// ORBITAL LOGISTICS AND PROPULSION TERM
Orbit
An orbit is the curved path an object in space takes around another, larger object due to gravity.
TECHNICAL DEFINITION
An orbit is the gravitationally curved trajectory of an object, such as a planet, moon, or satellite, around a point or another body, typically a larger mass, under the influence of gravity.
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.
