it has 16 hours.
16 hours or 0.67125 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.
16 hours, or more precise 0.67125 earth days.
Neptune takes 16 hours 6 minutes and 36 seconds to rotate or spin once on its axis, or 0.67125 Earth days.
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.
16.1 hours
A day on Neptune is 16 hours, 6 minutes and 36 seconds.
Neptune takes 16.1 hours to make a full rotation, which is equivalent to 0.673 Earth days.
165 days makes a year on Neptune.
it takes Neptune164 earth years to orbit the sun and a 16 Earth hours
All of them.
