Overview

A procedural framework for generating planets across Maf's setting, covering broad category, region distribution, and a standard data template ("Header") used to generate individual worlds.

Planet Categories

• Gas planets — must be sited no less than 4x the outer edge of a star's habitable zone
• Rocky/terrestrial planets — subdivided into: Planets, Dwarf Planets, Asteroid Belts, and Double Planets (two bodies within 15% of each other's size, orbiting a shared center of gravity — deliberately made very rare)

The 10 Regions & Distribution

Confirms and refines the Snickers Galaxy/Milky Way relationship: Snickers is confirmed to be about 80% the size of the Milky Way. Ten regions where planets may be generated, with a distribution schedule:

This confirms Maf/Snickers-based space dominates generated content (66% combined for Snickers + Snickers Remote), consistent with the setting's focus, while still leaving room for the wider multi-galaxy scope established elsewhere (see Maf — Present Day).

Star Types

Follow scientifically accurate main-sequence classification (color, size, age, luminosity) — randomized per planet but constrained to real astrophysical plausibility.

Standard Planet Data Header (template)

Star Name, Star Type, Star Diameter, Star Age, Luminosity, Location, Number of Planets and Asteroid Belts; then per-planet: Planet Name (star name + Roman numeral by distance from star), Planet Diameter, Planet Type, Gravity (Earth G's), Orbital Distance, Axial Tilt, Hydrosphere, Average Temperature, Atmosphere Composition/Height/Density, Inhabited (Yes/No), Intelligent Life, Number of Moons, Geostationary Orbit, Escape Velocity, Rotational Period, Revolution, and Notes (unique attributes + life status).

Example Generated Planets

• Zephyrion I — G-type star, Confluence Region, terrestrial, 47% hydrosphere, uninhabited
• Zephyrion I — G-type Main Sequence star, Confluence Region; terrestrial, uninhabited. Star diameter 684,000 mi, age 4 billion years, luminosity 1.2x Sol. Planet diameter 7,950 mi, gravity 0.85G, orbital distance 83.7M mi, axial tilt 23.5°, 47% water coverage, avg. temp 72°F, atmosphere 75% nitrogen/23% oxygen/2% trace, 2 moons, rotation 24.5 hrs, year 356 days. Notes: lush, varied landscape with rolling plains and expansive oceans; mild seasons make it attractive for scientific research and modest colonization, despite no intelligent life discovered.
• Vega Prime I — A-type Main Sequence star, Milky Way, inhabited with intelligent life. Star diameter 2.1M mi, age 2.2 billion years, luminosity 9x Sol. Planet diameter 10,400 mi, gravity 1.15G, orbital distance 63.9M mi, axial tilt 17.2°, 58% water coverage, avg. temp 88°F, atmosphere 80% oxygen/18% nitrogen/2% trace, 2 moons, rotation 21.6 hrs, year 288 days. Notes: home to a thriving civilization that has harnessed the planet's resources responsibly, creating a harmonious balance between technological progress and ecological preservation.
• Pulsarion I — neutron star (pulsar) system, Milky Way; corrected during generation to a single unusual captured planet (see below)

✅ Self-Corrected Error (not an open issue)

An early draft generated a planet ("Pulsarion II") orbiting a 50,000-year-old star — the creator caught this as scientifically implausible (planetary systems take millions to billions of years to form) and the two of them corrected it together within the same session, settling on a single unusual captured planet (Pulsarion I) as the only planet in that young system. This was already resolved in the original conversation, not a pending contradiction.

Pulsarion I full stat block: Neutron star (pulsar), diameter 12 miles, age 50,000 years, highly variable luminosity due to pulsar activity, located Milky Way. Planet diameter 6,200 mi, gravity 0.72G, highly elliptical orbit (captured from another star system), axial tilt 9.5°, limited hydrosphere (frozen water at poles only), avg. temp -90°F, thin atmosphere (remnants of its original), 1 moon, rotation 28.1 hrs, highly irregular year length due to its captured orbit. Notes: a captured planet with a complex history — its irregular, highly elliptical orbit suggests capture from another star system; its frozen polar regions and thin atmosphere present unique exploration challenges.
