Because a negative amount of work is done to bring an object closer to the Earth, gravitational potential energy is always a negative number when using this reference point. A satellite of mass is launched from the surface of the Earth into an orbit of radius , where is the radius of the Earth.

wait ill explain
the gravitational potential energy is going against the earth so it is negative
simple way
Ok

Gravitational potential energy is stored by work done against the gravitational force, hence, is negative.
