Gaia (Foundation Universe)
Gaia is a fictional planet described in the book Foundation's Edge (1982) and referred to in Foundation and Earth (1986), by Isaac Asimov. The name is derived from the Gaia hypothesis, which is itself eponymous to Gaia, the Earth Goddess.
Gaia is located in the Sayshell Sector, about ten parsecs (32 light years) from Sayshell. It orbits a G-4 class star, and has one natural satellite (50 km or 31 miles in diameter). Its axial inclination is 12°, and a Gaian day lasts 0.92 Galactic Standard Days.
Gaians have long names; the longer the name, the higher their status. They are generally addressed by only one syllable of their name.
