(6) Planets of the Star Kingdom of Manticore

Manticore: (Manticore-A III) The capital planet of the Star Kingdom, Manticore's diameter is approximately 13,500 km., with a hydrosphere of 76% and an axial tilt of 5°. This planet is slightly less dense than Earth, with a lower percentage of metals, but still boasts considerable mineral wealth. Average temperatures are close to Earth normal, and the climate is considerably moderated by the lower axial tilt.

Major Manticoran on-planet industries are agriculture, aquaculture, mining, and a well-diversified industrial sector and R&D base. Population as of 1900 pd (280 al) was approximately 1.5 billion. The major shipyards and space industry of the Star Kingdom of Manticore orbit the capital planet.

Sphinx: Sphinx (Manticore-A IV) is larger than Manticore (diameter=16,500 km.) It is also more massive and richer in metals than the capital world. Sphinx is habitable only because an extremely active carbon dioxide cycle effectively extends the liquid-water zone by giving it considerably more "green house" effect than its sister planets, and its hydrosphere is 68% with an axial tilt of 14°, which, coupled with its considerably lower average temperatures, gives it a much more active and less inviting climate than Manticore.

The major on-planet industries of Sphinx are mining, forestry, and animal husbandry (the planet has vast herds of Terran-adapted cattle and native prongbuck). Planet-side industry has been slow to develop but has made considerable ground in the last century. Planetary population as of 1900 pd was 1,048,000,000.

Gryphon: With a diameter of 13,200 km., Gryphon (Manticore-B IV) is actually the most Earth-like (in terms of size and mass) of Manticore's three habitable planets, but its hydrosphere is only 51% and its axial tilt is almost 27°. Coupled with its orbital radius (it is almost as far from the cooler Manticore B as Manticore is from Manticore A), this gives it a rugged "continental" climate with extremely cold winters and (relatively speaking) scorching summers. The planetary biosystem is also the least Earth-like of the Star Kingdom's habitable worlds, and the colony's original cattle did not do well there, but a genetically-engineered variant of the Plains Buffalo, imported from Beowulf (Sigma Draconis) in 1612 pd (113 al), adapted with phenomenal success, and two of the Star Kingdom's major exports to the older planets are buffalo hides and meat. In addition, the Gryphon Kodiak Maximus provides one of the known galaxy's premiere peltries, though the Manticore Charter of Settlement requires that a relatively low ceiling be placed on the pelts taken.

Gryphon is poor in metals (relative to Manticore or Sphinx), and developed planet-side industry is primarily agrarian. Its severe climate has made this planet the last choice for colonization within the system, but, by the same token, this means it has the largest unclaimed areas (particularly with its limited hydrosphere), and it has tended to attract the more adventurous of the last two or three generations, giving it a particularly vigorous population. In addition, it actually has more total industry than Sphinx, despite its limited planetary supply of metals, because of Manticore-B's extensive asteroid belts. The Unicorn Belt's asteroid extraction operations (dominated by the Hauptman Cartel's Gryphon Minerals, LTD., subsidiary) produce the lion's share of the Star Kingdom's raw ores, and most Gryphons who don't want to herd buffalo end up employed in one part or another of their planet's sprawling near-space industrial activities. Perhaps because of this space-going orientation, Gryphon provides a quite disproportionate percentage of the Royal Manticoran Navy's personnel. Indeed, the backbone of the RMN's petty officers come from Gryphon and seem to feel a divine mission to keep the sissies of Manticore-A in shape.

As of 1900 pd, Gryphon had a planetary population of 575,000,000 and a belter population of 298,500,000.
