><br /><br /><b>Star Type</b><br />Blue Dwarf<br />Yellow Dwarf<br />Red Dwarf<br />Blue Giant<br />Yellow Giant<br />Red Giant<br />White Dwarf<br />=Solar Radiation modifier<br />=Gravitational Modifier<br /><br /><b>Number of Planets</b><br />1d10 +1<br /><br /><b>Orbital Body Type</b><br />Molten<br />Rock<br />Inhabitable<br />Jovian (Gas Giant)<br />Ice<br />Asteroid Belt<br /><br /><b>Comet Types (roll 1d10 for number of comets)</b><br />(More research needed)<br /><hr size="2" width="100%" /><br /><b>PLANET TABLES</b><br /><br /><b>Size<br /></b>Size<br />Diameter/circumfrance<br />Surface Area<br />Core<br />Mantle<br />Crust<br />% Surface Water (=Humidity modifier)<br />=Mass modifier<br /><br /><b>Gravity</b><br />(apply Mass modifier and Gravitational modifier)<br />Orbital Distance<br />Orbital Velocity<br />Rotation<br />Tilt<br />Gravity<br />=Gravitational modifier (to ships, moons, and atmosphere)<br /><br /><b>Atmosphere</b><br />(apply Solar Radiation modifier, Gravitaional modifier, and Humidity modifier)<br />Air Pressure<br />Avg Humidity<br />Atmospheric Compositition<br />Min Polar Temperature<br />Avg Inhabitable Zone Temperature<br />Max Equitorial Temperature<br /><br /><b>Satellites</b><br />Number of Moons (roll 1d10 -2)<br />Moons (Roll on Orbital Body Type)<br />Orbital Debris (Rings)<br /><br />*An ice planet does not mean a frigid wasteland, but means near absolute zero. Only ice planets can orbit ice planets and ice planets can only be found on the outer edge of the solar system.<br /><br />This can help provide the science and realism for games and articles while retaining playability as well as the Star Frontiers feel.
