Planetary Data

Geographic Data

Hydrangea is smaller than Earth, with an average equatorial diameter of just over 10,000 km. Surface gravity is about 0.75g. The planet has a breathable (but unpleasant) atmosphere rated at 0.71atm. There are a few muddy flats on the surface, but otherwise Hydrangea is a dry world.


Hydrangea is home to some 6 billion people. People here still dress and speak in an archaic manner, and almost all new media or developments must pass through many government filters before they are adopted. Only about 30% of the population has a comm unit in their home, and most travel and commerce is done with petrochemical-burning engines.


Hydrangea's low-tech factories put out huge volumes of basic machine parts, and outdated pumping systems draw out petrochemicals that are refined and consumed on-planet with surpluses stored in huge tanks near the city of Putnam.

Because of the primitive water recycling facilities, higher-status citizens are willing to pay a premium for imported drinking water.


The government maintains extremely strict controls on all inbound information, practices, and technology in order to keep the population manageable. Hydrangea's ruling party encourages a sparse lifestyle, with any crumbs doled out to privileged underlings, encouraging a culture of favors. Any transactions with offworld organizations are handled by approved officials.

Travellers' Information


Travellers to Hydrangea should be aware that almost anything can be considered suspect by planetary officials. This includes any weapon or computer system, or any device, substance, or information from offworld.

The only starport services offered are crumbling concrete fields around Putnam, so in-system travellers needing fuel are advised to use one of Tyree System's three gas giants.
