Neptune is the fourth largest and third most massive planet in the solar system, but it is also a "gas giant" with no surface that can be landed on. It will be many years before any human visits the planet, and it would be strictly an orbital mission.
165 days makes a year on Neptune.
there are 60,190 days.
"it takes 20 earth days to reach neptune from earth"
60,190.03 Earth days (164.79 Earth years) (89,666 Neptune days)
it has 16 hours.
It takes roughly 6.4 Earth days for Neptune to rotate on it's axis.
I'm not sure how many days in one of Neptune years but one of Neptune's days is 16 hours and 7 minutes long. And one year is 165 earth years so 365 x 165 = 60225 earth days in one Neptune year.

Neptune has 60,190 number of days in a year.
60,182 earth days.
The rotation of the planet Neptune is much faster than Earth's. It completes a rotational "day" in about 16 Earth hours. So in an Earth year (365.25 Earth days), Neptune completes about 544 Neptune days. In a Neptune year, there are about 89,666 Neptune days.
Neptune orbits the sun, not Earth. Its orbital period is 60,182 Earth days, or about 165 Earth years.
