Système Sol

Humanity’s homeworld and namesake of the United Empire of Earth. It is the center of the UEE political machine and a focal point in the Empire’s commerce and culture. Centuries of habitation have stripped the planet of its natural resources resulting in a heavy dependence on imports for the billions that live here.

This gas giant is the largest planet in the Sol System.

Article

A prosperous and populous planet, Mars was the Empire’s first successfully terraformed planet. The process was marred by what is today known as the Mars Tragedy when a terraforming disaster killed 4,876 people in 2125.

Article

Due to an orbital eccentricity, this small planet experiences the greatest temperature variations of any planet in the system.

Article

An ice giant whose differential rotation contributes to it having the strongest winds in the Sol System.

Article

This dwarf planet was the first Kuiper Belt object to ever be discovered and is primarily made of ice and rock.

Article

A gas giant best known for its set of planetary rings.

Article

This ice giant has an unusual lopsided magnetic field due to a dramatic tilt of its axis that places its north and south poles where most other planets have their equator.

Article

Venus’s atmosphere is almost entirely composed of carbon dioxide, which makes it the hottest planet in the Sol System.

Article

The surface of this moon is crisscrossed by an extensive network of scarps, canyons, and ridges. Scientists speculate some of these canyons were carved out by liquid ammonia, methane, or carbon monoxide.

Article

The tidally locked surface of Callisto is the oldest and most heavily cratered in Sol.

Article

The gravitational influence of Charon on Pluto is such that the pair has been classified and unclassified as a binary dwarf planet multiple times since its discovery in 1978.

Article

With a radius of only 6.2 kilometers, Deimos' size and lumpy shape bear more of a resemblance to an asteroid than a moon.

Article

Strangely, this tidally locked moon features numerous impact craters on its trailing hemisphere, leading scientist to speculate that heavy bombardment from objects once spun Dione 180 degrees.

Article

Europa's icy surface makes it one of the most reflective moons in the Sol System.

Article

Ganymede is the Sol System’s largest moon and the only one with a magnetosphere. It is bigger than Mercury and only slightly smaller than Mars.

Article

Tidally locked to Saturn, Iapetus is unusual because of its “two-tone” coloration. The side facing Saturn is constantly shrouded in shadow while the more distant side is illuminated.

Article

Thanks to tidal heating, Io experiences extreme geologic activity, making it the driest and most volcanically active object in the Sol System.

Article

A large natural satellite that is tidally locked with Earth. The first celestial object Humanity ever visited.

Article

Miranda is one of the smallest objects in the Sol System known to be in hydrostatic equilibrium. Its extreme and varied topography includes the Verona Rupes, which features the tallest cliff in the system.

Article

Uranus’ second largest moon was named after a mythical faery king from a famous 16th century play. Its surface is covered in impact craters and appears red in color due to space weathering.

Article

Only 6,000 kilometers away, Phobos orbits Mars so fast that it appears to rise in the west and set in the east twice every Martian day.

Article

Made mainly of rock and ice, Rhea is commonly referred to as a “dirty snowball” due to its composition.

Article

Tethys is predominantly made of water ice, which gives it a density much lower than other celestial objects its size.

Article

Saturn’s largest natural satellite has long been of great interest to scientists. With rivers and lakes of ethane and methane, Titan is the only moon in the Sol System with a dense atmosphere.

Article

Titania is Uranus’ largest moon. Enormous canyons and scarps cut through its surface. Scientists believe they were created after an interior expansion occurred during the moon’s evolution.

Article

The largest of Neptune’s moons, it the planet's only natural satellite massive enough to have achieved gravitational rounding.

Article

This moon’s name has its roots in the Latin word “umbra”, which means shadow. An appropriate reference considering Umbriel is the darkest of all Uranian moons.

Article

Though it is no longer in active service since the Marine forces stationed here were reassigned to Mars, the base remains strictly off limits.

This orbital Naval base acts as the main operational center for the main Sol fleet.

Article

A major shipping hub where most cargo moving to Earth is first processed to help alleviate congestion on the Empire’s capital world.

Over half the belt’s entire mass is concentrated in four large asteroids.

Article

Planetary Ring System

The Kuiper Belt consists mainly of small bodies that are believed to be remnants from Sol's formation.
