The mass of the sun is 99.87% of the solar system, and its angular momentum is 0.73% of the solar system.

The mass of the planets in the solar system is 0. 13% of the solar system, and the angular momentum is 99.27% of the solar system.

Angular momentum: a physical quantity that maintains the original state characteristics of an object that is already rotating.

Mathematically, angular momentum is the product of mass, velocity and rotation semicurvature. Formula: L=rmv.

Law of conservation of angular momentum: When the rotating system is not affected by external torque, angular momentum is conserved.
