Equation of the orbital velocity of a planet
v = 2πr/T
|Automatic translation||Updated March 24, 2023|
The equation for calculating the speed of rotation of a planet around the sun is a mathematical formula which makes it possible to determine the speed at which a planet orbits around its star. This speed is usually expressed in terms of the orbital period, i.e. the time required for a planet to make a complete revolution around the sun.
Highly elliptical orbits require more complex calculations to determine the average orbital velocity. Although it is applicable to most planets, it should be noted that it does not take into account all the factors that can influence the orbital speed of celestial bodies.
