Astronomy (from Greek: ἀστρονομία) is a natural science that studies celestial objects and
phenomena. It applies mathematics, physics, and chemistry, in an effort to explain the origin of those objects and
phenomena and their evolution. An
equinox is commonly regarded as the moment the plane of Earth's equator passes through the center of the Sun's disk, which occurs twice each
year, around 20 March and 22-23 September. The principal
astronomical cycles are the day (based on the rotation of the Earth on its axis), the
year (based on the revolution of the Earth around the Sun), and the month (based on the revolution of the Moon around the Earth).
