Mote Prime

Mote Prime has a poisonous atmosphere for humans. It is breathable with the aid of commercial or standard Navy issue filters. Oxygen: 16 percent. Nitrogen: 79.4 percent. CO2: 2.9 percent. Helium: 1 percent. Complex hydrocarbons including ketones: 0.7 percent.

Planets gravity: 0.780 standard. The planetary radius is 0.84, and mass is 0.57 Earth standard; a planet of normal density. Period: 0.937 standard years, or 8,750.005 hours. The planet is inclined at 18 degrees with semimajor axis of 0.93 AU (137 million kilometers).

Temperatures are cool, poles uninhabitable and covered with ice. Equatorial and tropical regions are temperate to hot. The local day is 27.33 hours.

There is one moon, small and close. It is asteroidal in origin and the back side bears the characteristic indented crater typical of planetoids in the Mote system. The moon-based fusion generator and power-beaming station are critical sources for the Mote Prime civilization.

Topography of planet is 50 percent ocean, not including extensive ice caps. Terrain is flat over most of the land area. Mountain ranges are low and heavily eroded. There are few forests. Arable lands are extensively cultivated. The most obvious features are circular formations which are visible everywhere. The smallest are eroded to the limits of detection, while the largest can be seen only from orbit. Inhabited by Moties and plagued by over-population problem.

Star system is called Mote.
