Hi Jim,

Everything has a capacitance to somewhere. Even Mother Earth has a
capacitance. You can select what reference point you like, Moon, Sun, Pluto. I
never really grasped it myself when I took my classes in physics.


It is simple problem in electromagnetics to calculate the isotropic capacitance of the earth to free space, because of the spherical symmetry. The answer is about 700 uF.
