This list of real and imaginary stars and planets comes from both our local
neighbourhood and from the realms of Science Fiction. For the SF planets,
often not all the details were defined, so I've made some guesses, but
tried to indicate them in the forms.
You can select 2 configurations. Both can be either a standard place ( eg Terran=Sun+Earth+The_Moon)
or a new system composed of pre-defined places
(Sirius, Mars, Ganymede etc) or completely new ones. Whatever you choose,
you'll be able to edit all the details, including the names later, so
choosing 2 Terran systems, one for reference, and one to fiddle with, is a
good starting point. More information on the systems and the science is available.
Rather than split the names into planets and moons, I just refer to
BodyA and BodyB. BodyA orbits the star, BodyB orbits BodyA
