Neptune (the eighth and outermost planet) was discovered on September 23, 1846. It takes 164.79 Earth years to complete one orbit and will therefore only complete its first orbit since its discovery in 2011.
It is also worth noting that while Pluto is not longer regarded as a planet (it is now a minor planet) it was discovered in 1930 and takes 248.09 Earth years to complete an orbit.
