What do they *mean*?  I would think x3 means the mass and the 
diameter, and possibly whether the planet is "terrestrial" 
or "jovian", how many (possibly zero) natural satellites it has, 
etc.  "Orbital parameters" (x4)  means its period, semi-major axis, 
eccentricity, the angle of inclination to the ecliptic, etc.

How you would *use* any of this in a sentence?  I have no effin' clue.
