Planet Body (Size and Mass); D10
! Roll
! Meaning: Rocky Planet
|-
! 1
|'''Small, Light:''' The already-small world is low in metals, and so has even lower mass than it appears.
|-
! 2-3
|'''Small:''' Too small for strong gravity or abundant resources. Subtract 5 from the result of its Gravity roll.
|-
! 4
|'''Small, Dense:''' As ''Small'' but with higher gravity and more mineral resources available.
|-
! 5-7
|'''Large:''' Worlds of this size can range across a vast spectrum of possible types.
|-
! 8 
|'''Large, Dense:''' As ''Large'' but with higher gravity and more mineral resources available.
|-
! style="white-space: nowrap;" | 9-10
|'''Vast:''' Huge and voluminous, worlds of this type strain the upper edges of the possible size for a single world. Such planets tend to be of middling density, as they are already more massive than is common. Add 5 to the result of its Gravity roll.
|-
! Roll
! Meaning: Gas Giant
|-
! 1-2
|'''Gas Dwarf:''' Considerably more massive than most rocky planets, but small for its kind. Subtract 5 from the result of its Gravity roll.
|-
! 3-8
|'''Gas Giant:''' Vastly more massive than any rocky world, with accordingly powerful gravity.
|-
! style="white-space: nowrap;" |'''9-10'''
|'''Gas Titan:''' The titans among gas giants are larger than some small stars, and may even be 'Brown Dwarfs', arguably closer to being stars than planets (the difference is that a true star can maintain fusion reactions, Brown Dwarfs can't). Roll another ''D10''; on an ''8+'' this is a Brown Dwarf; its Gravity roll is an automatic ''10'' and its moons are generated as if they were one Solar Zone closer to their star. On a ''1-7'' it is an 'ordinary' titan and merely adds 3 to its Gravity roll.

'''Dense''': A Dense planet adds 5 to the result of its Gravity roll. Increase the Abundance of any Mineral Resources it holds by 10.

'''Light''': Subtract 2 from the result of its Gravity roll, and halve the Abundance of any Mineral Resources it holds.

!'''Orbital Feature Rolls'''
|-
! style="white-space: nowrap;" | -6-2
|'''Low Gravity:''' Subtract 10 from its rolls for Orbital Features and subtract 2 from its roll for Atmospheric Presence. Maneuvering on this world may be difficult for those not accustomed to it.
|D2
|-
! 3-8
|'''Normal Gravity:''' Approximately the same gravity as Terra's standard 1 G. No effects.
|2D3-1
|-
! 9+
|'''High Gravity:''' Add 10 to this planet's rolls for Orbital Features and add 1 to its roll for Atmospheric Presence.

|'''Weak:''' Weak gravity for a gas giant, though still stronger than almost all rocky planets. Subtract 5 from its rolls for Orbital Features.
|D6
|-
! 3-6
|'''Strong:''' Enormous gravity field, normal for its type. No effects.
|D6+D3
|-
! 7-9
|'''Powerful:''' Objects well beyond its immediate surroundings feel its pull. Add 5 to its rolls for Orbital Features.
|2D6
|-
! 10+
|'''Titanic:''' Even the system's star is affected by this world's gravity. Add 15 to this planet's rolls for Orbital Features.
