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.
At its Equator, the rotational speed is about 9660 km/hour (2.68 km/sec).
(This is nearly 10 times as fast as Earth.)
Neptune spins at a rate of 9,660 km/hr. It takes Neptune 16 hours, 6 minutes and 36 seconds to rotate once on its axis.
Neptune orbits the sun once every 164.79132 years.
(About 164 years and 289 days.)
Neptune spins once on its axis every 16 hours and 36 seconds. Its rotational speed is 9,660 kilometers per hour.
It takes about 165 Earth years to go once round the Sun.
The average speed of the planet in its orbit is about 5.43 km/sec.
it takes ( one Neptune's year) 164 earth year
Neptune takes 164.79 Earth years to orbit the sun once.
It take 164 Earth years for Neptune to orbit around the sun once.
No, Neptune orbits around the Sun.
Neptune
None. Moons orbit Neptune. Planets orbit the Sun
According to Kepler's laws of planetary motion, its distance from the sun.
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 164.79 Earth years to orbit the sun once.
Neptune would orbit at 111,920,000 miles if the orbit was 96% closer to the Sun.
If you still consider Pluto to be a planet then Pluto would be the slowest to orbit the sun. If you don't believe Pluto is a planet anymore then Neptune would be the slowest planet to orbit our 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.
It take 164 Earth years for Neptune to orbit around the sun once.
No, Neptune orbits around the Sun.
Neptune
Neptune orbits the sun at around 4.5 million kilometers. Neptune follows an elliptical orbit around the sun so its orbital distance varies.
Yes it does.
