If the distance of vanus from sun is 0.73 AU, find out the orbital period of the venus in days.

Answer

227.65 days

Explanation

Here, `r_1 = 0.73A.U. T_1 = ?`
`r_2 = 1AU (for earth). T_2 = 1yr = 365 days`
According to Keplar's Law
`T^2 prop r^3 :gt (T_1^2)/(T_2^2) = (r_1^3)/(r_2^3)`
`T_1 = T_2((r_1)/(r_2))^(3//2) = 365((0.73)/(1))^(3//2)`
`T_1 = 365xx0.73xx sqrt(0.73)days`
`T_1 = 227.65 days`
