Close to 164 (earth) years and 10 months (164.79 years). While Neptune orbits the sun at the shocking speed of 5.43km/sec (which is almost 20,000 kph or 12,000 mph), since the time it was discovered it still has not completed one of its years. It will have done so on July 12, 2011.

The rotation period (its day) is 0.67 (earth) days.

In Earth years Neptune takes about 165 years to orbit the sun. In Neptune days, it would be a little under 90,000 revolutions.

What planet has a year 165 earth years long?

The answere is planet neptune, the reasons are that neptune has 165 days because is the 8th planet from the sun what it means that is the last planet in the solar system and earth is the 3rd one so it has less days than neptune and if neptune is the last planet thats why it has 165 days.

How many earth years equal to one year in Neptune?

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).
