Another consequence I've found playing with my extended system
generator is that a few systems come up with a Star or a gas giant in
the habitable (or one of the habitable) zones of the primary
star. If these systems orbit a star it's usually a tiny Mx V companion
which contributes very little heat to the subject planets.

For a planet orbiting a companion star I take the temperature to be
greater of the temperature gained from the companion and the
temperature provided by the primary. What that means is that in such a
system there will be many habitable worlds.

What would such systems look like in the real world?

I ask because I dimly recall that in the Joss Whedon's Firefly 'verse
he dodged the question of FTL drives by having his setting be a system
with multiple planets and moons in the habitable zone of their
star(s).

I would think that such a system could be interesting but the
Traveller system doesn't seem to embrace such things. There is a
mainworld that has the system tech level, trade classification, etc.

Does anyone have thoughts about better ways to represent such
systems? For example: A system with a small vacuum world as mainworld
and a subordinate F466nnn-t planet only registers as "Farming" and
does not make the system "Agricultural".
