Saturn

Gas Giant Saturn is the second largest planet in the Solar System after Jupiter.

## Planet Overview

### Atmosphere Composition

Hydrogen-Helium with some amounts of Ammonia & Methane

## Colonial Info

### Controlled By

The Federation, Autonomous Government of Uranus

### Main Economy

Mining, Heavy Industries, Tourism

**Location:** Milky Way Galaxy/Local Cavity/Solar System

**World Category:** Hydrogen-Helium Gas Giant

**Saturn** is the sixth planet from Sol and the second-largest in the Solar System, after Jupiter. It is a hydrogen-helium gas giant with an average radius of about nine times that of Earth. Saturn is named after the Roman god of wealth and agriculture. The planet's most famous feature is its prominent ring system, which is composed mostly of ice particles, with a smaller amount of rocky debris and dust. 89 moons are known to orbit Saturn, of which 52 are officially named. Titan, Saturn's largest moon, and the second-largest in the Solar System, is larger than the planet Mercury, and is an important industrial world.

Saturn has been a source of Helium-3 fuel for nuclear fusion and terraformation machines since 2129 and its moon Titan is mined for hydrocarbons since 2092. Titan is also being used as a hostile alien environment for military trainings by the Federation.

## Planetary Properties

### Physical Characteristics

Saturn is a gas giant composed predominantly of hydrogen and helium. It lacks a definite surface, though it may have a solid core. Saturn is the only planet of the Solar System that is less dense than water—about 30% less. Jupiter has 318 times Earth's mass, and Saturn is 95 times Earth's mass. Together, Jupiter and Saturn hold 92% of the total planetary mass in the Solar System.

### Natural Satellites

Saturn has 89 known moons, 53 of which have formal names. In addition, there is dozens to hundreds of moonlets with diameters of 40–500 meters in Saturn's rings, which are not considered to be true moons. Titan, the largest moon, comprises more than 90% of the mass in orbit around Saturn, including the rings. Saturn's second-largest moon, Rhea, may have a tenuous ring system of its own, along with a tenuous atmosphere.

Many of the other moons are small: 41 are less than 10 km in diameter and another 14 between 10 and 50 km in diameter. Traditionally, most of Saturn's moons have been named after Titans of Greek mythology. Titan is the only satellite in the Solar System with a major atmosphere.

### Planetary Rings

* *Main Article: **Titanides***

Saturn is probably best known for the system of planetary rings that makes it visually unique. The rings extend from 6,630 to 120,700 kilometers (4,120 to 75,000 mi) outward from Saturn's equator and average approximately 20 meters (66 ft.) in thickness. They are composed mainly of water ice. While the other gas giants also have ring systems, Saturn's is the largest and most visible.

It was proven in 2160 that the rings are remnants of a destroyed moon of Saturn.

## Colonization

### Early History

Saturn's Moon Titan was a colonial target since 2050s after the successful colonization of Mars, but its distance to Earth and Mars postponed the colonization to 2080s. Humanity arrived on Titan as part of a scientific landing, but actual colonization planning began in 2070 when the new nuclear fusion powered starships became operational and therefor reducing the time and effort needed to reach Titan. A massive effort were put into analyzing Titan to prepare for the eventual colonization. in 2089, China was the first country to arrive on Titan to colonize it, and the first domed colony was established shortly after with pre-built modules. In 2092, Hydrocarbon mining began on Titan as well, making it a beginning for Titan to become an important industrial hub in the next few centuries.

### EUSI Era

Saturn sector was never a point of attention to Earth until the fall of Jupiter in 2132. After the end of the Colonial War, Earth lost its access to Jupiter Helium-3 mining, and therefor turned its attention to Saturn. Heavy investment were put into Helium-3 mining operation to see to the needs of Earth, and in a few decades, the population of Saturn sector increased from less than 5 million people (only on Titan), to more than 30 million in just a few decades.

### Solar System Interplanetary War

Saturn had become the most important sector to humanity in the dawn of the 23rd century. In 2204, a major interplanetary war broke out between EUSI and the Imperium with the Invasion of Earth from Mars. Saturn was a major part of this war. Imperium invaded this sector in late 2205, with the goal to get access to Titan resources and industries, cutting of Earth's most important Helium-3 supplies, and making its own Jupiter sector safe from any strike from EUSI. Imperium installed a government on Titan to administrate this sector during the war, but this new regime revolted against the Imperium and dealt a major blow to its war efforts.

The war in this sector finally ended when the combined fleet of Authority of Titan and Autonomous Government of Uranus destroyed the last remnants of the Imperium in 2226, 2 years after the fall of the Imperium .
