Central Body
Plots generated
by the 3D-viewer are calculated
regarding to a central body , shown in the center
of the plot. In the normal case the sun is selected as central body
and heliocentric positions and orbits are drawn, but it is possible
to specify also each other object from the current body selection as
central object. In this way, it is possible to generate geocentric
or other planetocentric views too. To change the central
object select 3D-Viewer->Heliocentric/planetocentric
view from the main menu. The Central body
dialog appears. Select a body from the list, click OK and all selections are retained and
used for generation of a new plot. In the following examples (1)
a heliocentric, (2) a geocentric, and (3) a martiocentric view of
the same orbits are shown.
