All Rights Reserved. Pluto's average orbital speed is 4.666 km/s. Since equal areas must be covered in equal intervals of time, the planet's orbit speed has to be the fastest at perihelion and slowest at aphelion. This means that our planet moves around the Sun at an average speed of 30 kilometers per second. (b) Venus. Another way to prevent getting this page in the future is to use Privacy Pass. A.
