The Sun has by far the lowest moment of inertia factor value among Solar System bodies; it has by far the highest central density (162 g/cm , compared to ~13 for Earth ) and a relatively low average density (1.41 g/cm versus 5.5 for Earth). Saturn has the lowest value among the gas giants in part because it has the lowest bulk density (0.687 g/cm ). Ganymede has the lowest moment of inertia factor among solid bodies in the Solar System because of its fully differentiated interior, a result i… WebThe moment of inertia of the Earth about its axis of rotation is 9.83 × 10 37 kg.m 2 and its angular speed is 7.27 × 10-5 rad/s.
