$($a$)$

Calculate the angular momentum $($in kg $$ m$2/$s$)$ of Saturn in its orbit around the Sun. $($The mass of Saturn is $5\mathrm{.}6801026$ kg$,$ the orbital radius is $1\mathrm{.}427109$ km and the orbital period is $29\mathrm{.}5$ y$.)$

$($b$)$

Compare this angular momentum with the angular momentum of Saturn on its axis. $($The radius of Saturn is $6\mathrm{.}027104$ km and the rotation period is $10\mathrm{.}66$ h$.)$
