TECHNICAL DEFINITION

Interplanetary describes the domain of space between planets within a solar system, encompassing the trajectories, environments, and missions involved in travel or communication between these celestial bodies.

BACKGROUND

Outer space, or simply space, is the expanse that exists beyond Earth's atmosphere and between celestial bodies. It contains ultra-low levels of particle densities, constituting a near-perfect vacuum of predominantly hydrogen and helium plasma, permeated by electromagnetic radiation, cosmic rays, neutrinos, magnetic fields and dust. The baseline temperature of outer space, as set by the background radiation from the Big Bang, is 2.7 kelvins.
