Typhon

Typhon is Earth's closest and most productive neighbor. Constructed and launched by Ærolith Dynamics from the remnants of the asteroid that obliterated much of the Pacific Northwest in Earth's recent history, it is the most successful object in geosynchronous orbit since Earth's original moon. It sits just far enough outside of Earth's Roche limit to avoid being completely torn apart.

It is home to Typhon's five residential towers: Halcyon, Aegis, Minos, Argos, and Orion. When and in what order the towers were constructed is unknown.

Typhon is also orbited by its own inhabited artificial satellite, Mimir-9, which is the location of the home office for Ærolith Dynamics' HR department.
