What is Venus's average orbital speed around the Sun?

Venus’s average orbital speed around the Sun is 35.02 km/s.

This is the mean speed Venus has as it travels around the Sun, equivalent to roughly 126,000 km/h. Venus moves faster than Earth because it orbits much closer to the Sun: its average distance is about 0.723 astronomical units, compared with Earth’s 1 AU. A closer solar orbit requires a greater orbital speed.

Venus completes one revolution in about 224.7 Earth days. Its orbit is also exceptionally close to circular, with an eccentricity of only about 0.0068. As a result, its speed changes relatively little over the course of its year, although it is slightly faster near perihelion and slightly slower near aphelion.

The average orbital speed is not the same as Venus’s rotation speed. Venus rotates extremely slowly and retrograde, taking about 243 Earth days to turn once relative to the stars. Another common mix-up is Earth’s orbital speed, approximately 29.78 km/s.
