What is the binding energy of a satellite? Write its equation.

(N/A) The minimum amount of energy required to remove a satellite from its orbit and take it to infinity,where it is no longer under the influence of the Earth's gravitational field,is called the binding energy of the satellite.
The total energy $(E)$ of a satellite of mass $m$ orbiting at a distance $r$ from the center of the Earth (mass $M_E$) is given by $E = -\frac{GM_E m}{2r}$.
At an infinite distance from the Earth,the gravitational potential energy and kinetic energy of the satellite are both zero,meaning the total energy at infinity is zero.
To move the satellite from its orbit to infinity,we must provide an external energy equal to the negative of its total energy. Thus,the binding energy $(BE)$ is:
$BE = -E = \frac{GM_E m}{2r}$
Where $r = R_E + h$,with $R_E$ being the radius of the Earth and $h$ being the height of the satellite above the Earth's surface.
