Planets aren't my thing so I only know the one for remembering the spectral classes of stars. Apparently it is now regarded as sexist.

The stellar classification system letters do represent something, although it is not an acronym as was correctly said! When stellar spectra were first observed astrophysicists classified stars on the strength of their Balmer series lines from A (strongest) to Q (weakest). It was later discovered that some of the lines were not Balmer lines but were a result of other elements and compounds so the list was cut and re-ordered leaving us with OBAFGKMN.

Hope this is useful/interesting!
