The Terra system contains a solitary star, Sol, eight major bodies, numerous minor bodies, one planetoid belt, and one outer cometary belt.
- The mainworld in this star system is the third planet called Terra, which is often still referred to by locals by its archaic name "Earth". Terra has one orbiting minor body known as "Luna" (simply called "the Moon" by locals).
- The Terran star system, sometimes referred to as the Solar System by its residents or the or Sol system by Solomani in general, is unusual in that many marginal worlds that would be ignored in other star systems have been colonized, though many of these settlements have long since been abandoned.
- Terra is the homeworld of one of the major branches of Humaniti, the Solomani. It is widely believed that Terra is also the ultimate origin of all branches of Humaniti in the very distant past.

- Smaller settlements exist on Mercury, Ganymede, Rhea, and Pluto.
- Outposts on Venus and a few satellites have been established for scientific or commercial purposes.
- Luna’s Copernicus Down Spaceport handles traffic control for Terra.
- Traffic in the outer system is controlled from Rhea.
Luna is the proper name for Terra's single large satellite, though most locals simply call it "The Moon". It has a political status equivalent to one of Terra's continents.
- Archimedes Settlement: Domed lunar city. Archimedes is Luna's oldest settlement and main mining and industrial center.
- Archimedes Station: No information currently available.
- Copernicus Settlement: Domed lunar city. Copernicus is the seat of government on Luna, and the center of travel and trade. Copernicus Down Spaceport handles traffic control for Terra. Since the Solomani Rim War, more than half of the terminals, bays, and warehouse facilities of the spaceport lie unused and in vacuum.
- Plato Settlement: Domed lunar city. Plato is an academic and cultural center, and the location of the University of Luna which is famous for work in high-energy physics and astronomy.
- Clavius: Clavius crater is the site of a high-technology industrial park producing electronic and gravitic components, vacuum-process equipment, and thin-film devices. It is currently operated by GSbAG.
- Clavius Particle Research Complex is run jointly by the Imperial Navy and Naasirka. Current research is highly classified.
- Farside Research Station: Farside Station is famous for work in cosmic ray research and radio-astronomy. It is operated as a branch of the University of Luna, and its vast distributed arrays cover cover thousands of square kilometers on the lunar hemisphere facing away from Terra. Development and travel on the far side of Luna is restricted in order to avoid interfering with the institute's research programs.

- Syuki Solar Observatory: The Syuki Solar Observatory is a large facility comprised of over 10000 people conducting many and varied studies of the Terran system's central star.
- Venus has a dense atmosphere of 96.5% CO2 and 3.5% N2, with an atmospheric pressure of 90 atm and an average surface temperature of 460o Celsius. Sulfuric acid rain falls in the upper atmosphere, but does not reach the surface.
- Largely unexplored, manned expeditions beginning in AD 2830 revealed evidence of long extinct life, and that Venus had once been the site of an unfinished Ancients terraforming project that had been been interrupted (apparently) by the Final War. The current conditions on Venus are the result of the ensuing and uncontrolled runaway greenhouse. There is an orbital science station that still studies these Ancient ruins, of which most have been almost completely destroyed by the local environmental conditions.
Mars began to be terraformed by the Solomani beginning in approximately Imperial year 400. The former trace CO2 atmosphere has been greatly thickened by the addition of O2, raising the atmospheric code of the world to "Very Thin". There is the possibility that within the next century hydrological weather patterns will begin to form.
- Phobos (Asteroidal-moon): No information available.
- Deimos (Shattered Moon): This former asteroidal-moon of Mars was shattered during the Solomani Rim War, at which time it was the location of a Solomani naval installation.
- The Martian Restoration Project: This settlement includes the majority of the world's inhabitants.
- Elysium Plateau Imperial Marine Base: No information available.
- Olympus Mons: No information available.
- Candor Chasma: Location of Martian capital city.
The Main Belt of the Sol system is the original location of the discovery of Jump Drive by the ancient Solomani.
- Ceres: Ceres is a dwarf planet and the largest member of Sol's Main Belt at almost 1000 km in diameter. It is the site of the largest settlement in the Belt.
- Vesta: No information available.
- Pallas: No information available.
- Juno: No information available.
- Amor: This asteroid has been hollowed out and currently houses a colony of Dolphins, most of whom are artists.
The Jovian System (significant bodies)
Jupiter is the largest of the four Gas Giants in the Terra system, and has four significant satellites.
- Io: Io has a trace atmosphere largely composed of SO2. Active volacanism on the surface produces both sulfur and SO2.
- Europa: No information available.
- Ganymede: Ganymede is the largest moon in the Sol system. Once a major colony, today Ganymede still hosts several facilities.
- The Kensington Armed Forces Testing Center is a naval research laboratory.
- The Zeus Institute is a branch of the University of Terra, studying gas giants and their dynamics.
- Callisto: Callisto hosts the Byahnn Research Facility. Originally a Solomani weapons center, under Imperial authority it is dedicated to the study of Jovian meteorology. Callisto is also home to an Imperial fighter and system defense boat base that patrols the Jovian system and the outer gas giants.
The Saturnian System (significant bodies)
Saturn is the second largest of the four Gas Giants in the Terra system, and possesses a brilliant ring system of reflective small ice-bodies that is used extensively for refuelling.
- Janus: No information available.
- Mimas: No information available.
- Enceladus: Enceladus is home to the Huygens Astrophysical Outpost. While the research is secret, speculations suggest that the facility may be devoted to antimatter research.
- Tethys:No information available.
- Dione: No information available.
- Rhea: Rhea hosts the Cassini Starport, which serves as the traffic control center for Terra's outer system. It also houses an associated underground base currently run by the IISS.
- Titan: Titan has a thick atmosphere (~ 1.4 atm) composed of 98.5% N2 and 1.5% CH4. The surface tempertaure of 93.7K is close to the triple-point of methane (CH4), meaning that methane can be found in solid, liquid, and gaseous phases. Its icy surface is pock-marked with methane and hydrocarbon lakes. Currently there is only a single domed facility active on Titan which studies evolving methane-based bacteriological life in Titan's lakes. The origin of this life seems to be a result of contamination by ancient industrial processes active during the Long Night. Titan is also known as an Ancient site.

History & Background (Dossier)
Many marginally habitable environments with in the Terran system were populated before the advent of FTL spaceflight. Many of these marginally habitable environments have been abandoned since the advent of FTL spaceflight.
