Hey ,

Gravitational forces don't stop when you get farther away, they just get weaker. Specifically, if you go twice as far away from the center of the Earth, its gravitational force on you will be one fourth of what it was before. This is the famous "inverse square law": the force is proportional to 1/r21/r2 (an "inverse square"), where rr is the distance from the center of the object.

Eventually, if you get far enough away, the gravitational force from the Earth will be negligible, but what is or isn't negligible depends on context, so there's no set distance.

All the best !
