Interplanetary

Interplanetary refers to the space between planets within a star system. It is derived from the Latin words inter (meaning "between") and planeta (meaning "wanderer" or "planet"). In Hebrew, the term is translated as בין-כוכבי (beyn-kokhavi). Other relevant translations include Interplanetario in Spanish, Interplanétaire in French, and Interplanetar in German. The concept is crucial in the fields of astronomy, astrophysics, and space exploration, as it encompasses the study of the physical and dynamic relationships between planets, their moons, and other celestial bodies within a star system. Interplanetary space is also the domain of spacecraft missions that travel between planets, such as NASA's Voyager and Pioneer probes, which have provided valuable data about the outer regions of the Solar System.
