It will be directly overhead again in: This path defines a plane called the plane of the ecliptic (or just the ecliptic). Ecliptic coordinates are convenient for specifying positions of Solar System objects, as most of the planets' orbits have small inclinations to the ecliptic, and therefore always appear relatively close to it on the sky. D. The Earth is closer to the Sun during the sidereal month. The Moon can never leave it, but moves twelve times faster than the Sun. b. The answer is yes and no. Because of the inclination of the Moon's orbit, eclipses do not occur at every conjunction and opposition of the Sun and Moon, but only when the Moon is near an ascending or descending node at the same time it is at conjunction (new) or opposition (full).

If you are in the Moon's umbral shadow, then you will witness: -rises at about the time the Sun sets The only drawback of using the ecliptic instead of the invariable plane is that over geologic time scales, it will move against fixed reference points in the sky's distant background. The Sun appears to move about a degree per day eastward long it. b. every month at new moon. At apogee, the Moon is at its farthest from Earth and thus appears smaller than normal.
