The planet Neptune takes about 16 hours, 6 minutes, 36 seconds for one complete rotation, as evidenced by its visible outer atmosphere. This is a "day" on Neptune.
That's about 2/3rds of an Earth Day. Note that the period of rotation is measured by watching Neptune's magnetic field. The time cited is the time it takes the "whole planet" to rotate once on its axis. This is important because Neptune is not solid - it's a gas planet, and gas rotates differentially. Around the equator, the rotational speed of the "air" there is about 18 hours, and the rotational speed for the "air" at the poles is about 12 hours.
The rotation period (day) of Neptune's interior of 16 hours, 7 minutes was determined by Voyager 2. This was the first reliable determination of Neptune's rotation period. The 12 to 18 hour rotation periods found for the atmospheric features differ from the above value because of winds.
Neptune's orbital velocity is 5.43 km/sec (nearly 20,000 kph or 12,000 mph).
Estimate by Computation
To estimate the distance Neptune travels in one orbit around the Sun : 2πr where the average radius is 4.5 x 109 km and the corresponding circumference 28.3 x 109 km. Given the computed orbital time of 164.79 Earth years, and Speed = Distance / Time, the estimate is 19,590 km/hr. (3600 seconds x 5.43 m/sec - 19,548 km/hr)
The planet's equatorial rotation speed is 2.68 km per second, so that it completes one spin (day) every 16.1 Earth hours.
The maximum spin is about 6,000 mph, about six times faster than on Earth. However, because the planet's outer layers are not solid, observed features move at different speeds depending on their latitude.
No, Neptune does not orbit around Uranus. Both Neptune and Uranus orbit around the Sun in separate orbits.
Neptune stays in orbit around the Sun due to the gravitational pull between the two bodies. The Sun's gravity keeps Neptune in its orbit, just as it does for all the other planets in the solar system. This balance between the Sun's gravitational pull and Neptune's orbital speed keeps it from moving away or falling into the Sun.
Neptune takes about 165 Earth years to complete one orbit around the sun. Its distance from the sun and its slow orbital speed contribute to its lengthy orbital period.
Neptune takes approximately 165 Earth years to orbit the sun once.
Neptune takes approximately 165 years to orbit the sun once.

According to Kepler's laws of planetary motion, its distance from the sun.
Neptune takes about 165 Earth years to complete one orbit around the sun. Its distance from the sun and its slow orbital speed contribute to its lengthy orbital period.
Neptune takes approximately 165 Earth years to orbit the sun once.
Neptune orbits the Sun (as do most planets) with an elliptical orbit. When the orbit takes the planet closest to the Sun it is moving faster than when it is furthest from the Sun when on an elliptical orbit.
Neptune takes approximately 165 years to orbit the sun once.
Neptune's year lasts about 164 Earth years. It takes Neptune 164.79 Earth years to orbit the Sun once due to its slow orbit speed and distance from the Sun.
Neptune would orbit at 111,920,000 miles if the orbit was 96% closer to the Sun.
The planet that moves around the Sun the slowest is Neptune. Neptune takes about 165 Earth years to complete one orbit around the Sun.
It takes about 164 years, nine and a half months for Neptune to orbit the Sun.
Neptune is about 30 times farther away from the sun than Earth is.
