Oroga is the sole habitable planet of Kaufman's Other Star (Freusen Durchmusterung Catalog
#4322210351.093), a red Kl star with a luminosity of .252, mass of .725, and radius of .78 relative to
Sol…

Oroga's mean orbital radius is 7.176el2 centimeters—approximately .48 astronomical units. While the
diameter of the primary is roughly three-quarters that of Sol, its apparent size is much greater from the
surface of Oroga than Sol's is from Earth: Kaufman's Other Star occupies almost nine-tenths of a degree
of the sky, appearing to be roughly three times the size that Sol does from the surface of Earth.

The planet's orbit is almost perfectly circular; the eccentricity is only 0.00059… Combined with its low
inclination of 5 degrees, this makes Oroga virtually seasonless.

The atmosphere is breathable without either prosthetic aids or surgical modification… it is slightly richer
in oxygen than Earth's (26%), poorer in nitrogen (72%), and richer in carbon dioxide (.035%); it contains
large but not unhealthful quantities of argon, xenon, neon, and sulfur oxides…

The planet is 73% seas… Of the three major land masses, only a small portion of the most northern has
been settled by humans. The remainder are populated by t'Tant, the native quasi-sapient (see Appendix
for qualification)… Since the t'Tant have no established civilization, population estimates of the native
lifeform are based on orbital photo sampling… Estimates range from less than one billion to more than
1.5 billion.

The majority of the human population lives either in or within one thousand kilometers of Oroga's single
city, Elweré, although there are agricultural townships scattered throughout the inhabited continent. While
the last official census gives the population as 259,276, it counted only citizens, those who actually reside
in Elweré; residents of the areas immediately surrounding Elweré—Middle City and Lower City in the
local parlance—are not legally citizens of Oroga… nor are the workers of the valda and food
plantations…
