Transformers:: An Alien race of autoshape robotic race in Science Fiction :: Tug-of-war definition The late Isaac Asimov suggested a distinction between planet-moon and double-planet systems based on what he called a "tug-of-war" value. This quantity is simply the ratio of the gravitational force between the planet and satellite, and the satellite and Sun. In the case of the Moon, the Sun "wins" the "tug of war," and the Earth and Moon form a double-planet system. The opposite is true for most (but not all) of the other satellite systems in our Solar System, including the Pluto-Charon system, which would be classified as planet-satellite systems.
