Solar Systems

Guideline for information required to flesh out a star within a Solar System.



Name of Sun:

Solar System:

1st or 2nd Star in System / Binary Star system or not: Tatooine for example has a binary star system.

Orbiting Phenomena: Space stations, planets, Asteroid belts, etc.

Sequence Stage: Pre-Main Sequence, Post-Main Sequence, Main Sequence, Compact Stars

Type / Class:

  • There are seven types of main sequence stars in the galaxy;

“O” stars were blue and hot, and had a lifespan of less than one million years. There were approximately one hundred million habitable O stars in the galaxy.
“B” stars were white-blue and hot, and had a lifespan of ten million years. There were approximately one hundred million habitable B stars in the galaxy.
“A” stars were white and hot, and had a lifespan of four hundred million to two billion years. There were approximately one hundred million habitable A stars in the galaxy.
“F” stars were yellow-white and medium-temperature, and had a lifespan of four billion years. There were approximately one hundred million habitable F stars in the galaxy.
“G” stars were yellow and medium-temperature, and had a lifespan of ten billion years. There were approximately two billion habitable G stars in the galaxy.
“K” stars were orange and cool, and had a lifespan of sixty billion years. There were approximately 3.75 billion habitable K stars in the galaxy.
“M” stars were red and cool, and had a lifespan of approximately one hundred trillion years. They were also called red dwarfs. There were approximately seven hundred million habitable M stars in the galaxy.

With O stars being the biggest in the sequence, the size decreased gradually to the smallest M stars.

  • There are two types Pre-Main Sequence Stars;

Brown Dwarf; A brown dwarf was a star whose mass was too small to maintain hydrogen fusion reactions. Brown dwarfs were sometimes considered large gas giants.

Protostar; A protostar, also known as a proto-star, was an object that was formed by the slow collapse of a nebula that would eventually form a new star.

  • There are three types of Post-Main Sequence stars;

Red Giant; A red giant was a star that had progressed past the main sequence. It was smaller than a red supergiant.

Blue Giant; A blue giant was a massive star that had progressed past the main sequence.

Red Supergiant; A red supergiant was a supergiant star that had progressed past the main sequence. It was larger than a red giant.

  • There are four types of Compact Stars;

White Dwarf; A white dwarf was a small star formed at the end of a small to medium mass star’s evolution. These stars could no longer sustain nuclear fusion of hydrogen, and only gave off faint light from their residual heat.

Black Dwarf; A black dwarf was a rare compact star and one endpoint of stellar evolution. White dwarf stars that were once giant stars decayed into black dwarfs after burning all of their fuel and then cooling.

Neutron Stars; A neutron star was the stellar material that was left over from a supernova. Neutron stars had extremely strong gravity and could douse their star systems in lethal radiation. A rapidly rotating neutron star was known as a pulsar. The chemical element illerium was usually found in neutron stars.

Black Hole; A black hole was an astrophysical phenomenon with gravity of sufficient strength that it prevented even light from escaping. Black holes typically resulted from the supernova of extremely large stars (typically supergiants), which resulted in matter so heavy that they could push into the fabric of space, though some were thought to have been created in the initial moments of the formation of the universe.

Level of Activity: 1-5.

1 would be considered extremely less than normal activity, lack of Solar flares or even sunspots. Very dormant in nature. 3 would be nominal, normal functions and activity like our sun in life. Common sunspots, short lived solar flares, etc. 5 would be considered extremely dangerous with high activity. Solar flares that knock out technology temporarily or even permanently. Sunspots that covered vast amounts of surface that might cause problems for a planet in the system.

Prior / Next Cycle: What was the Star prior to its current form, and what will it be? Feel free to use the photo of Sun cycles to lay it out (Doesn’t need to be perfect).

Weather Effects:
Seasons Available, including duration and levels of dangers: Summer, Winter, Autumn, Spring, or maybe even make one up? Maybe the world is covered in ocean and during the Solstice season, transforms the surface of the world to its boiling point for 3 months straight.
Ecosystems of the World:

Ecosystem (Per Water/Land Mass)
Available Biomes per Water-Mass and or Landmass: Ocean, River, Beach, Forest, Jungle, Canyon, Dune, Cave, Snow, Desert, Mountain, Swamp, Grassland, Lake, Oasis, Volcano / Lava, Ravine, Highland, Plains, Grassland, Hills, Tundra, Steppes, Savanna.
Dangers: Cold, Hot, Suffocation, Lack of Water, Lack of Food, Low Visibility, Disease, Apex Predators, Dangerous Heights, Sinkholes, Blizzards, Heat Waves, Gravity / Fatigue.
Minimal Fauna: Critters, skittish little creatures like lizards, rabbits, bugs, that are around, mainly there for fluff and discovery
Major Fauna: named beasts, descript animals of all kinds.
Percentage of Major Fauna: Example (20% underground, 30% on land, 40% water, 10% airborne)
Minimal Flora: flowers, vines, fungi, etc that hold no large significance, mainly there for fluff and discovery
Major Fauna: named plants, descript plant life of all kind.
Percentage of Major Flora: Same as above.
Natural Resources: metal, plastic, wood, meat, bone, computer, etc.

Maps-Don’t worry about maps, I will create them myself. But feel free to add pictures of maps that may aid

There is a difference between the prominent and unfounded solar systems. 1. The prominent solar systems within the sector’s community, and therefore play a role one way or another at the surface. 2. The prominent systems are typically known, and are of use by anyone with a standard navicomputer. 3. The unfounded solar systems require delicate handling to find, and are therefore subject to being overlooked, products of myth or legend, or simply connected with other unfounded worlds, but are not prominent. Someone may stumble across an unfounded solar system and not realize it is uncharted, or maybe does not care. Someone else may desire to look further into the solar system just to find that all of the planets are barren, or takes a closer looks and never leaves. There are truly a thousand reasons as to why unfounded systems go for as long as they do, and primarily it has to do with how hard they are to find, needing the most precise precision to locate, or what is there to find…
