ECLIPSE. An obscuration of a heavenly body by the interposition of another, or during its passage through the shadow of a larger body. An eclipse of the sun is caused by the dark body of the moon passing between it and the earth. When the moon's diameter exceeds the sun's, and their centres nearly coincide, a total eclipse of the sun takes place; but if the moon's diameter be less, then the eclipse is annular.
