What is the distance to which the earth's gravitational force extends?

Answer 1

Here is the formula for the strength of the gravitational force:

F = G m1m2/R2

'm1' and 'm2' are the masses of the two objects attracting each other,

and 'R' is the distance between them.

There's nothing in the formula that says "Only as far out as this maximum distance".

The gravitational force between two objects extends to any distance you want to

think about, and past it. It becomes weaker as the distance grows, but it never

shrinks to zero, no matter how far apart the objects are.

There is a force of gravity between a grain of sand on the farthest planet orbiting

the farthest star in the farthest galaxy, if any of them exist, and your pinky fingernail.

Answer 2

The force of Earth's gravity extends infinitely into space, although it diminishes in strength as distance from Earth's center increases. However, its influence becomes negligible at distances much further out into space, beyond the solar system.
