-an eclipse is an ‘astronomical event’ that occurs when an ‘astronomical object’ is temporarily ‘obscured’, either by passing into the ‘shadow’ of another ‘body’ or by having another ‘body’ pass between it and the ‘viewer’-
.
(this alignment of 3 celestial objects is known as a ‘syzygy’)
(apart from ‘syzygy’, the term ‘eclipse’ is also used when a spacecraft reaches a position where it can observe 2 celestial bodies so aligned)
(an ‘eclipse’ is the result of either an ‘occultation’ (aka ‘completely hidden’) or a ‘transit’ (aka ‘partially hidden’))
(the term ‘eclipse’ is most often used to describe either a ‘solar eclipse’, when the moon’s shadow crosses the earth’s surface, or a ‘lunar eclipse’, when the moon moves into the earth’s shadow)
(however, it can also refer to such events beyond the ‘Earth–Moon’ system: for example, a planet moving into the shadow cast by one of its moons, a moon passing into the shadow cast by its host planet, or a moon passing into the shadow of another moon)
(a binary star system can also produce eclipses if the plane of the orbit of its ‘constituent stars’ intersects the observer’s position)
(for the special cases of ‘solar’ and ‘lunar’ eclipses, these only happen during an “eclipse season”, the 2 times of each year when the plane of the earth’s orbit around the sun crosses with the plane of the moon’s orbit around the ‘earth’)
(the type of ‘solar eclipse’ that happens during each season (whether ‘total’, ‘annular’, ‘hybrid’, or ‘partial’) depends on apparent sizes of the ‘sun’ and ‘moon’)
(if the orbit of the ‘earth’ around the ‘sun’, and the moon’s orbit around the ‘earth’ were both in the same plane with each other, then eclipses would happen each and every month)
(there would be a ‘lunar eclipse’ at every ‘full moon’, and a ‘solar eclipse’ at every ‘new moon’)
(and if both orbits were perfectly circular, then each ‘solar eclipse’ would be the same type every month)
(it is because of the ‘non-planar’ and ‘non-circular’ differences that ‘eclipses’ are not a common event)
(‘lunar eclipses’ can be viewed from the entire nightside half of the ‘earth’)
(but ‘solar eclipses’, particularly a ‘total eclipse’, as occurring at any one particular point on the earth’s surface, is a rare event that can span many decades from one to the next)
