Best Answer

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)
