Answer
Jupiter's orbital period is 11.8 years.
Work Step by Step
We will use the following relation to find the orbital period of Jupiter. T represents the orbital period of the planet while R represents the radius of the planet.
$(\frac{T_J}{T_E})^2 = (\frac{R_J}{R_E})^3$
$(\frac{T_J}{T_E})^2 = (5.19)^3$
$(\frac{T_J}{T_E})^2 = 139.8$
$(\frac{T_J}{T_E}) = \sqrt{139.8}$
$T_J = 11.8\times T_E = 11.8 ~years$
Jupiter's orbital period is 11.8 years.
