Britannica micro., 2002: v. 4, p. 352 (A solar eclipse occurs when the Moon, revolving in its orbit around the Earth, moves across the disk of the Sun so that the shadow of the Moon sweeps over the face of the Earth. No sunlight penetrates the umbra, the inner part of the shadow. To observers on the Earth within the umbra, the disk of the sun will appear completely covered by that of the Moon. Such a solar eclipse is said to be total) Hermit eclipse: science: mechanics of solar eclipses, via WWW, Apr. 6, 2006 (A total solar eclipse is when the Sun is completely covered by the Moon ... Here, the moon passes between the Earth and Sun ... at a point in its elliptical orbit when it is relatively close to the Earth. As it does so, it casts a shadow. The umbral part of the shadow (the umbra) is the area where the Sun is totally obscured by the Moon. During a total eclipse, the Moon is close enough to the Earth that part of the umbra falls upon the Earth ... People standing on those parts of the Earth, within the Umbra, see the Sun's face completely hidden by the Moon -- a total eclipse of the Sun) |
