A planet revolves around sun whose mean distance is $1.588$ times the mean distance between earth and sun. The revolution time of planet will be ........... $ years$
$\frac{{{T_{{\rm{plant}}}}}}{{{T_{{\rm{earth}}}}}} = {\left( {\frac{{{r_{{\rm{plant}}}}}}{{{r_{{\rm{earth}}}}}}} \right)^{3/2}} = {(1.588)^{3/2}} = 2$
${T_{{\rm{planet}}}} = 2\;year$
