What property of the gas giant planets would account for their having more moons than the number of moons that orbit Earth?

• Gas giants rotate more rapidly than Earth, so they eject more material that could form natural satellites.

• Gas giants are less dense than Earth, so they contain less material that could form natural satellites.

• Gas giants are more massive than Earth and thus have greater gravitational forces, so they could attract more objects.

• Gas giants are farther from the sun than Earth, so there are fewer objects in that part of space to attract into orbits.
