Neptune is a barren fluid hellworld with oceans of a liquid other than water such as ammonia, methane, or hydrocarbons, or other exotic liquids.
- This world has no overt population, government, or law level.
- Hellworlds often offer daily, and sometimes hourly, life-threatening situations to their inhabitants.
- This world could be populated if anyone had an inclination to do so...
- It is a member of the Third Imperium in the Sol Subsector of Solomani Rim Sector in the Domain of Sol.
- This world-system hosts a Naval Base, usually associated with military starships, which may be located on or off-world.

System Data
The primary of the Terra system is Sol, an ordinary yellow main sequence star. It has a luminosity of 1 Sol, a mass of 1 Sol, and a diameter of 1.391 million km. Sol retains a family of four inner rocky worlds, a stony planetoid belt, and four outer gas giant worlds – the system is named for Terra, the mainworld.
Neptune
Neptune has a UWP classification of "SGG" and is categorised as an ice giant. It orbits Sol at a mean distance of 30.2 AU (778.5 million km) and has an orbital period of 164 years 299 days. It has a mean rotation period (a local day) of 16.1 standard hours, although the surface is not rigid and different regions of (and altitudes within) the world rotate at different rates. Neptune has a diameter of 49,244 km, a mean density of 1.64 g/cm³, and a surface gravity of 1.13 G. The world has a complex layered internal structure: its surface is defined as the point within the atmosphere where the mean pressure equals one bar (760.0 mm Hg), equivalent to the mean surface atmospheric pressure of Terra.
Core
The core of the world has a diameter of approximately 14,000 km and is primarily composed of small quantities of heavy elements such as nickel (Ni) and iron (Fe), and substantial concentrations of silicates (SiO 4–). The core temperatures exceed 7,000°C and pressures exceed 7 megabars. The core is dynamic and active.
