 ===== Planetary Classifications ===== ===== Planetary Classifications =====
  
-A classification is a type of anomaly that a planet might have, this can range from being a perfect pearl world where the climate is great for habitation, or could be one that makes habitation very difficult or even makes combat on that world likewise rather hard.  +A classification is a type of anomaly that a world might have, this can range from being a perfect pearl world where the climate is great for habitation, or, more likely, could make the world even more hostile than the depths of outer space. There are many different anomalies that a world can have, and the following list is not exhaustive. 
- +==== Desert World ==== 
-There are multiple different anomalies that a planet can have, and they are not just limited to the following list, but if you as a player and a creator have any suggestions - send them to [[user:kyle]] and he'll add them. +A desert planet resembles a standard garden world, except for having very little of one key resource: Water. The sky is clear, except during sandstorms, and life barely hangs on. These worlds tend to be smaller and have thinner atmospheres than most standard worlds. A world without an atmosphere is simply barren, not a desert world. 
- +==== Ice world ==== 
-==== Hollow Planet ==== +In most cases, ice worlds are literally made of ice, having formed far from their star; though not so far that their atmosphere has frozen on as well. Sometimes an ice world is an ocean world that is simply going through an ice age. 
- +==== Water World ==== 
-A hollow planet is a planet that has a network of tunnels that run throughout the outer, and even potentially the inner, crust of a planet. Although these tunnels can't be explained in how they were created, there can be speculation that it was either done naturally, a creature had done it, or even some long dead race. Whatever is the case though, these tunnels can be large enough for cities to be built inside and even for starships to pass through. +A water world is a terrestrial planet with so much water it has almost no (or even absolutely no) land area. In extreme cases, its oceans may be miles deep. These worlds may have life, but usually do not produce complex life, as life on land is considerably more challenging. The most likely worlds to have this condition (and to have the most extreme examples of it) are also the largest; worlds with dense helium atmospheres that for whatever reason were not able to gather enough material to become gas giants. Standard worlds may also less commonly have this condition. 
 +==== Hollow World ==== 
 +A hollow world is a world that has a network of tunnels that run throughout its crust. These tunnels may have no explanations, or there may be speculation that natural processes, native creatures, or long-dead colonists were responsible. Whatever their origins, these tunnels can be large enough for cities to be built inside, and even for starships to pass through. The protection of miles of rock can make these worlds difficult to bombard or invade.
 ==== Eden World ==== ==== Eden World ====
- +An Eden World is ideal for colonization, having a benign atmosphere and biosphere, and just the right balance of climate and temperature. Newly-discovered worlds of this type are coveted by many factions, and they are very rare!
-An Eden World is essentially a planet that has all of the right stats to be a world that is great for colonization.  +
 ==== Electromagnetic Storms ==== ==== Electromagnetic Storms ====
- +An anomaly that can be found on some worlds, EM storms can cause electronics to malfunction or burnt out, and can bring down starships, if they are not prepared. Even regular shield systems aren't effective in combating an EM storm. EM storms are particularly effective at interfering with sensor equipment. They are particularly common when the world in question is a major moon of a gas giant.
-An anomaly that can be found on some worlds, EM Storms are storms that mess around with electronic devices and can bring down starships if they don't have the proper shielding for their electronics, even regular shield systems aren't effective in combating an EM Storm.  +
- +
-EM Storms also make sensor scanning of a planet very difficult to do. +
- +
-==== Font ==== +
- +
-A font is a planet that is constantly shifting in terms of its land masses, this results in constant earthquakes each and every day of that planets life. This makes habitation excessively difficult. +
 ===== Planetary Special Conditions ====== ===== Planetary Special Conditions ======
-The following are planetary conditions that take the place of the specials tag when creating planets. These conditions are optional when creating planets, they are mainly there to add a bit more depth to a planet, such as bonuses, positives and negatives.  +The following are planetary conditions that take the place of the specials tag when creating planets. These conditions are optional when creating planets, they are mainly there to add a bit more depth to a planet. Particularly interesting planets are those that have both special advantages and flaws, for example, a world with a noxious atmosphere that also has a cavern system, encouraging residents to take shelter in pressurized habitats underground.
- +
-Ideally a planet can either have a positive or a negative, having both a positive AND a negative adds interesting elements. Examples being that the planet might have a Noxious Atmosphere, but may also have a Cavernous System, which means that while the surface is unfavorable for constructing buildings, the underground is not. +
- +
-Planets can also have both a ground and space based condition. +
 ==== Ground Based Conditions ==== ==== Ground Based Conditions ====
- 
 Ground Based Conditions refers to conditions that are found below its cloud cover.  Ground Based Conditions refers to conditions that are found below its cloud cover. 
- 
 === Dense Cloud Cover === === Dense Cloud Cover ===
- +Planets with dense atmospheres, especially large terrestrial planets (for gas giants, it goes without saying!), are often cloudy everywhere, all the time. This type of cloud cover makes it very difficult to see the surface with visual sensors, and can often obscure other sensors as well.  
-Dense Cloud Cover is the result of either a reoccurring storm on the planet or due to constant volcanic action. This type of cloud cover makes it very difficult to see the surface, rendering all form of sensor scanning technology useless due to the density of the clouds.  +=== Extreme Tectonic Activity === 
- +An unstable world that is largely unsuitable for the world is almost constantly shaking, forming mountains, or even liquefying. Engineers must take extraordinary measures to build anything lasting, and farming is mostly fruitless due to the broken terrain. Such worlds are also typically volcanically active, which offers something of a silver lining: They are likely to have valuable resource deposits exposed near the surface.
-=== Cavernous System === +
- +
-A system of caverns that reside under the planets surface, these caverns are very wide and dense in numbers, making them ideal for the construction of underground cities. This system also adds to the difficulty of sieging a planet, because most of the population might not even be located on the surface but rather underground, which adds another bonus of making it difficult to TAKE the planet as well.  +
- +
-=== Unstable Planetoid === +
- +
-An unstable planet that is not really suitable for much in terms of construction, the planet is in a constant - seemingly forever - state of shaking, this makes construction of buildings highly difficult; farming is useless due to the broken terrain. The only use such a planet has is that its ground is broken up to the point that rich sources of ore and other minerals are much more easily accessible.  +
 === Noxious Atmosphere === === Noxious Atmosphere ===
- 
 A Noxious atmosphere is one where the planet is not suitable by any lengths for colonization without the use of highly advanced life support systems, but this is depending on what makes up the atmosphere; some of these atmospheres might actually be dangerous to buildings.  A Noxious atmosphere is one where the planet is not suitable by any lengths for colonization without the use of highly advanced life support systems, but this is depending on what makes up the atmosphere; some of these atmospheres might actually be dangerous to buildings. 
  
Line 236: Line 210:
  
 While similar to moons, they differ in that they are not located in a stable orbit, these particular types of moons are dangerous because of how close they orbit their parent planet. Most planets that possess these types of moons may in fact not have a stable atmosphere or no atmosphere at all. While similar to moons, they differ in that they are not located in a stable orbit, these particular types of moons are dangerous because of how close they orbit their parent planet.

-As anyone can see from SARP's [[http://stararmy.com/setting/space/star_map_big.html|Star Map]], Star Army Galaxy has a vast number of different kinds of systems.  Like our own Milky way, this means that their are a vast number of different planets in Star Army.  To make both the Milky Way with over 497 planets and our Star Army Galaxy seem simpler, we can similar planets together in individual groups . This guide is also here to help with understanding the star system creation guide in particular by help people understand the vast number of choices they have when they use the Star System Calculator.\\+As seen on SARP's [[http://stararmy.com/setting/space/star_map_big.html|Star Map]], the Kikyo Sector has a wide variety of star systems, and those star systems have a wide variety of planets. Though every planet has its own unique properties, they can be grouped together into general types. This guide may also help to understand the star system creation guide, by describing the range of environments that might be generated using the Star System Calculator. 
 + 
 +The broadest way to classify planets is by their overall size. While size alone doesn't determine a planet's type, planets can be classified this way because their black body temperature, in conjunction with the planet's mass, determines the heaviest molecules the world can retain in its atmosphere. This means planets closer to their star, and orbiting brighter stars, might be more massive than colder planets that have been placed into a larger size category.
  
-Although it may seem strange, the broadest way to classify planet is actually by density and mass.  In fact, there are three main broad density-classified planetary groups-- Terrestrials,  Neptune-like, and Large Gas Giants.  Beyond this classification we can classify planets based on what their atmosphere, composition, or temperature.\\  +Since helium and hydrogen are the two most common elements in the universe, worlds that are large enough to retain helium usually, but not always, grow large enough to also retain hydrogen, and become gas giants. 'Standard' worlds are too small to retain helium, but still large enough to retain the all-essential water molecule. If they are in a star's habitable zone, they may have liquid-water oceans, a requirement for carbon-based life. Worlds somewhat smaller than this may still be able to retain dense nitrogen-based atmospheres, useful for exploration and terraforming. Smaller worlds never have significant atmosphere, and are only rarely of interest.
  
-//Note to self: need to remark about overlaping defintions and especially where ocean worlds fit.//+Gas giants themselves come in many sizes, from ten times the mass of a standard world to thousands of times that. Their moons are more likely to draw interest than the gas giant itself, though the radiation belts of gas giants can pose a significant hazard. The largest gas giants grow increasingly dense, eventually reaching the point where they ignite helium fusion in their cores, and become brown dwarf stars.
