Ya, but its a little dated now. Any reference to the number of planets cannot survive the next upstart science teacher pushing out a new definition to get himself on the daily show.
Are you referring to Pluto losing its status as a Planet? That was a complicated process that was based on new discoveries and not some idea by some "upstart science teacher" on the daily show. Keeping Pluto as a planet would have made our definition of planet very wide and to be consistent Ceres should have to be turned back into a planet as well.
