Neptune spins at a equatorial rate of 2.68 km/sec, or a velocity of 9,660 km/hr (6000 mph).
about 25.7 seconds
According to http://solarsystem.nasa.gov/planets/, Venus has an orbital velocity of 78,341 mph, and Neptune's is 12,253 mph...
average orbital speed of 9.69km/s
The orbital speeds are higher when closer to the sun, but slower and more similar as you move out. The two that are closest in speed are Uranus and Neptune. Uranus at 6.8352 km/sec and Neptune at 5.4778 km/sec.
Orbital velocity refers to the speed at which a planet travels in its orbit.
Pluto orbits the Sun at an average speed of 4.66 km/sec.
5.43 km per second.

average orbital speed of 9.69km/s
It is the orbital velocity (speed and direction) or orbital speed (rate of motion). It is usually stated as "average orbital speed" but is actually "mean orbital speed."
The orbital speeds are higher when closer to the sun, but slower and more similar as you move out. The two that are closest in speed are Uranus and Neptune. Uranus at 6.8352 km/sec and Neptune at 5.4778 km/sec.
As it increases, the orbital speed increases, and the period (time to complete an orbit) decreases, which is why Mercury has the shortest year, and Neptune the slowest orbital speed.
Its average orbital speed is 9.69km/s.
Neptune has an orbital speed around the Sun of about 5.43 km/s (19,548 km/h or 12,146 mph)
Jupiters orbital speed in relation to the sun is 13.07 km/sec on average.
The average orbital speed is 17.882 km/s of asteroid in space
Of the major planets, Neptune. The speed of planets in their orbits is directly related to their distance from the sun. The farther a planet is from the Sun, the slower its orbital speed.
Orbital speed is the velocity (speed) of an object as it travels an orbital path around a reference point.
