DETERMINE PLANETARY SYSTEM

These are planets immediately detectable upon jump and included in most Information about the system. There may be more Planetary systems information but this is what is available upon initial arrival in the system. The referee can choose to limit or reduce the amount of information and its accuracy to those outside the solar system. For the purposes of clarity, we will refer to each World or Planet or Disk as a “Body”. For O, B, A systems, roll 11D6-11 for Circumstellar Disks and ignore other columns.

Class	Color	Planetary System Mass Modifier
O	Blue	Disks only
B	deep blue white	Disks only
A	Blue white	Disks only
F	White	Adv+2
G	Yellowish white	Adv+1
K	Pale yellow orange	None
M	light orange red	Dis+1

Planetary Systems Table

Make a roll for each column to get the number of each type of Body in the system. The roll for the mass of each body on this table and multiply it according to a roll on the Planetary Mass Modifier Table. Note that some types of stars give Adv or Dis to the Mass roll as per the Star Type Mass Modifier Table above.

DETERMINE PLANETARY POSITIONS

STEP 1: Check the Zone Information of the Solar System (see Zone Formula Table, or Zone Enumerated Table) and note the position of the main world and any companion stars.

STEP 2: Roll dice as noted on each column on the Planetary Systems Table above to get the number of each type of Body in the system. For each of these, roll 2D6 on the Planetary Systems Table to determine its mass, incorporating bonuses, then (optionally) roll on the Planetary Mass Modifier Table.

The results represent known worlds in the system and not necessarily all worlds in the system.

O, B, and A stars only have Disks

Planetary System Qualities and Position Table (Roll 1D6 in case there are multiple possible Zones)

WORLD	INFERNAL ZONE	HOT ZONE	CONS. HABITABLE ZONE	OPT. HABITABLE ZONE	OUTER SOLAR SYSTEM
Class I Gas World: Ammonia Clouds
Class II Gas World: Water Clouds		4 to 6	1 to 3
Class III Gas World: Cloudless
Class IV Gas World: Alkali Metals
Class V Gas World: Silicate Clouds
Ice Worlds
Dwarf Planets
Carbonaceous Lesser Earth		4 to 6	1 to 3
Silicaceous Lesser Earth		2	5 to 6	3 to 4	1
Metallic Lesser Earth	1	3	5 to 6	4	2
Other Lesser Earth	1	3	5 to 6	4	2

STEP 3: Use the Planetary System Qualities and Position Table above to determine what zone each Dwarf Planet, Terrestrial World, Ice World and Gas World is in and the World Position Table below to get the exact distance. In case a world ends up in the same orbit as another world (or a star), just distribute the positions evenly between that orbit and [that orbit x 1.5]. If necessary, assume that the orbits are skewed such that there are no collisions. Note that Planets and Lesser Earths can occupy the same position as a Circumstellar Disk.

Main World Position Table

Roll 1d6 and get distance as per formula below

Zones	Main World Position
Infernal Zone	√L☉ (0.067AU x 1D6)
Hot Zone	√L☉ ((0.067AU x 1D6) +0.4AU)
Conservative Habitable Zone	√L☉ ((0.067AU x 1D6) +0.7AU)
Cold Zone	√L☉ ((0.61AU x 1D6) +1.2AU)
Outer Solar System	√L☉ ((1D6)2 +4.85AU)

STEP 4: To determine the Zone that Circumstellar Disks are in, use the Disk Zones Table below. Then roll for the distance on the World Position Table above. In case a circumstellar disk ends up in the same orbit as a circumstellar disk or a star, just distribute the positions evenly between that orbit and [that orbit x 1.5].

Disks Zone Table

2D6	Disk Zones
2-	Infernal Zone
3	Hot Zone
4	Conservative Habitable Zone
5	Cold Zone
6+	Outer Solar System

STEP 5: If desired, one can generate asteroids within each disk by rolling 2D6 on the Planetoid-Asteroid Mass Table on the next page, adding the Planetoid-Asteroid Modifier from the Planetoid Asteroid Modifier Table below to that roll. If even more precision is required, one can further multiply the size by the result of a D66 roll in the PA Mass Multiplier Table. When determining the size of multiple asteroids in a Disk, succeeding Disks should have a cumulative -2 penalty (-2 for Asteroid 2, -4 for Asteroid 3, and so on…). For more detailed Asteroids, roll on the Asteroid Type Table.

Planetoid-Asteroid Modifier Table

Circumstellar Disks	Planetoid-Asteroid Modifier

1 CM	+23

This table provides a modifier when rolling on the Planetoid-Asteroid Mass Table below.

12	Other	Adv+3

Planetoid-Asteroid Mass Table

For a Significant Planetoid-Asteroid, roll 2D6 plus the Planetoid-Asteroid Modifier (based on the mass of the Circumstellar Disk’s Mass. For multiple Asteroids, apply a cumulative -2 Penalty to every succeeding roll (-2 for Asteroid 2, -4 for Asteroid 3, and so on…), until the Modifier is 0.
