Is the eccentricity of the lunar orbit constant?

[QUOTE="WernerQH, post: 6652069, member: 686891"] No, the eccentricity varies between 0.044 and 0.067 during the course of half a year; the value e = 0.0549 is just an average. The cause is the tidal force of the sun on the earth-moon system. When the direction to the sun is aligned with the major axis, the eccentricity is biggest, and smallest when aligned with the minor axis. Since the ellipse is not fixed in space, but rotates once every 8.8479 years, the confusing graph will look different from year to year. [/QUOTE]
