Mark is right.	To really do jump limits right you should base it on the
mass
of the star and then add spectral color and age as background.	This
background will influence type of planets, etc., so it is useful.  Also
remember that most stars are in multiple star systems, not counting
brown
dwarfs.  Some astronomers swear Jupiter is a brown dwarf, so Sol just
might
be a binary star system too.
