There are different celestial phenomena of a positional nature, that is, whose nature is related to changes in the position of the stars and resulting in a significant event when observed from Earth. Here we find events that occur at specific times and can be easily predicted (e.g. using online tools or software), to plan their observation. Most of them have no associated effect on our planet, other than providing an interesting instance to contemplate and\/or photograph.<\/p>\n\n\n\n\n

Perhaps the best known celestial phenomenon and one that has been given the most importance in ancient cultures. It occurs every time the new Moon passes right between the Sun and the Earth, obscuring the solar disk for a few moments. Two curious variables coincide: the Sun is 400 times larger than the Moon, but the Moon is in turn 400 times closer to the Earth than the Sun. <\/p>\n<\/div>

Therefore, the solar and lunar disk appear practically the same size, making eclipses possible. There are no eclipses every time there is a new Moon, since its orbit has an inclination of 5\u00ba with respect to the ecliptic, and most of the time the Moon crosses above or below the Sun. A minimum of 2 eclipses occur in a year, of any type. Eclipses are classified according to the portion of the Sun that is covered, having:<\/p>\n<\/div>
