A satellite of the sun is in circular orbit around the sun, midway between the sun and the earth. Then
Answer & explanation
Correct answer: option 4
$\frac{T_{s}^2}{T_{e}^2}=\frac{\left(\frac{a}{2}\right)^3}{(a)^3}=\frac{1}{8} ; \frac{T_{s}}{T_{e}}=\frac{1}{\sqrt{8}}$
$T_{s}=\frac{T_{e}}{\sqrt{8}}=\frac{365}{2 \sqrt{2}}$ = 129 days
