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.

∙ 14y agoNeptune'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)

∙ 10y agoThe 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.

What keeps Neptune in our solar system in orbit around the sun?
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.
Does Neptune orbit around Uranus?
No, Neptune does not orbit around Uranus. Both Neptune and Uranus orbit around the Sun in separate orbits.
How long dose it take for neptune to orbit 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.
Time it takes the planet Neptune to orbit the sun?
Neptune takes approximately 165 Earth years to orbit the sun once.
What is the length of time ti takes Neptune to orbit the sun?
Neptune takes approximately 165 years to orbit the sun once.
Does Neptune orbit around Uranus?
No, Neptune does not orbit around Uranus. Both Neptune and Uranus orbit around the Sun in separate orbits.

What determines the speed of orbit on Neptune?
According to Kepler's laws of planetary motion, its distance from the sun.
How long dose it take for neptune to orbit 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.
Time it takes the planet Neptune to orbit the sun?
Neptune takes approximately 165 Earth years to orbit the sun once.
When does Neptune orbit the Sun fastest?
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.
What is the length of time ti takes Neptune to orbit the sun?
Neptune takes approximately 165 years to orbit the sun once.
What planets year would last 164 of your earth years?
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.
What would Neptune's orbit be if it orbited 96 percent closer to the Sun than it does?
Neptune would orbit at 111,920,000 miles if the orbit was 96% closer to the Sun.
What planet moves around sun the slowest?
The planet that moves around the Sun the slowest is Neptune. Neptune takes about 165 Earth years to complete one orbit around the Sun.
How long does Neptune take to orbit the Sun compared to the earth?
It takes about 164 years, nine and a half months for Neptune to orbit the Sun.
How much farther from the sun is the orbit of Neptune than the orbit of the Earth?
Neptune is about 30 times farther away from the sun than Earth is.
