A satellite of the sun is in circular orbit around the sun, midway between the sun and the earth. Then

the acceleration of the satellite is four times the acceleration of the earth the period of the satellite is nearly 129 days the speed of the satellite equals the escape velocity of earth All of the above

All of the above

$\frac{T_{s}^2}{T_{e}^2}=\frac{\left(\frac{a}{2}\right)^3}{(a)^3}=\frac{1}{8} ; \frac{T_{s}}{T_{e}}=\frac{1}{\sqrt{8}}$ $T_{s}=\frac{T_{e}}{\sqrt{8}}=\frac{365}{2 \sqrt{2}}$ = 129 days
