I'm struggling a bit with angular momentum.

Consider the satellites of the planets orbiting their respectivehost planets while those planets orbit the Sun. Galileo'sobservation of Jupiter's \"moons\" were an inspiration to thedevelopment of universal laws of motion and gravity that coulddescribe not only effects here on Earth, but throughout theuniverse as well. Jupiter's satellite Europa has oceans under itsice and may even host life. It orbits the planet on a nearlycircular path with a radius of 670,900 km and completes its orbitevery 3.55 Earth days. Use Newton's universal law of gravitation tofind the mass of Jupiter. Knowing Jupiter's mass, and that itorbits the Sun on the average (it has an elliptical orbit with aneccentricity of 0.05) at 7.8×108 km from the Sun in 11.86 years,what is its angular momentum? Compare Jupiter's orbital angularmomentum to the angular momentum of the rotating Sun, which is aspinning sphere of radius 695,700 km and mass 1.99×1030 kg thatcompletes a turn in 25 days (with respect to distant stars).
