extraplanetary
Outside our planet
Extraplanetary means existing or occurring beyond the boundaries of a planet, typically Earth.
The term appears in scientific and science fiction contexts discussing space exploration, celestial phenomena, or life beyond our world: extraplanetary colonization, extraplanetary resources.
It functions similarly to extraterrestrial but emphasizes location rather than origin.
