Gravity between any two masses
Every object with mass pulls on every other object with mass through gravity, not just Earth pulling on things near it: the more mass either object has, the stronger that pull is. This is why the sun's enormous mass holds planets in orbit, while a planet's own much smaller mass is still enough to hold its own moons in orbit around it.
