Triton (Sol 8a)

Moons

Triton is a moon of Neptune (Sol VIII), United Empire of Earth (UEE). The largest of Neptune's moons, it the planet's only natural satellite massive enough to have achieved gravitational rounding. Additionally, even though it is a moon, it is larger than all other dwarf planets…

Penselin (Davien 2a)

Moons · Human

Penselin is the moon of Cestulus (Davien II), a planet in the United Empire of Earth (UEE). It was named for Dr. Daniel Penselin, a physicist who died there testing his improvements to the quantum drive. Its radius is only a few meters longer than that of Earth's moon.

Titania (Sol 7d)

Moons

Titania (Sol 7d) is a moon of Uranus (Sol VII), United Empire of Earth (UEE). The largest of Uranus' moons, its surface is scored with enormous canyons and scarps. Under its surface is a mantle of slushy ice that sits over a solid rocky core. It has a tenuous atmosphere of…

Fairo (Pyro 5d)

Moons

Fairo is the fourth moon from the gas giant Pyro V, Pyro system. A hotbed of seismic activity, Fairo experiences frequent earthquakes that disturb its deep oceans of brackish water. The moon has an unusual ecosystem that thrives both on the surface and under the sea, supported…

Caliban 3b

Moons

Caliban 3b is the second moon from the surface of Caliban III, Caliban system, located in Vanduul territory. Much smaller than its companion moon, it is porous, ovoid, and low in mass. It was most likely captured from the nearby Caliban belt alpha sometime before it was…

Caliban 4b

Moons

Caliban 4b is the second moon from the gas giant Caliban IV, Caliban system, located in Vanduul territory. Enveloped by a weak magnetosphere, it is encircled by a pair of auroral belts that generate shimmering red light shows when the moon's magnetic field interacts with that of…

Ariel (Sol 7b)

Moons

Ariel (Sol 7b) is a moon of Uranus (Sol VII), United Empire of Earth (UEE). Scientists speculate that the many scarps, canyons, and ridges carved into the moon's surface were created in the distant past by liquid forms of ammonia, methane, or carbon dioxide. The UEE operates…

Caliban 4d

Moons

Caliban 4d is the fourth moon from the gas giant Caliban IV, Caliban system, located in Vanduul territory. Composed of silicate rock, it has a water-ice crust with a very smooth surface that completely covers a moon-wide ocean of liquid salt water. The ice is laced with dark…

Vuur (Pyro 5f)

Moons

Vuur is the sixth moon from the gas giant Pyro V, Pyro system. Thanks to an increased greenhouse effect in its dense carbon dioxide atmosphere, it is unusually warm for a moon so distant from its sun. Its carbon-rich soil supports forms of vegetation that utilize crystalline…

Caliban 4a

Moons

Caliban 4a is the first moon from the gas giant Caliban IV, Caliban system, located in Vanduul territory. Iron-rich and very dense, studies conducted on the moon have shown that it is likely older than any other celestial body in the system. Astronomers hypothesize that it is…

Umbriel (Sol 7c)

Moons

Umbriel (Sol 7c) is a moon of Uranus (Sol VII), United Empire of Earth (UEE). One of the darkest in color of the moons of Uranus, one of its larger craters has a ring of reflective material on its floor, making Umbriel appear as if it has a single small eye. Visual artist Tamsa…

Min 1a

Moons

Min 1a is the closest moon to the rogue planet Min I in the unclaimed Min system. Due to the forces of tidal heating, Min 1a is intensely geologically active, with a network of volcanoes that produce plumes of sulfur that can climb hundreds of kilometers above its surface. Lava…

Ignis (Pyro 5a)

Moons

Ignis is the innermost moon of the gas giant Pyro V, Pyro system. The canyons and dry riverbeds on its surface suggest that liquid water once flowed there in the distant past. Its frigid average temperature and deadly atmosphere of sulfur dioxide creates an unfriendly…

Tethys (Sol 6c)

Moons

Tethys (Sol 6c) is a moon of Saturn (Sol VI), United Empire of Earth (UEE). One of the least dense of all the major moons in the Sol system, it is made almost entirely of water ice. Due to tidal and rotational forces, it is not quite round, taking a slightly elliptical shape.…

Lanisto (Tyrol 1a)

Moons

Lanisto (Tyrol 1a) is the moon of Tyrol I, the closest planet to the two stars of the unclaimed Tyrol system. There is evidence that many years in the past, Lanisto was very geologically active. Empty lava caverns provide temporary shelter to those who want to escape the heat of…

Titan (Sol 6a)

Moons

Titan (Sol 6a) is a moon of Saturn (Sol VI), United Empire of Earth (UEE). The largest of Saturn's moons, its nitrogen-methane atmosphere is denser than that of Earth (Sol III). Titan is dotted with lakes and rivers of liquid hydrocarbons, and its climate has created surface…

Min 1d

Moons

Min 1d is the most distant moon from the rogue planet Min I in the unclaimed Min system. Unlike the other moons in its system, it doesn't experience tidal heating, and has no detectable tectonic activity. Its surface is nearly saturated with craters. So many objects have made…

Ellis 5b

Moons

Ellis 5b is the second moon of Noble (Ellis V), United Empire of Earth (UEE), and is tidally locked to the planet. Nearly three times larger than its sister moon Ellis 5a, the light reflected off its pristine white surface is sometimes bright enough that Ellis 5a becomes…

Min 1c

Moons

Min 1c is the third moon from the rogue planet Min I in the unclaimed Min system. The smallest of the four moons, it has a thin atmosphere of nitrogen and carbon dioxide, and is composed of rocky material and water ices. Like its neighbors, Min 1c experiences tidal heating,…

Dione (Sol 6d)

Moons

Dione (Sol 6d) is a moon of Saturn (Sol VI), United Empire of Earth (UEE). Marked with numerous impact craters and chasmata, it is theorized that Dione went through a period of heavy meteor strikes in the distant past that turned the moon 180 degrees on its axis. After the…

Deimos (Sol 4b)

Moons

Deimos (Sol 4b) is the second and farthest moon from the surface of Mars (Sol IV), United Empire of Earth (UEE). At only 6.2 kilometers in diameter, it bears a strong resemblance to an asteroid. One leading theory proposes that it originated as a part of a larger asteroid that…

Adir (Pyro 5c)

Moons

Adir is the third moon from the gas giant Pyro V, Pyro system. Jagged mountains and rocky hills dominate its crater-ridden landscape. Because it lacks a protective atmosphere that would otherwise break apart most approaching celestial objects, its surface sees frequent impacts.…
