- 165 years -- one orbit of Neptune
- 247.7 years -- one orbit of PlutoPluto is the ninth planet from the Sun in our solar system. Because Pluto is also the smallest planet in our solar system and has a highly eccentric orbit (which takes it inside the orbit of Neptune) there has been some debate regarding whether Pluto shou
