Kerbins

Kerbins is a term used in science fiction and fan-created lore to denote a group of planetary bodies associated with Kerbin, the central world in certain fictional universes. The exact meaning varies by author, but Kerbins is typically used to refer to the Kerbin system or to Kerbin-like planets across a star system. The name is derived from Kerbin and uses the plural suffix -s to indicate multiple worlds or a collective of Kerbin-associated bodies.

In most depictions, Kerbin is a terrestrial planet with an atmosphere and oceans. Its satellites, such as Mun and Minmus in popular fan extensions, are depicted as significant bodies in orbit around Kerbin, though not all works include the same moons. Beyond a few major moons, Kerbins fiction may include dwarf planets, asteroid belts, or orbital stations, with spaceflight and exploration playing central roles in the setting.

The term is used by fans to describe the broader Kerbin-inspired milieu, including culture, technology, and political actors that appear in stories about interplanetary travel, space programs, or colony-building. Because Kerbins is primarily found in fan content, there is no single canonical description; details vary between works.

Related terms include Kerbin, Mun, Minmus, and Kerbal Space Program, which provide context in shared or derivative works.
