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.
