Orcus

Orcus is a Sol System Kuiper belt object with a large moon, Vanth. Sol System's "fourth dwarf" discovered by Michael E. Brown's team in 2004 CE.

 Union Planet

 Radius in km: 784±23.

Surface Gravity: 0.23g

 Orcus is a plutino, locked in a 2:3 resonance with Neptune, making two revolutions around Sol to every three of Neptune's. This is much like Pluto, except that it is constrained to always be in the opposite phase of its orbit from Pluto: Orcus is at aphelion when Pluto is at perihelion and vice versa. Because of this, along with its large moon Vanth that recalls Pluto's large moon Charon, Orcus has been seen as the anti-Pluto.

The surface of Orcus is relatively bright with albedo reaching 30%, grey in color and water-rich. The ice is predominantly in crystalline form, which may be related to past cryovolcanic activity. Other compounds like methane or ammonia are also present. The mass of the system is approximately equal to that of Tethys. The diameter of Orcus is 784±23 km and the diameter of Vanth is 322 ±55  km depending on their relative albedos.

First surface survey was conducted by an United Earth team under the lead of United Earth Space Force Captain Rick Sanchez in 2098 OTT.

Orcus was placed on the Open list and the first colonist arrived in 2105.

Initial industry was mining and water production.

Today it features a Solar Defense fort and patrol craft capability, (part of the Sol Defense Force. )

It imports tech and general groceries.

Orcus is a quiet world. Residents seek recreation mostly at other places in the Sol System.

About 600,000 citizens make Orcus their home.

Civics are managed by an Administrator that is hired by an elected council.

There are Union Schools, a Union Post Office, Trans Matter Tunnel and Space Tram connections to Sol Hub and TNO hub.
