Moment of inertia factor - Wikipedia

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… http://www.columbia.edu/itc/ldeo/earthsci/topic2/topic2_1.html horsell school
