gravity field
Attracts objects nearby
A gravity field is the region of space surrounding a massive object where gravitational force can be detected.
Every object with mass generates one, though only planets, stars, and similarly massive bodies produce fields strong enough to matter practically.
Scientists map gravity fields to understand planetary structure and guide spacecraft trajectories: The probe measured variations in the Moon's gravity field.
