The sidereal rotation period of Venus is a very long 243.0185 Earth days. That means it takes a bit over 243 Earth days to rotate once on its axis (a Venus sidereal "day"). It gives new meaning to the expression, "It's been a long day."
The rotational velocity at the equator is a blazing 6.52 kilometers per hour (a bit over 4 miles per hour). You can walk that fast if you step out and don't drag your feet. A link can be found below.
Orbital velocity refers to the speed at which a planet travels in its orbit.
According to http://solarsystem.nasa.gov/planets/, Venus has an orbital velocity of 78,341 mph, and Neptune's is 12,253 mph...
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.
Saturn has a slower orbital speed than Jupiter. Saturn's average orbital speed is about 9.69 km/s, while Jupiter's average orbital speed is about 13.07 km/s, making Jupiter about 3.38 km/s faster than Saturn.
The average orbital speed of a planet or other object in orbit round the Sun is propotional to the reciprocal of the square root of the average distance from the Sun. V is proportional to 1/ sqrt (D) This can be derived from Kepler's laws of planetary motion, published in 1609 and still in use.
The planet with an orbital speed of around 30 kilometers per second is Earth. Its average orbital speed around the Sun is approximately 29.78 kilometers per second.
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."
5.43 km per second.

A year is shorter on Venus than on Earth. A year is the time taken for a planet to orbit the Sun. Venus has a smaller orbit and a higher orbital speed.

The orbital speed of a planet is the time it takes to cycle around the sun. The spinning speed of a planet is the time it takes for the planet to rotate on it's axis.
Saturn has a slower orbital speed than Jupiter. Saturn's average orbital speed is about 9.69 km/s, while Jupiter's average orbital speed is about 13.07 km/s, making Jupiter about 3.38 km/s faster than Saturn.
Venus is the slowest planet with a rotational speed of 243 Earth days equaling one Venusian day.
