Solar Eclipses One consequence of the Moon's orbit about the Earth is that the Moon can shadow the Sun's light as viewed from the Earth, or the Moon can pass through the shadow cast by the Earth. The former is called a solar eclipse and the later is called a lunar eclipse . The small tilt of the Moon's orbit with respect to the plane of the ecliptic and the small eccentricity of the lunar orbit make such eclipses much less common than they would be otherwise, but partial or total eclipses are actually rather frequent. Frequency of Eclipses For example there will be 18 solar eclipses from 1996-2020 for which the eclipse will be total on some part of the Earth's surface. The common perception that eclipses are infrequent is because the observation of a total eclipse from a given point on the surface of the Earth is not a common occurrence. For example, it will be two decades before the next total solar eclipse visible in North America occurs. The next total solar eclipse will be on August 11, 1999 , with the path of totality crossing the North Atlantic, Europe, the Middle East, and India. In this section we consider solar eclipses and in the next we discuss lunar eclipses. Geometry of Solar Eclipses The geometry associated with solar eclipses is illustrated in the following figure (which, like most figures in this and the next section, is illustrative and not to scale).

Lunar Eclipses for Beginners Phases of the total lunar eclipse 1993 Nov 29. W hat is an eclipse of the Moon? What causes eclipses and why? How often do eclipses happen and when is the next eclipse of the Moon? You'll learn the answers to these questions and more in MrEclipse's primer on lunar eclipses. T he Moon is a cold, rocky body about 2,160 miles (3,476 km) in diameter. It has no light of its own but shines by sunlight reflected from its surface. The Moon orbits Earth about once every 29 and a half days. As it circles our planet, the changing position of the Moon with respect to the Sun causes our natural satellite to cycle through a series of phases: New, New Crescent, First Quarter, Waxing Gibbous, Full, Waning Gibbous, Last Quarter, Old Crescent and back to New again. Phases of theMoon. T he phase known as New Moon can not actually be seen because the illuminated side of the Moon is then pointed away from Earth. The rest of the phases are familiar to all of us as the Moon cycles through them month after month. Did you realize that the word month is derived from the Moon's 29.5 day period?

What Causes an Eclipse? What Causes an Eclipse? An eclipse occurs at those times when the Moon moves into a position of direct alignment with the Sun and the Earth total lunar eclipse But the gentle beauty of a lunar eclipse pales in comparison with the truly awesome spectacle of a total solar eclipse , which occurs when the new Moon passes directly between the Sun and the Earth. In the narrow path of totality umbra corona dark disk of the Moon totally obscures the bright Sun penumbra Not all solar eclipses are total. During a partial solar eclipse , only the penumbra touches our planet. The umbra passes either just above the North Pole or just below the South Pole, completely missing the Earth. No total eclipse is visible only partial phases can be seen. A third type of solar eclipse occurs when the Moon's umbra passes across the Earth, but is not quite long enough to touch the surface; the shadow cone diminishes to a point before reaching the Earth. This effect happens when the Moon is farther out in its orbit around the Earth. The Moon appears slightly smaller and is not large enough to completely cover the Sun. When the Moon is centered over the Sun, a ring of sunlight remains visible around the edge. This type of eclipse is called an annular eclipse . (Annular comes from the Latin word meaning "ring.") Because the Sun is not completely covered by the Moon, the rare and dramatic effects of a total solar eclipse (onset of darkness and view of the corona) are not present at either annular or partial eclipses of the Sun.

Lunar Eclipses As we have noted in the preceding section, the Earth casts a shadow that the Moon can pass through. When this happens we say that a lunar eclipse occurs. Just as for solar eclipses, lunar eclipses can be partial or total, depending on whether the light of the Sun is partially or completely blocked from reaching the Moon. The following figure illustrates a total lunar eclipse with the Moon lying in the umbra of the Earth's shadow. A Lunar Eclipse During a total lunar eclipse the Moon takes on a dark red color because it is being lighted slightly by sunlight passing through the Earth's atmosphere and this light has the blue component preferentially scattered out (this is also why the sky appears blue from the surface of the Earth), leaving faint reddish light to illuminate the Moon during the eclipse.

Ce sujet est très intéressant , mais on se rend compte bien vite des difficultés , surtout au niveau des calculs... Il y a donc une partie principale avec l'explication des phénomènes écliptiques , et une partie calculs , tout d'abord simplifiés , puis les éléments de Bessel. L'étude des éléments de Bessel est quasiment inévitable pour un TIPE traitant des éclipses. Notre source principale fut le site du Bureau des Longitudes sur lequel figurent de nombreux schémas et les éclipses y sont étudiées en long et en large. Toutes nos sources sont inscrites dans la bibliographie du TIPE. Vous verrez tout ça... Si vous avez une quelconque question , n'hésitez pas à me contacter ! Bon courage !
