Show Summary Details


This chapter explains that the lunar eclipses are caused by the Moon falling into the Earth's shadow. The shadow of the Earth moves in direct opposition to the Sun, and is, as it were, “dragged” by it. It is not always the case that the Moon as a whole is darkened by the Earth, but on occasion [the Moon is darkened] just partially. The Moon is eclipsed by falling into the Earth's shadow, and only in that way, can it be seen from the phenomena alone. It affects a total eclipse at a very great height, when very close to the Earth, and at an intermediary distance.

Keywords: lunar eclipses; Moon; Earth; shadow; Sun; total eclipse
