The planet with the longest orbit in our solar system is Neptune. It takes approximately 165 Earth years to complete one orbit around the Sun. This extended orbital period is due to its great distance from the Sun, located about 30 astronomical units away. Consequently, Neptune's last complete orbit was finished in 2011, after being discovered in 1846.
