planetei

Planetei is a fictional planet used in worldbuilding and speculative fiction. In the published setting, it is described as a terrestrial world with Earth-like gravity and an ocean-dominated surface. The name Planetei appears to be a constructed term, drawing on the word planet and a suffix used by the setting’s linguistics to denote a class of worlds.

Physical characteristics: Planetei has a radius approximately 1.3 times that of Earth and a mass around 2 Earth masses, yielding a surface gravity near 1.1–1.2 g. The atmosphere is primarily nitrogen and oxygen with trace gases, producing surface air pressures close to 1 atmosphere. Global mean temperatures are temperate, with regional variation due to oceans and topography. Oceans cover about two-thirds of the surface.

Orbit and rotation: Planetei orbits a G-type main-sequence star at a distance that yields a solar year of roughly 380 Earth days. It spins with a 24-hour day and an axial tilt near 22 degrees, giving seasonal cycles. Its orbit and climate accommodate diverse biomes along coastlines and inland basins.

Geography and geology: The planet features several major continents separated by wide seas. Plate tectonics create mountain belts, island arcs, and active volcanism along rift zones. Climate zones range from temperate coasts to arid interiors, with weather influenced by sea-surface temperatures and atmospheric circulation.

Life and human activity: The canonical narrative leaves Planetei without confirmed indigenous megafauna; some sources propose microbial life in oceans. Planetei is widely used as a setting for exploration, research stations, and colonization narratives, hosting varied human and nonhuman settlements and a range of culturally diverse communities.
