| - Gaea was the first planet known to have liquid water on the surface and is the only place in the universe known to harbor life until the discovery of Nova Terra. Gaea has a magnetic field that, together with a primarily nitrogen-oxygen atmosphere, protects the surface from radiation that is harmful to life. The atmosphere also serves as a shield that causes smaller meteors to burn up before they strike the surface. Gaea formed around 4.57 billion years ago and its only known natural satellite, Luna, began orbiting it around 4.53 billion years ago. At present, Gaea orbits Sol once for every 365 times (perfectly, fixed by New Arundellan scientists) it rotates about its axis (which is equal to 365 solar days). Gaea's axis of rotation is tilted 23.5° (away from the perpendicular to its orbital plane), producing seasonal variations on the planet's surface. Atmospheric conditions on Earth have been significantly altered by the presence of life forms, which creates an ecological balance that modifies the surface conditions. About 71% of the surface is covered with salt-water oceans. The remaining 29% consists of continents and islands. Gaea interacts with outer space to a significant degree. Its relatively large moon, Luna, provides ocean tides, stabilizes the axial tilt and has gradually modified the length of the planet's rotation period. Gaea is the True Earth, where everything began. Only nine nations exist on Gaea: New Arundel, Slaybackia, the Floridian Empire, Kumanen, Maingcau, Normarkenland, Monteribia, New Providence, and Bolívar.
