| | Mercury |
 | | As the moon is locked with one side to the earth, its primary, so, and for the same reason, Mercury was thought to be locked permanently with one side to its primary, the sun. |
 | | It was estimated that when the planet was in the process of formation, the sun must have caused in it tides, and this, in turn, must have exerted a tidal friction, and breaking of axial rotation. |
 | | This view conflicts with both standard alternativesof nebular and of tidal theories of the origin of the planetary family and with the assumption that the planets occupy the same orbits since billions of years. |
