How many days does it take Neptune to go around the sun?

Answer 1

A year for Neptune is equal to 164.79 Earth years and a "day" is 16.1 Earth hours long. So a Neptune year is equal to 60,910 Earth days or 89,666 Neptune days. Interesting fact : there has not been one full Neptunian year since its discovery in September, 1846. In late June of 2011, we will mark one "year" since its discovery.

Answer 2

Neptune takes a little under 165 years to complete one solar orbit (60,190 earth days).

Answer 3

Earth doesn't rotate around Neptune. Both Earth and Neptune go around the sun.

Answer 4

It is hard to be precise would be about 60,148 days, which is 164 years and about 9 and a half months.
