How much angular momentum do the solar system's bodies have? Sun: spin angular momentum around its own axis I = 3.86 x 10^(47) kg*m^2 omega = 2.42 x 10^(-6) rad/s L = 9.3 x 10^(41) kg*m^2/s Earth: orbital angular momentum around the Sun. Can either compute via I*omega, or via (m*v*d). omega = 2.42 x 10^(-6) rad/s v = 2.98 x 10^4 m/s L = 2.66 x 10^(40) kg*m^2/s Jupiter: orbital angular momentum around the Sun. Can either compute via I*omega, or via (m*v*d). omega = 1.68 x 10^(-8) rad/s v = 1.30 x 10^4 m/s L = 1.93 x 10^(43) kg*m^2/s It turns out the planets, as a group, and Jupiter, in particular, have much more angular momentum than the Sun itself does.
