 Star-planetbox type boxes 

Not sure about this, but it might be an idea to make a template for the heading row only and subst: it into articles, rather than have a full-blown template structure for the whole table. That might make things both more consistent and easier to manage, so everybody wins. I'll suggest not using the term ""planet"" though: we'd probably want to use such a table for systems such as HD 168443 which contain brown dwarfs. Also, given that the table gets used in a ""planetary system"" section, we probably don't need the caption since this is clear from the context.  "
