The Sun has most of the Solar System’s mass, but the planets (mainly Jupiter and Saturn) carry most of its angular momentum. This happened during formation due to redistribution processes:

Solar Nebula Collapse: A rotating gas–dust cloud collapsed, most mass fell inward (Sun), but spin stayed in the disk.

Magnetic Braking: The young Sun’s magnetic field slowed its rotation and pushed angular momentum outward.

Gas Giants Formation: Jupiter and Saturn formed in the outer disk, accreted large masses, and trapped most of the leftover angular momentum.

Orbital Effect: Angular momentum scales with both mass and orbital distance (∝ m√a), so massive planets far from the Sun became the main reservoirs.

Result: The Sun is massive but slow-rotating, while the planets—especially gas giants—carry ~97% of the system’s angular momentum.

Conservation of angular momentum dictates that as the material moves inwards, its rotation speed increases. However, much of the angular momentum is transferred outwards to the forming planets through various mechanisms like gravitational interactions and magnetic braking, which slows down the central star's rotation.

Angular momentum in real do not depenfd on mass implictly instead it depends on moment of inertia and angular velocity sun is moving slowly compare to other planet which have less moment of ineria and less angular velocity
