Sidoas

Sidoas is a fictional planet featured in the science fiction novel "The Mote in God's Eye" by Larry Niven and Jerry Pournelle. It is the homeworld of the Moties, an alien species with a complex and highly structured society. Sidoas is depicted as a world with a challenging environment, which has significantly shaped the evolution and behavior of its inhabitants.

The planet's gravity is higher than Earth's, and its atmosphere is denser, influencing the Moties' physical characteristics, such as their stocky build and strong limbs. Sidoas experiences extreme temperature fluctuations and possesses unique geological features, contributing to the Moties' resourcefulness and their advanced technological development. The Moties' society on Sidoas is characterized by a rigid caste system and a strong emphasis on survival and expansion, driven by the limited resources and harsh conditions of their homeworld. Their history is marked by periods of intense conflict and cooperation, all stemming from the pressures of life on Sidoas. The planet's ecosystem is also a key element, with its own set of flora and fauna that the Moties have learned to manage and exploit.
