Correct. More precisely, it depends on the mass of the two bodies and the
distance between their *centers of gravity*. For a planet, the center of
gravity is more or less at the center of the planet. Thus, for a given mass,
a greater volume (hence a greater distance between the planet's surface and
its center of gravity) means less gravitational attraction between the planet
and an object located on its surface.
But this is somewhat off-topic, so I'll shut up now...
