Sol System Description
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 ever terraformed planet, Mars (Sol IV).
Mercury - Sol I
Due to an orbital eccentricity, this small planet experiences the greatest temperature variations of any planet in the system.
Venus - Sol II
Venus’s atmosphere is almost entirely composed of carbon dioxide, which makes it the hottest planet in the Sol System.
Earth - Sol III
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
Mars - Sol IV
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 - Sol V
This gas giant is the largest planet in the Sol System.
Saturn - Sol VI
A gas giant best known for its set of planetary rings.
Uranus - Sol VII
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 - Sol VIII
An ice giant whose differential rotation contributes to it having the strongest winds in the Sol System.
Pluto - Sol IX
This dwarf planet was the first Kuiper Belt object to ever be discovered and is primarily made of ice and rock.
Luna - Sol 3a
A large natural satellite that is tidally locked with Earth. The first celestial object Humanity ever visited.
Io - Sol 5a
Thanks to tidal heating, Io experiences extreme geologic activity, making it the driest and most volcanically active object in the Sol System.
Europa - Sol 5b
Europa's icy surface makes it one of the most reflective moons in the Sol System.
Ganymede - Sol 5c
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 - Sol 5d
The tidally locked surface of Callisto is the oldest and most heavily cratered in Sol.

Titan - Sol 6a
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 - Sol 6b
Made mainly of rock and ice, Rhea is commonly referred to as a “dirty snowball” due to its composition.
Tethys - Sol 6c
Tethys is predominantly made of water ice, which gives it a density much lower than other celestial objects its size.
Dione - Sol 6d
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 - Sol 6e
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 - Sol 7a
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 - Sol 7b
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 - Sol 7c
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 - Sol 7d
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 - Sol 7e
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.
Herschel Belt - Sol Belt Alpha
Over half the belt’s entire mass is concentrated in four large asteroids.
Kuiper Belt - Sol Belt Beta
The Kuiper Belt consists mainly of small bodies that are believed to be remnants from Sol's formation.
- TDD Kesner
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
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
This orbital Naval base acts as the main operational center for the main Sol fleet.
Phobos - Sol 4a
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 - Sol 4b
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 - Sol 9a
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.
