Gate 2011 1.8

1.8 The planet which contributes maximum to the angular momentum of the solar system is

(A) Earth

(B) Mars

(C) Jupiter

(D) Saturn

    98% of the angular momentum is concentrated in the planets and the remaining 2% is present in the sun. In other words, the sun does not rotate fast enough. 

Jupiter is by far the largest of the planets in the solar system. Its mass is 318 times of that of Earth hence contributes maximum to the angular momentum of the solar system as it is proportional to the mass of the body.
