Central body
From Wikipedia, the free encyclopedia
In astrodynamics a central body (
) is a body that is being orbited by an orbiting body (
). Under standard assumptions in astrodynamics:
- it is more massive than the orbiting body by several orders of magnitude (i.e.
), - it is a center of an inertial frame of reference for the orbiting body,
- it is in the focus (or one of the two) of the orbiting bodies' orbit.
