gravitational field
Invisible attractive region
A gravitational field is the region of space around a massive object where other objects experience a gravitational force.
The field's strength decreases with distance from the source.
Earth's gravitational field keeps the moon in orbit and pulls objects toward its surface.
In physics, fields allow gravity to be described as a property of space itself rather than action at a distance.
