Syzygy Invitation Suite
In astronomy, a syzygy is a straight line configuration of three celestial bodies in a gravitational system. The word is often used to reference the alignment of the Sun, Earth, and Moon during eclipses. An eclipse occurs when a body totally or partially disappears from view. A lunar eclipse occurs when the Moon passes directly behind the Earth into its shadow. A solar eclipse occurs when the Moon passes between the Sun and Earth, and the Moon fully or partially blocks the Sun. The Moon’s orbit is slightly tilted relative to the Earth’s orbit, so solar eclipses only occur between 2 and 5 times per year. Total solar eclipses are even rarer, and only seen from particular locations on the Earth. This suite was made to highlight the total solar eclipse occurring on August 21st, 2017, viewable from all of North America.
