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.
From fastest to slowest in terms of average orbital speed around the Sun: Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune
The average orbital speed of Neptune is about 5.43 km/s.
Venus is the smallest planet among Neptune, Venus, Saturn, and Uranus.
Because Venus has less distance to travel, and it has a faster orbital speed than the Earth.

5.43 km per second.
Venus is the slowest planet with a rotational speed of 243 Earth days equaling one Venusian day.
Because Venus has less distance to travel than the Earth and is travelling faster. With an orbital speed of 35.02 km/s and an orbital period of 224.70069 days gives an orbital distance of 679,883,169.35km The Earth has an orbital speed of 29.78 km/s (Slower than Venus) and an orbital period of 365.256 days gives an orbital distance of 939,800,765.95km
The Earth's orbital speed is relatively high compared to the other planets in our solar system due to its closer proximity to the Sun. Mercury has the fastest orbital speed, followed by Venus and Earth. The gas and ice giants like Jupiter, Saturn, Uranus, and Neptune have much slower orbital speeds due to their larger orbits and distances from the Sun.
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.
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.
Mercury has the slowest orbital velocity around the sun compared to the other planets in our solar system. Its average orbital speed is about 47.87 km/s.
Venus is the smallest planet among Neptune, Venus, Saturn, and Uranus.
