What are the perihelion and aphelion speeds of Venus? What are the perihelion and aphelion distances of this planet?
Perihelion speed = 35.5 km/s and aphelion speed = 34.5 km/s, nearly. The perihelion = 107.5 million (M) km and aphelion= 108.9 M km.
The orbit of Venus is very close to a circle of radius 108.2 M km. The orbit e = 0.007, nearly.
I have used average speed as 35 km/s and approximation formulas peri-speed = (average speed) X((1+e)/(1-e)) and
aphe-speed = (average speed) X ((1-e)/(1+e))
