UEE

Sol System

The birthplace of Humanity and capital of the Empire. The Imperator, Senate and many other major UEE institutions are based on Earth (Sol III). Among the many historical milestones that the system can lay claim to is the first planet terraformed by Humans, Mars (Sol IV).

Planets

Name Type Size Status Description
Mercury Iron Planet 2,439.7 km Due to an orbital eccentricity, this small planet experiences the greatest temperature variations of any planet in the system.
Venus Smog Planet 6,051.8 km Venus’s atmosphere is almost entirely composed of carbon dioxide, which makes it the hottest planet in the Sol System.
Earth Terrestrial Rocky 6,371 km Habitable 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.
Mars Desert Planet 3,389.5 km Habitable 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.
Jupiter Gas Giant 69,911 km This gas giant is the largest planet in the Sol System.
Saturn Gas Giant 58,232 km A gas giant best known for its set of planetary rings.
Uranus Ice Giant 25,362 km 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.
Neptune Ice Giant 24,622 km An ice giant whose differential rotation contributes to it having the strongest winds in the Sol System.
Pluto Dwarf Planet 1,186 km This dwarf planet was the first Kuiper Belt object to ever be discovered and is primarily made of ice and rock.

Moons

Name Type Size Status Description
Luna Planetary Moon 1 km A large natural satellite that is tidally locked with Earth. The first celestial object Humanity ever visited.
Io Planetary Moon 1 km Thanks to tidal heating, Io experiences extreme geologic activity, making it the driest and most volcanically active object in the Sol System.
Europa Planetary Moon 1 km Europa's icy surface makes it one of the most reflective moons in the Sol System.
Ganymede Planetary Moon 1 km 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.
Callisto Planetary Moon 1 km The tidally locked surface of Callisto is the oldest and most heavily cratered in Sol.
Titan Planetary Moon 1 km 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.
Rhea Planetary Moon 1 km Made mainly of rock and ice, Rhea is commonly referred to as a “dirty snowball” due to its composition.
Tethys Planetary Moon 1 km Tethys is predominantly made of water ice, which gives it a density much lower than other celestial objects its size.
Dione Planetary Moon 1 km 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.
Iapetus Planetary Moon 1 km 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.
Miranda Planetary Moon 0.3 km 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.
Ariel Planetary Moon 0.6 km 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.
Umbriel Planetary Moon 0.65 km 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.
Titania Planetary Moon 0.8 km 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.
Oberon Planetary Moon 0.75 km 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.
Phobos Planetary Moon 0.11 km 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.
Deimos Planetary Moon 0.062 km With a radius of only 6.2 kilometers, Deimos' size and lumpy shape bear more of a resemblance to an asteroid than a moon.
Charon Planetary Moon 1.604 km 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.
Triton Planetary Moon 0.1353 km The largest of Neptune’s moons, it the planet's only natural satellite massive enough to have achieved gravitational rounding.

Stations & Orbital Platforms

Name Type Size Status Description
TDD Kesner Space Station Habitable A major shipping hub where most cargo moving to Earth is first processed to help alleviate congestion on the Empire’s capital world.
IMS Bolliver Space Station Habitable Though it is no longer in active service since the Marine forces stationed here were reassigned to Mars, the base remains strictly off limits.
INS Dunleavy Space Station Habitable This orbital Naval base acts as the main operational center for the main Sol fleet.
