IS GRAVITY EVERYWHERE IN SPACE?

Gravity is everywhere, but it’s not always perceptible. Gravitational fields, produced by massive objects, pervade the universe. But we’re not always aware of gravity – only when there’s another force, such as the upward resistance of a planet’s surface, opposing it. So astronauts in space feel they’re in zero gravity.

Any two masses are attracted to each other by gravity, regardless of where they are in the universe
