Orbit mode "Planets plus selected"

[gzotti]

Is your feature request related to a problem? Please describe.
I would like to show the orbit of one object in relation to the orbits of the major planets.

Describe the solution you'd like
We need an orbit selection option: Orbits of the major planets (color coded) which is not mutually exclusive to "selected object only".

Describe alternatives you've considered
Currently it seems this is just not possible. Show thousands of orbits, or one and only.

Additional context
Would be helpful to show where that selected object's orbit lies. Maybe add "last N selected objects", so that more than one can be shown at a time. The planet orbits give the relevant context, obviously.
