It takes roughly 165 Earth years for Neptune to complete a rotation around the Sun.
it takes 165 Earth years for Neptune to revolve around the sun.
Now that Pluto has been downgraded to a dwarf planet, Neptune is the most distant planet from the Sun. It takes 164.79 Earth years for Neptune to circle the Sun, so one Earth year would be about 1/165 of a Neptune year (the time it takes Neptune to circle the Sun).
Earth and Neptune formed together so it has lived the same number of Earth Years as Earth has.
One orbit for Neptune takes nearly 165 Earth years (164.79 years). This is approximately 60,190 Earth days. But a day (complete rotation) for Neptune is much shorter than Earth's, about 16 Earth hours. So there are about 89,666 "Neptune days" in a "Neptune year".
60225 earth days = one year on Neptune
165 Earth Years
60,190.03 Earth days (164.79 Earth years) (89,666 Neptune days)
Earth and Neptune formed together so it has lived the same number of Earth Years as Earth has.
Neptune orbits the sun, not Earth. Its orbital period is 60,182 Earth days, or about 165 Earth years.
Neptune takes about 165 Earth years to orbit the Sun. That's one Neptune "year" of course. Neptune's "day" is about 16 hours and 6 minutes ( 16.1 hours). That's the time it takes to spin on its axis once. From that you can work out how many Neptune days the orbit takes, if you want. I make it to be about 89838 "Neptune days". You can say Neptune "year" and Neptune "day", but the terms "week" and "month" are normally only used for planet Earth. Also when I've used "hour" in this answer I mean an Earth hour. This is normal in books on astronomy.

Jupiter orbits the Sun once every 11.9 Earth years, Saturn once every 29.5 Earth years, Uranus once every 84 Earth years, and Neptune once every 165 Earth years.
