In the time it took scientists to discover it, let it be a planet for 76 years, take away its planet status, say it might be a planet again, then change their minds, Pluto never made a full orbit around the sun.  Due to it taking 248.09 Earth years for Pluto to circle the sun, we won’t see it complete an orbit until March 23, 2178.
