[lojban-beginners] mluni and lunra

["moorkids@juno.com" <moorkids@juno.com>]

Hi,
Just wondering ...

Why are both mluni and lunra necessary?

mluni: x1 is a satellite/moon orbiting x2 with characteristics x3, orbital parameters x4
lunra: x1 is a major natural satellite/moon of planet x2; x1 is Earth's moon [default]

The only difference (I notice) between the x1 and x2 of both is lunra is a natural satellite where mluni is any satellite (natural or unnatural).  Other than that mluni just seems to expand upon lunra.  Is the only purpose for lunra is to specify the "natural" of the satellite (couldn't that be specified in mluni's x3?) and to serve as a default for our moon?

Just something kinda strange I was wondering about. : )
