Yes, Pluto has completed more than one orbit around the sun since it was discovered in 1930.

Here's why:

* Pluto's Orbital Period: Pluto takes approximately 248 Earth years to complete one orbit around the sun.

* Time Since Discovery: Since Pluto was discovered in 1930, it has completed just over one full orbit. It's currently about 2/3 of the way through its second orbit.

Therefore, Pluto has definitely completed at least one full orbit since its discovery.
