Heya, here is the answer you're looking for :-
The gravitational potential energy of a body depends on the reference point for measurement. By convention, we usually define gravitational potential energy at "infinity" as zero.
Consider a small object at a particular distance from Earth. Positive work must be done by gravity to move it towards the Earth. The object would gain kinetic energy but lose potential energy, if it moved freely under gravity. Positive work must also be done against gravity (by an external force) to move the object away from the Earth. The object would gain potential energy if moved away from the Earth. But it has zero potential energy at infinity. Hence it must have negative potential energy when closer to Earth than infinity.
Hope this helps
