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