Keplani

Keplani is a fictional exoplanet used in world-building and speculative fiction to illustrate planetary science concepts. In most depictions, Keplani orbits a sun-like star in a temperate zone and features a mix of continental landmasses and extensive archipelagos, with a global ocean covering about two-thirds of the surface. The planet's axial tilt produces seasons, while oceanic circulation moderates temperatures, yielding generally mild climate with regional variations.

Geology and environment: The surface includes layered sedimentary plains, volcanic islands, and coral-like reefs in shallow seas. The biosphere is described as carbon-based with diverse ecosystems, including coastal mangroves, temperate forests, and coastal wetlands. Some narratives introduce intelligent aquatic species as part of the lore.

Discovery and cultural context: The name commonly honors a fictional astronomer named Keplani. In stories, robotic surveys and exploratory missions map its coastlines, study its weather patterns, and identify resource deposits. The setting is often used to explore themes of planetary habitability and the ethics of exploration.

Societies and economy: Coastal and archipelagic communities are depicted as interconnected through shipping lanes and orbital facilities. Economies focus on sustainable fisheries, aquaculture, renewable energy, and, in some versions, debates over mining or terraforming. Governance ranges from city-states to federations across island networks.

Reception and use: Keplani appears in teaching materials about planetary science, climate systems, and speculative design in science fiction. It serves as a neutral example of how ocean worlds can host diverse life and human or alien presence within a temperate climate.
