03/14/21:

Fixed a couple of minor typos.

Increased the # of objects (planets, moons, asteroids, etc) in:
Deneb (Was 13, now 26)
Vultaumar (Was 10, now 20)
Yuhtaan (Was 14, now 25)
Fen Habbanis (Was 10, now 20)
Irass (Was 13, now 25)

02/21/21:

More gas planets (spawn chance up to 30 from 6)
More frozen planets (spawn change up to 18 from 10)
Fewer tomb worlds (spawn change down to 0.1 from 0.15)
Fewer gaia worlds (spawn change down to 0.02 from 0.05)

Habitable zone shortened to 13 to 21, from 5 to 20, effectively reducing the number of habitable worlds to 1/3rd of previous numbers.
Habitable world spawn variety better balanced. (Ex: Dry planets no longer outnumber Cold planets 5:1)

12/4/20 Update:

-Gas giants (Hot Neptunes) can now spawn in the inner & habitable zones.

-Added:
Tau Ceti
Kepler 296
Kepler 62
Kepler 186

-Made some minor changed to existing systems (planet types, size, etc)

11/23/20:

Resized black holes, neutron stars, & pulsars to size 4, from size 3.

Solar systems now generate with:
Inner Zone (1-2) planets with no moons,
Habitable Zone (1-2) planets with (0-1) moons each,
Inner Giants (1-2) gas giants with (0-5) moons each,
Outer Giants (1-2) gas giants with (0-4) moons each,
Outer Zone (1-2) planets with (0-1) moons each.

This results in a possible range of 5-10 planets, 0-22 moons per system.
(Vanilla typically had a possible range of 2-10 planets, 0-10 moons per system.)

Updated all solar system initializers.

Resized a few overlooked stars & planets

11/22/20:

-Adjusted distance scale to .0606 AU = 1 distance
-Habitable Zone planets can have 1 moon maximum
-Updated 7 Sol System textures (mostly color correction) (Mimas, Proteus, Ceres, Tethys, Dione, Charon)
-Reduced habitable zone to 5 to 20 distance, from 3 to 20
-Reduced habitable_spawn_odds to 0.1 from 0.5

11/20/20:

-Gas giants now have a maximum of 5 moons
-Moons now orbit 1 or 2 distance, down from 1 to 3
-Habitable zone has been greatly reduced (from 5 to 60, 55 total - to 3 to 20, 17 total)
-Updated Empire starting systems
-Updated Misc systems
-Adjusted planet zoom levels
-Exported Planetary Diversity compatibility to a submod

Removed an extra } in special_systems_initializers, a leftover typo from Vanilla.

Thanks to Diettinger for spotting it!
