Question

Venus has an average distance to the sun of 0.723 AU. In two or more complete sentences, explain how to calculate the orbital period of Venus, and then calculate it.

Answer 1

 We will use formula for the orbital velocity of Venus, which is v = 35.02 km/s. 
    An average distance to the Sun ( In kilometers ) is:
    R = 0.723 * 149,579,871 km= 108,150,260 km.
    Than we will calculate the orbital period ( T ).
    v = 2 π R / T
    T = 2 π R / v
    T = 2 * 3.14 * 108,150,260 km / 126,072 km/s
    T = 5389.75 s ≈ 224.5 days
    The orbital period of Venus is approximately 224.5 days.
