+ | ===== Planetary Classifications ===== | ||
+ | |||
+ | 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 ==== | ||
+ | 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 ==== | ||
+ | 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 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, | ||
+ | ==== Eden World ==== | ||
+ | An Eden World is ideal 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. | ||
+ | ===== 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. 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. | ||
+ | ==== Ground Based Conditions ==== | ||
+ | Ground Based Conditions refers to conditions that are found below its cloud cover. | ||
+ | === Dense Cloud Cover === | ||
+ | Planets with dense atmospheres, | ||
+ | === 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. | ||
+ | === 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. | ||
+ | |||
+ | === Dense Flora === | ||
+ | |||
+ | A planet that is covered in dense flora makes for a good planet to house agricultural industries, but also makes life difficult on invading forces. | ||
+ | |||
+ | === Atmospheric Instability === | ||
+ | |||
+ | Atmospheric Instability refers to a planet whose atmosphere is slowly being ' | ||
+ | |||
+ | === Volcanically Active === | ||
+ | |||
+ | This type of planet is highly active in terms of volcanic activity, earthquakes are also common-place and the land is usually covered in molten seas and lakes. The average temperature may be to high for people to explore the planet without specialized equipment and even then setting up buildings is next to impossible. A phenomenon known as ' | ||
+ | |||
+ | === Lava Rain === | ||
+ | |||
+ | Lava Rain is essentially lava that has been spewed into the air at such high velocities that it comes back down to the planet in the form of rain, usually resembling very thin threads that are capable of puncturing bodysuits and most lightly armored individuals, | ||
+ | |||
+ | === Ancient Ruins === | ||
+ | |||
+ | These ancient ruins are evidence of a once long dead civilization, | ||
+ | ==== Orbital Conditions ==== | ||
+ | |||
+ | Like the ground based conditions, this one relates to what might be orbiting a planet. | ||
+ | |||
+ | === Dense Planetary Rings === | ||
+ | |||
+ | Dense Planetary Rings are a boon to mining corporations, | ||
+ | |||
+ | === Derelict Starship === | ||
+ | |||
+ | Derelict Starships can either be a boon or a hindrance depending on what is contained within; such ships can either be big or small, wide or narrow. | ||
+ | |||
+ | === Derelict Station === | ||
+ | |||
+ | Similar to a derelict starship, derelict stations can pose both a positive or a negative depending on what is found within. Some of these stations could be in a decaying orbit, which means they would eventually crash onto the planet and depending on their size - they could easily cause considerable damage upon impact. | ||
+ | |||
+ | === Moons === | ||
+ | |||
+ | Self-exclamatory. | ||
+ | |||
+ | === Close Orbital Planetoids === | ||
+ | |||
+ | 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. | ||
+ | ====== Star Army Guide to Types of Planets ====== | ||
+ | | :!: **The following article is currently NOT APPROVED for in-character usage.** | | ||
+ | As seen on SARP's [[http:// | ||
+ | |||
+ | The broadest way to classify planets is by their overall size. While size alone doesn' | ||
+ | |||
+ | 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. ' | ||
+ | |||
+ | 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.\\ | ||
+ | |||
+ | === Units === | ||
+ | Before we can really talk in detail about exoplanets we need to have an understanding of units we use for Density, Temperature, | ||
+ | The Average Density of a Planet is of course roughly a planets mass divided by the Approximate Volume it would have it it was a perfect sphere. | ||
+ | The Average Surface Temperature of a planet is measured in either degrees Celsius or degrees Kelvin. | ||
+ | The Planetary Mass like all masses is first and foremost measured in units of kilograms. | ||
+ | The table below highlights conversions between various mass units | ||
+ | ^ Mass Unit ^ Symbol ^ Conversion to kg ^ Conversion to ME ^ Conversion to MJ ^ Conversion to Sol^ | ||
+ | | 1 Earth Mass | 1 ME | 5.98 E24 kg | 1 ME | 1/(317.83) MJ | 1/ | ||
+ | | 1 Jupiter Mass | 1 MJ | 1.8986 E27 kg | 317.83 ME | 1 MJ | 1/(1048.14) Sol | | ||
+ | | 1 Solar Mass | 1 Sol | 1.99 E30 kg | 332,775.92 ME | 1,048.14 MJ | 1 Sol | | ||

+ | ====== Non-standard Planet Types ====== | ||
+ | Some planets do not fit into the general pattern, resulting from extraordinary cosmic events or works of artifice. | ||
+ | ==== Artificial Planets ==== | ||
+ | | ||
+ | ==== Pulsar Planets ==== | ||
+ | | ||
+ | | ||
+ | ==== Rogue Planet ==== | ||
+ | -A rogue planet is a planet without a star, and as such they tend to be very, very, very cold, with no source of heat other than gravitational contraction and radioactive decay. They are difficult to detect, often uncharted, and can make good hideouts for those lucky enough to find them. Rogue planets form around stars, but can be ejected by any number of means, most often a close encounter with an erratically orbiting gas giant, or another star. | ||

+ | |||
+ | |||
- | 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, | ||
- | 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 it's land masses, this results in constant earthquakes each and every day of that planets life. This makes habitation excessively difficult. |
