Neptune's day is 0.67125 times that of the Earth's
Neptune rotates on its axis once every 16.1 hours, and revolves around the sun in 164.8 earth years.
Rotation: 0.6713 earth days.Revolution: 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.
A year on Neptune takes 164.8 Earth years
Rotation period (length of day in Earth days) 58.65 earth days Revolution period (length of year in Earth days)87.97 earth days
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".
The length of a day on Neptune, also known as its period of rotation, is about 16.1 Earth hours, or 0.67 Earth days. The length of a year on Neptune, also known as its period of revolution, is 164.8 Earth years, or 60,190 Earth days.
Neptune takes 16.1 hours to make a full rotation, which is equivalent to 0.673 Earth days.
Rotation: 0.6713 earth days.Revolution: 60,182 earth days.

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.
