...points move completely round the ecliptic and regain their original positions in about 26000 years. The plane of the ecliptic is inclined to the plane of the equator by an angle, which is called the obliquity of the echptici The apparent displacement of a celestial...

...in a circular path. This path is called the ecliptic. It is not the same as the celestial equator. The plane of the ecliptic is inclined to the plane of the equator 23^- degrees, so that the sun each year reaches that distance either side of the celestial equator....
