Step One: Roll for planet size

Step Two: Determine Gas Giant Size Details

For small gas giants (SGG) roll 2d6 and consult the Small Gas Giant table. For large gas giants, (LGG), roll 3d6 and consult the Large Gas Giant table.

The Base Diameter is UWP X 1000. Roll 2D – 7 (giving a range from – 5 to + 5; reroll a “+ 5” result), multiply by 1000 (-5000 to +4000), and add to the Base Diameter. Roll a D10 for each digit after the UWP digit.
