Capacitor as big as the Earth

The Earth can be treated as an isolated spherical capacitor whose capacitance can be written as $4\pi {\varepsilon _0}R$ . Here, R is the radius of the Earth.
Putting the values and solving we get,
$C=710 \mu F$
This shows how large is the unit Farad for capacitance. Even a capacitor of the size comparable to the Earth has the capacity in order of $10^{-4} F$

Capacitance of an isolated sphere is $4\pi\epsilon_0$ R = 710 micro Faraday
