the proximity of the moon in relation to earth and earth in relation to the sun also has an effect on tidal ranges. the moon moves around earth in an elliptic orbit that takes about 29 days to complete. the gravitational force is greatest when the moon is at perigee — closest to earth — and least when it is at apogee — farthest from earth — about two weeks after perigee. the moon has a larger effect on the tides than the sun, but the sun's position also has an influence on the tides. earth moves around the sun in an elliptic orbit that takes a little over 365 days to complete. its gravitational force is greatest when the earth is at perihelion — closest to the sun in early january — and least when the earth is at aphelion — farthest from the sun in early july.

precession, nutation, and intrinsic rotation (spin) are defined as the movements obtained by changing one of the euler angles while leaving the other two constant. these motions are not expressed in terms of the external frame, or in terms of the co-moving rotated body frame, but in a mixture. they constitute a mixed axes of rotation system, where the first angle moves the line of nodes around the external axis "z", the second rotates around the line of nodes "n" and the third one is an intrinsic rotation around "z", an axis fixed in the body that moves.
