Contrary to a previously published claim, it is found that the spheroi
dal galaxies NGC 147 and NGC 185 probably form a stable binary system.
Distance estimates place this pair on the near side of the Andromeda
subgroup of the Local Group. The fact that this system has probably re
mained stable over a Hubble time suggests that it does not have a plun
ging orbit that brings it very close to M31. It is noted that the only
two Local Group galaxy pairs in which the components have comparable
masses also have similar morphological types. NGC 147 and NGC 185 are
both spheroidal galaxies, while the LMC and SMC are both irregular gal
axies. This suggests that protogalaxies of similar mass, that are spaw
ned in similar environments, evolve into objects having similar morpho
logies.
