eclipse | has definition Occultation of one celestial body by another which passes between it and the observer. The solar eclipse is caused by the passing of the Moon between the Sun and the Earth in this way; such an eclipse may be complete (total) or incomplete (partial). Eclipsing binary stars also accord with this pattern. Alternatively - and exceptionally - a lunar eclipse is caused by the passage of the Earth between the Sun and the Moon, so that the Earth's shadow falls across the Moon, again either totally or partially, depending upon the position of the observer. | ![has source: Abbot, D. 1984 Astronomers, Peter Bedrick Books, New York, 2001-09-27 09:30:01.0 has source: Abbot, D. 1984 Astronomers, Peter Bedrick Books, New York, 2001-09-27 09:30:01.0](facet.gif) |
